Digital I/O module PFAPT0C-QCHG PICO PRO SIO

ModbusRS-485Modbus RTU

Product overview
Intelligent input/output and sensor device with 2 opto-isolated digital inputs, 6 opto-isolated transistor digital outputs with separate commons, SIO Bus expansion and 2 relay outputs with changeover contacts for driving loads up to 250 VAC / 2 A (resistive). Digital inputs include a programmable debounce filter (suitable for pulse counting or remote status indication). Digital outputs are rated 27 VDC / 27 mA (DIN 43864) and configurable for internal alarms or remote control via Modbus. I/O circuits are self-powered and do not require an external supply. The SIO Bus supports integration of additional I/O modules and environmental sensors via Milli Pro devices. Up to eight configurable alarms can drive digital outputs and/or set Modbus status registers.

Communications and firmware
Communication protocol: Modbus-RTU over RS485. Firmware remotely upgradeable.

Power and enclosure
Supply voltage: 85–265 VAC / 100–374 VDC. Optional 12 VDC backup via external UPS. Available auxiliary output: Vout 12 VDC. Enclosure: grey. Dimensions: 150 × 45 × 100 mm.

Typical applications

• External pulse counting
• Remote status indication
• Driving loads via relays (up to 250 VAC, 2 A resistive)
• Integration of additional I/O and environmental sensors via SIO Bus
