Digital pulse input - DIN rail measuring device / for flow sensors, rotary encoders, etc. / 2 channels /
RS485 interface / Modbus RTU / ASCII
The PCE-SM3 DIN rail measuring device is suitable for making binary signals or pulse signals bus-capable. It is thus possible, for example, to convert signals from flow sensors, rotary encoders, etc. to RS485 Modbus. The transmission method via Modbus is RTU or ASCII. The input module is mounted on a DIN rail. The DIN rail measuring device is parameterized via the front-end RS232 interface and the configuration software.

- 2 digital inputs
- RS485 Modbus
- RTU or ASCII transmission
- Galvanically isolated inputs and outputs
- Configuration via RS232
- DIN rail mounting
- Selectable supply voltages
- Easy to operate
