Product description
Intelligent Input/Output module PFAP401-NC2C PICO PRO D4 with four opto-isolated digital inputs and four opto-isolated transistor digital outputs, each with separate commons. Inputs include a programmable debounce filter and are suitable for pulse counting and remote status signalling. Outputs are rated 27 VDC / 27 mA (DIN 43864) and can be used for local alarms or controlled remotely via Modbus. Up to eight configurable alarms can drive outputs and/or set status registers on Modbus.

Operation and communication
LED indicators: power, status and RS485 communication. Communication protocol: Modbus-RTU over RS485. Firmware remotely upgradeable. DIN-rail mounting, 4-module width. Power supply: 230–240 VAC.

Typical applications

• Pulse counting from flowmeters, sensors or external contacts
• Remote status monitoring of field devices
• Local alarm signalling and actuator control via digital outputs
• Integration into supervisory systems via Modbus-RTU
