Product Information
Extended Description
1SVR405618R0100 ABB: The CR-M024AC4LG pluggable interface relay is a miniature relay with gold-plated contacts, which is to be plugged into a suitable ABB CR-M socket. Plugged into a socket, the combination of relay and socket may be seemlessly snap-on mounted onto a DIN Rail.This relay operates with a 24 V AC rated control supply voltage and has a 4 c/o (SPDT) output with contacts rated at 250 V / 6A, enabling the possibility of switching multiple circuits with a single input signal. The relay has an integrated test button which is used for the manual actuation of the relay by locking it's output contacts. The test button facilitates easy testing and commissioning. The relay also has an integrated LED, which provides the visual indication of the energization of the relay coil. Furthermore, the gold-plated contacts ensure contact reliability particularly necessary in applications where small currents and loads are to be switched. Standard sockets, logic sockets, pluggable function modules, holders and markers are available as accessories. Standard sockets, logical sockets, pluggable function modules, holder and marker are available as accessories.
