tM-P3R3 RS-485 I/O Module, 3-ch Wet DI and 3-ch Power Relay Output
The tM-P3R3 CR is an RS-485 I/O module with 3 wet-contact digital inputs and 3 Form A power relay outputs, photocoupler isolated for on/off control in automation systems.
- Three wet-contact digital inputs, configurable as sink- or source-type through wiring
- Three Form A (SPST N.O.) power relay outputs, each photocoupler isolated
- All digital input channels can be used as 16-bit counters (maximum 65535)
- Programmable power-on and safe digital output values
- Dual watchdog with 3750 VDC intra-module isolation and 4 kV ESD protection
- Single RS-485 port supporting DCON, Modbus RTU and Modbus ASCII

Produktinformation "tM-P3R3 RS-485 I/O Module, 3-ch Wet DI and 3-ch Power Relay Output"
tM-P3R3 CR is a DIN-rail RS-485 I/O module that combines three wet-contact digital inputs with three Form A (SPST N.O.) power relay outputs. Each channel is photocoupler isolated, and the digital inputs accept either sink- or source-type wiring, so one module suits a wide range of field devices and switch arrangements.
Every digital input can also be used as a 16-bit counter, with a maximum count of 65535 and an input frequency of 100 Hz. Power-on and safe digital output values are programmable, so outputs can be set to a known state when the module starts or when communication is lost. A dual watchdog and 3750 VDC intra-module isolation add to its suitability for control panels.
The module communicates over a single RS-485 port using DCON, Modbus RTU or Modbus ASCII, at baud rates from 1200 to 115200 bps. It is powered from 10 to 30 VDC through a terminal block and is rated for an operating temperature of -25 ~ +75 °C.
