PLC Digital I/O Expansion Module 8DI 8DO for B1 series

The FATEK B1-16XY(T) is a 16-point digital I/O extension module designed for the B1 series PLC, including the B1-20M(T). Providing 8 digital inputs and 8 transistor outputs, it delivers cost-effective system scaling for factory automation and machine control applications. Built with 500VAC optical isolation across all channels and flexible SINK/SOURCE input wiring, this module ensures reliable signal integrity and noise immunity when interfacing with industrial field sensors and actuators.

• Balanced 16-Point I/O Expansion: Adds 8 digital inputs and 8 transistor digital outputs to scale up the I/O capacity of B1 series main units.
• SINK/SOURCE Input Wiring: Accepts 24VDC ±10% signals (4.5mA max current) with wiring-selectable SINK or SOURCE polarity via the internal S/S common terminal.
• Dependable NPN Transistor Outputs: Delivers 8 NPN outputs rated for 0.5A maximum load current for both resistive and inductive loads.
• Optical Isolation: Features 500VAC optical isolation (1 minute) across all digital inputs and outputs to shield main CPU logic from electrical noise and voltage transients.
• 5–30VDC Output Range: Supports field load voltages from 5VDC to 30VDC, offering broad compatibility with industrial solenoids, indicator lamps, and external relays.
• System Integration: Serves as a direct extension module for the B1-20M(T), enabling DIN-rail installation.
