**Product Description:**

The TXM1.6RL module provides six electrically isolated relay outputs for switching AC or DC loads. The relay contacts are dry contacts, allowing connection to different potential groups without requiring a common reference voltage. This makes the module highly versatile for controlling various actuators such as contactors, solenoid valves, indicators, and small motors.

The module is designed for mounting on a standard ET 200SP BaseUnit, which handles the connection to the field wiring and provides the system power. It features a diagnostic LED for channel status and module fault indication. The
