Frequently Asked Questions (FAQ)
Q1: What does "TRZ" mean in the model name?
A: TRZ indicates that this TERMSERIES relay base uses tension clamp (spring-loaded) terminals for wire connection. The TRS variant uses standard screw terminals.
Q2: Can the relay insert be replaced separately?
A: Yes, this is a complete module consisting of a plug-in socket base and a removable miniature relay (such as the Weidmüller RSS113024).
Q3: Does this module require an external freewheeling diode?
A: No, the base has integrated free-wheel diode and reverse polarity protection built into its internal circuit.
Q4: How do I read the contact wiring schematic printed on the side?
11 (COM): Common terminal
14 (NO): Normally Open contact
12 (NC): Normally Closed contact
A1 (+) & A2 (-): 24 V DC coil supply inputs
