Analog I/O module PFAP401-RZ2C PICO PRO D4

ModbusRS-485serial

Product overview
The PICO PRO D4 PFAP401-RZ2C is an intelligent input/output and sensor module designed for monitoring and control applications. It features 4 configurable analog inputs and an SIO Bus for expanding digital/analog I/O and environmental sensors. Analog inputs accept -10 to 10 V (compatible with 0–10 V, 0–5 V, -5–5 V) and 4–20 mA signals using a 200 Ω resistor. The device communicates over Modbus-RTU via RS485, supports remote firmware upgrades and is DIN-rail mounted (4-module size). Power supply: 230–240 VAC.

Key features

• 4 configurable analog inputs
• SIO Bus for expandable I/O and environmental sensors (via Milli Pro devices)
• Analog input ranges: -10 to 10 V (compatible with 0–10 V, 0–5 V, -5–5 V)
• 4–20 mA support with 200 Ω resistor
• Up to 8 configurable alarms to drive digital outputs or set Modbus register states
• LED indicators: power, status, RS485 communication
• Communication: Modbus-RTU over RS485
• Remote firmware upgrade capability
• DIN-rail mounting, 4-module mechanical size
• Power supply: 230–240 VAC

Notes
Designed for integration into industrial monitoring and control systems. Expandability via the SIO Bus allows adding digital/analog I/O and environmental sensors after initial installation using Milli Pro devices. Ideal where Modbus-RTU communication and DIN-rail mounting are required.
