How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The Siemens 6ES7194-4AP00-0AA0 is a terminal connection module for the SIMATIC ET 200pro CPU 151xPRO(F)-2 PN, combining three M12 ports and two 7/8-inch ports to wire two PROFINET lines plus 24 V power. Each supply rail (1L+, 2L+) delivers up to 8 A, with an internal 2L+-to-1L+ transfer capped at 5 A.
Use this CPU terminal module when wiring the ET 200pro head end directly; it is the only connection module in this range built for the CPU 151xPRO(F)-2 PN rather than an IM interface module, and its dual-PROFINET M12 pair supports line or ring topologies at the station head. The 5 A internal transfer limit on 1L+ matters when the CPU draws power from the same feed as downstream modules.
