Sept. 15, 2025 – WAGO is introducing three functional safety I/O modules to be used with WAGO’s PFC controllers. These new 750 Series modules have four safe inputs along with either two safe outputs at 10 A/24 VDC, or four safe outputs at 2 A/24 VDC each. The power outputs operate in both bipolar (high-side/low-side switching) and unipolar (common potential on one side of the load) modes. The module monitors short circuits, cross circuits, and 24 V power supply from separate sources.
The modules contain internal logic that can be programmed with WAGO’s I/O-CHECK and Safety Editor software. Using these modules, safety-related applications up to SIL3/PLe can be implemented without the need for a safety PLC. These modules have been evaluated by UL in compliance with the UL/CSA 61010-1, UL/CSA 61010-2-201 and UL 121201, and CSA-C22.2 No. 213 standards.
