FAQ

Question?
Can the plug-in relay (part no. 2961192) be replaced separately from the base?

Answer

Yes, this is a key feature of the PLC-INTERFACE series. The miniature relay can be unplugged from the PLC-BSC base and replaced individually, which simplifies maintenance and reduces costs.

Question?
What is the difference between the PLC-BSC and PLC-RSC series from Phoenix Contact?

Answer

The PLC-BSC series refers to the 'Basic' terminal block/base, while the PLC-RSC series typically denotes the complete pre-assembled 'Relay' module (base + relay). This unit consists of a PLC-BSC base with a compatible relay installed.

Question?
What type of screwdriver is needed for the screw terminals on this module?

Answer

The PLC-BSC-24DC/21-21 uses standard screw terminals. A small flat-head or slotted screwdriver with a blade width of approximately 2.5mm to 3.5mm is recommended for secure wire termination.
