Crydom Introduces the RHP, It's New Line of High Power Hybrid Solid State Contactors

February 13, 2009

clogo.jpg

Crydom has combined solid state and mechanical switching
technologies to create a contactor with longer operational life
than standard EMR's in an industry standard package!

Crydom, global expert in solid state relay technology, introduces a new line of high power Hybrid Solid State Contactors for use in Heating and Lighting applications where Mercury Displacement Relays have previously been applied, and where life cycle constraints limit the use of Definite Purpose Contactors.

RHP Series.jpg       

crydom_rhp.pdf

Mounting identically to a standard 3 phase DP (Definite Purpose) contactor, and featuring full load life cycle ratings of greater than 2 million operations, the new RHP line includes 3 phase contactor configurations rated at 120, 240, 280 or 600 VAC at 40 or 50 amp load ratings per phase at 65 degrees C ambient temperature. Control voltages of 24, 120 or 220 VAC, and unique logic compatible 5, 12 or 24 VDC input control options are offered. The RHP line is UL and cUL approved and CE certified.

The RHP line incorporates Crydom's proven Hybrid SSR technology that utilizes contactless Solid State Relay turn on and turn off performance, coupled with the very low on state power dissipation characteristics of contactors, thus eliminating the need for heat sinking. The higher power switching capabilities of the new RHP line means that in those applications where Mercury Displacement Relays are no longer welcome, the OEM manufacturer now has a cost effective alternative available. Similarly, in applications where contactor life cycles are a limiting or maintenance cost concern, the new Crydom RHP Contactor provides significantly longer operational life capability in an identical mounting package.

Finder Relays Extends it's 19 Series of 35mm DIN Rail Module Relay

December 5, 2008

Finder.jpg

Finder has announced new additions to its 19 Series of 35mm DIN rail module relays, adding override and status monitoring modules to the series.

Building management system (BMS) designers, panel builders and installers will find the new override modules essential for providing a manual override of a BMS controller or programmable logic controller, in an emergency situation or during maintenance.

FIN0057_19Series.jpg

The ability to manually override automatic systems provides crucial control in an array of situations, control that is typically missing in such systems.  This may include a controller failure, or where maintenance or safety issues must take precedence. 

Typically this can provide control over pumps, fans solenoid valves or motors, where manual intervention is required.

The status modules address a significant drawback of commercial or proprietary controllers; a lack of clear visual signal identification.  The new status module allows BSM and panel designers to set the colour of the status LED during installation, to create a more obvious alert indication.  This enables quick identification of operational status, particularly in complex systems, minimising downtime during fault conditions or routine maintenance.  An analogue output module has also been added to the range, providing a user-defined output between 0 – 10V, for proportional output setting or speed adjustment.

Finder Relays (10 Series) for Automatic Lighting Control Feature Unique Light Feedback Compensation

July 31, 2008

Finder.jpg

Finder has announced the new 10 Series light dependent relays, which have the ability to control lighting according to ambient light levels. These relays will be of particular interest to designers, specifiers and installers both of lighting and of lighting control systems, and will find applications in the automatic control of exterior lighting around factories, loading bays, schools, offices and similar areas where lighting is required for security or safety reasons during the hours of darkness.

FIN0056_10 Series.jpg

There is a growing need to reduce energy consumption, maintenance and replacement costs by ensuring that essential exterior lighting is lit only during times when the ambient natural light falls below an acceptable level, and it is this requirement that the 10 Series has been developed to address.

The 10 Series relays feature an integral photoelectric sensor combined with innovative light feedback compensation circuitry designed by Finder, which prevents the controlled lighting from ‘hunting’ on and off due to the perceived increase in ambient light when lights are automatically turned on. This feedback capability is achieved by monitoring the effect of the controlled lighting over a ten-minute period, which ensures compatibility with slow starting gas discharge lamps. ON and OFF delay times are reduced to zero for the first three cycles, which aids set up and commissioning and reduces installation time.

The new family of relays includes both single-pole and two-pole output types rated at 16A, and also a miniature type, 10.51, with a single 12A output. The double output 16A 10.32 allows Live and Neutral switching, while model 10.41 has a single 16A NO output for Live switching.  All the relays in the series operate from either a 120V or 230V AC supply.

The ambient light switching level is adjustable in the range 1 – 80 lux, and the relays are capable of switching up to 2.3kW of incandescent or halogen lighting, allowing the switching behaviour to be optimised according to both the needs of the individual application and the physical location of the unit.

Finder Launches Call and Reset Relays for Remote Alarm Call Systems

July 30, 2008

Finder.jpg

Finder has announced the 13.12 Call and Reset Relay, which is designed to activate an alarm at a remote point and provide local indication of activation. The relay will be of particular interest to designers and installers of attendant call systems in hospitals and care homes, and to contractors involved in the provision of facilities into residential and commercial buildings where occupants may need to call for assistance.

FIN0055_1312.jpg

An ageing population is creating a growing demand for both short-term and long-term facilities providing care and supervision - hospitals, care homes, assisted living developments, hotels and similar premises - and the means to summon assistance in these facilities is a fundamental requirement. The 13.12 relay is a conveniently packaged product that addresses this need, and which can easily be installed in new buildings or retrofitted in existing sites.

The 13.12 features dual outputs, offering the facility for both a remote alarm signal and a local indication of activation to be activated simultaneously. Independent set and reset inputs provide flexibility in the location of activation and acknowledgement points. The relay output contacts are rated at 8A, which means that they are capable of directly switching incandescent lamp loads up to 800W. Set and reset inputs are both continuously rated, so that no damage is caused to the product if it is inadvertently left permanently activated. The relays are suitable for 35mm rail or panel mounting if an additional bracket is used. The length of the cable run between the set/reset points and the unit can be up to 100m, allowing multiple units to be placed in a convenient centrally located control panel for ease of maintenance and space saving.

The 13.12 relays are housed in a compact 17.5mm single unit width rail mounting enclosure.
