Safety I/O-Modules

The safety-input bus terminals are a digital input terminal for sensors with potential-free contacts for 24 V DC. This module has four/eight fail-safe inputs and meets the requirements of IEC 61508 SIL 3 and EN 954 Cat. 4.

The safety-output bus terminals are a digital output terminal with four/eight channels. It switches 24V DC motors with up to 2A total current. If the bus terminal detects an error, it switches off automatically (fail stop) and thus meets the requirements of IEC 61508 SIL 3 and EN 954 Cat. 4.
