Analogue input module, 8 inputs.
- 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 analogue input module is used to read input signals from active and passive sensors. Its 8 individually configurable channels can read data from resistive sensors, current loops, voltage messages, and digital indications.
Poll the module from a serial Modbus master controller to get reliable, accurate, precise, and fast readings from your field equipment.
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.
