Functional Features

High Reliability

The TMR architecture processes and verifies each digital input signal through three independent channels, using a "2-out-of-3" voting mechanism to eliminate single-point failures and prevent false trips.

High-Density Input

Provides 40 digital input channels for connecting up to 40 field digital input devices (e.g., switches and sensors), with each channel accurately reading 24Vdc signals.
