FAQ

Question?
Is this a complete relay module or just the base?

Answer

This is a complete module, consisting of the PLC-BSC-12DC/21 base (Part No. 2966896) and the pluggable miniature relay REL-MR-12DC/21 (Part No. 2961150).

Question?
What is the maximum wire size for the screw terminals?

Answer

The screw terminals on the PLC-BSC-12DC/21 base can accommodate a wire cross-section from 0.14 mm squared to 2.5 mm squared (AWG 26 to 14).

Question?
Can I replace the plug-in relay with a different voltage version?

Answer

No, the base PLC-BSC-12DC/21 is specifically designed for a 12V DC input coil voltage. You must use a compatible 12V DC relay like the included 2961150. Using a different voltage relay will not work and may damage the component.
