Compact IO Module TRIAC-8-C

8-channel analogue output module.

• Screwless installation with click-on DIN-rail communication bus and power connectors
• Push-in spring connectors for cables
• Individually detachable terminal blocks per channel

The 8-channel Triac module sends control signals to Triac field equipment. Its 8 individually configurable channels can send control signals between 0 and 100%, and each has parametrisable safeguard values in case of a communication rupture from a serial Modbus master controller.

T Bus connecter (Terminal C) required for MODBUS + and – connection, along with other supply voltage 24VDC, and consumes 15mA.

If more than 1 module is being installed, you only need one terminal connector. If connecting, say, 10 of the same or different modules, only one T Bus connector is required.

Communication: Modbus RTU (RS485) at speeds up to 57600 bps. Use no parity, 8 data bits and 1 stop bit. The module will automatically detect the bus communication speed (9600, 19200, 38400, or 57600 bps).
Modbus address: The address of the module can be set from 1 to 63 by changing the position of dip-switches 1-6. Each dip switch represents a binary value, as indicated on the module and the datasheet.
Modbus loop termination: On the last module, the Modbus loop must be closed by connecting a 120 Ω resistor between the A and B sides of the RS-485 loop.
