The Finder 86 series miniature plug-in time delay modules can be used with a wide range of Finder rail-mounted relay socket combinations including the latest 46 Series Industrial Relays. The timer modules in the 86 series are among the smallest and most versatile currently available.

The modules offer the ability to introduce a time delay to the operation of relays, and are ideally suited for use with control circuits that require a delayed relay response in order to ensure the correct functioning of logic or sequence. The timer modules can either be fitted during panel assembly or retrofitted without any need for re-wiring or for the introduction of components requiring additional panel space.

The time delay modules are compatible with sockets having both screw and screwless connection formats, and can be used with relays from Finder’s 40, 44, 46, 55, 60 and 62 series, therefore providing the facility for multiple delayed contact combinations from 1 CO to 4 CO with switched current ratings from 7A to 16A at 250V AC or 30VDC.

ON delay and ON pulse functions, four time delay ranges spanning 1.5s to 64 min and a 12 - 24V AC or DC operating voltage mean that fewer models need to be held in stock to cover the whole range of available specifications.

By ensuring that all future introductions of relay socket combinations offer full compatibility with the 86 series, Finder guarantees the user continued maximum flexibility of operation for the widest variety of applications.

New from Finder is a range of 35mm rail mounting sockets featuring screwless terminations. Designed for use with Finder’s 34, 40, 41, 44 and 55 series plug-in relays and 85 series timers, the sockets can be used in any application where power and control wiring is terminated. The sockets will allow panel builders, machine builders, system integrators, OEMs and installers to make a reliable and vibration-resistant connection to the relay or timer in the shortest possible time.

Conventional screw terminals must be tightened to a specified torque during assembly: this process is time-consuming, and it is difficult to ensure that it has been performed correctly. As a consequence, screw connections can work loose under high levels of vibration, either in operation or when being transported. Screwless connections are achieved by means of two metallic blades that are both under tension, which will always force a strong closing action on the wire.

The sockets are all suitable for 35mm rail (EN 50022) mounting and, depending upon type, may also be suitable for panel mounting. The sockets offer the same features and performance as their screw terminal equivalents, allowing the designer the choice of a screwless termination without compromising on other parameters.   Many of the sockets accept Finder’s range of coil indication, EMC suppression and timer modules, and all feature plastic retaining and release clips .

The wide range of relay socket styles that are now available in the screwless format means that the benefits of reduced wiring time and termination reliability can be offered across a large selection of Finder’s relay types and ratings.

These sockets are the result of Finder’s total in-house capability for product design and expertise in advanced manufacturing technology; encompassing the design and manufacture of all precision mould and press tools, automated assembly machinery and test equipment.

New from Finder is the 46 Series miniature industrial relay range. The 46 Series has evolved from the successful PCB mount 40 Series, and provides both single-pole and two-pole contact configurations for use in control panels and systems. The key characteristic of this new range is its full terminal compatibility with a widely used but single sourced de-facto industry standard. The Faston spade/blade terminals provide secure and reliable connections between the relay and the associated 97 Series socket, over and above that achieved by its predecessor.

Says Finder’s Sales Manager Ted Waller, “This type of relay with spade terminals has been primarily single-sourced until now. The introduction of the 46 Series provides the customer with a real choice, offering a higher current rating than the competing product, and a unique range of optional plug-in modules for greater functionality that is not available elsewhere”

The 46 Series relays are available with either AC or DC coils, and benefit from a host of advanced features and options, including a mechanical flag indicator and manual test button that can be used in momentary or latching mode - useful during commissioning, fault tracing and override situations.  A version with LED indication is also available.

The 46.52 relay has a two-pole changeover (DPDT) configuration and a maximum rated current of 8A, while the single-pole changeover (SPDT) 46.61 model is rated at 16A maximum.

The associated 97 Series rail mounted sockets feature a flip-out retaining and release clip for easy removal of the relay. Uniquely these sockets accept an extensive range of time-delay, coil indication and EMC suppression modules and an 8-way jumper link that reduces the time taken to wire common connections.

As an alternative to using the rail mounting socket the relay can be secured by an optional flange-mount bracket allowing direct mating with Faston connectors.

The terminal arrangement and pitch of the 46 Series are fully compliant with existing relays of this type, and the new relays can be used as a drop-in replacement for industry standard products.

Crydom the leading manufacturer of Solid State Relays (SSR’s) has launched a completely new range of microcontroller based devices. The MCTC is a self contained temperature controller in a single industry standard panel mount package.

The series combines all the necessary functions to accurately regulate temperature. With a simple set up procedure, they provide accurate control for designers for heater and cooling loads of up to 90A AC.

The MCTC requires a non-regulated low drive current DC source (10-32Vdc, 32mA max). The devices have an internally compensated thermocouple input, set to accept J or K types. Five available temperature ranges offering heating control over 37°C to 590°C and an inverse function for refrigeration down to –73°C. Setpoint adjustment is achieved by either low voltage dc or 4-20mA inputs. There is also separate enable/disable input to switch the load.

Integrated zerocross burst firing and proportional derivative control avoids setpoint overshoot. Operators can easily see the controller’s status with separate LED indication for setpoint condition and output status. Load voltage switching can be either 280Vac or 480Vac suitable for both single and three phase systems. Connections are simple screw connections both control and load side. The industry standard package makes it suitable for Crydom’s range of heatsinks.
