Why choose it

This module provides galvanic isolation between control and load circuits, protecting sensitive PLC outputs from voltage spikes and noise. The MOSFET output offers fast, wear-free switching for DC loads, and built-in protections extend service life in demanding environments.

Ideal use cases

• Interfacing PLC digital outputs to solenoids, valves, or DC motors
• Switching resistive or inductive DC loads in automation systems
• Expanding output capacity in control cabinets

Good to know

The module belongs to the Finder MasterINTERFACE series and is designed for DIN rail mounting. Screw terminals provide secure wiring. The LED indicates input status for quick diagnostics.
