Compact IO Module DI-16-C

Digital open collector output module, 16 inputs, max 100mA/channel.

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

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 auto-detect the communication speed of the bus (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 datasheet.
Modbus loop termination: On the last module, the Modbus loop must be closed by connecting a 120 Ω resistor between the A and the B side of the RS-485 loop.

DI-16-C Fidelix Digital input module

– 16 digital inputs
– Indication, alarm, and heart rate recording
– Galvanically isolated channels
– Multicolored LED indications
– Pluggable connection terminals
– RS-485 communication with Modbus protocol
– Mounting on DIN rail
The DI-16-C is used to read digital signals for indications, alarms or heart rate measurements.
Each channel can be configured individually and has a green and a red LED to show the current status.
Quick and easy installation as the power supply and communication are integrated into the DIN rail.
