New DC Output SSR Models:  DIN Rail, Panel Mount and Plug-in Solid State Relays

Sensata / Crydom are pleased to announce the expansion of their DC Output Solid State Relay offering. The new models extend across 4 popular series, including the SeriesOne DR, CN Series, EL Series and ED Series.

The number of applications for DC output relays is increasing, mainly due to the increase of portable devices, solar powered systems and electrification initiatives. Taking advantage of improved switching components, Sensata is expanding the current handling capability of select families of DC output SSRs, while maintaining the same form and factor.

The IoT Gateway allows virtually any sensor to be monitored from anywhere with a Cellular connection.

As standard the IoT Gateway accepts inputs from the following:
• Up to 128 IWT Industrial Wireless Transmitters
• 4 off 4-20 mA or 0-10 V analog inputs
• 8 off digital inputs
• 4 off Relay outputs
• Any Modbus enabled instrument over RS-232, RS-485, or Ethernet
• I²C and/or SPI sensors (may need custom software)
• The IoT Gateway uses the MQTT protocol to send this data to remote servers using the built-in 2G/3G or 4G modem.

As Standard, the remote server runs a standard web-based SCADA project which allows monitoring of the inputs and logged data from any device with an Cellular connection.
This package can also provide automated custom reports and email or SMS alarm messages.
Other options include a built-in GPS module and a local display showing input values and set-up information.

Features:
• Easy, real-time monitoring of remote assets via the internet
• Includes 2G/3G/4G modem and digital communications ports for data acquisition
• Input types include Analog/digital I/O, IWT wireless sensors, and I²C /SPi sensors
• Can be battery or 12-24 V dc powered

Bus Stop Buttons Are Now Wireless & Battery-Free Using Energy Harvesting Technology from ZF

Thanks to the wireless and battery-free switch technology from ZF, there are various possible application fields to increase connectivity, flexibility, and convenience. Bus stop buttons are another smart application integrating the inductive RF generator module. The target is to avoid cabling (up to 100m) and expensive maintenance work caused by cable breaks in buses. The energy harvesting switch guarantees design freedom and reduces maintenance work to a minimum as it has a lifetime of over 1,000,000 switching cycles.

The energy harvesting switch can be integrated directly into the plastic housing of the stop request buttons in buses. The compact design (20.1 x 7.3 x 14.3 mm) makes it easy to integrate. In addition, the ZF radio switch generates a voltage pulse by mechanical actuation as it relies on the inductive principle. Therefore, RF commands can be reliably sent via commercially available radio protocols such as EnOcean3.0 at a frequency band of 868MHz. In this case there is no risk of RF interference with Bluetooth devices which operate at a 2.4 GHz frequency range. Altogether, the radio switch is completely free of batteries or cabling, allows a reliable RF transmission and offers a high degree of flexibility when it comes to mounting in buses.

Each RF switch has a unique ID and can be programmed individually. This means that each stop request button can be assigned to a specific command group, such as opening doors at the front, back, or initiating measures for wheelchair users. The buttons are paired to the central receiver unit, which is again connected to the electrical bus system. Depending on the received command, the receiver triggers a visual or acoustic signal to give the bus driver appropriate instructions.

• Save time during testing operation thanks to "plug & play" concept (socket + test plug)
• Simplify testing: simultaneous testing of 1 to 4 independent circuits on the same socket
• Secure the testing operations thanks to "make before break" test principle, colors and mechanical codings, covers

Main features:
• ESSAILEC allows: measurement, current or voltage injection, repair, device replacement
• IP20 protection degree for the socket and IP40 with the lid
• Sealed cover
• Panel and switchboard mounting : base, flush, rack, TH35 rail
• Several wiring technologies, wire connection up to 10 mm²
