CM relay - 7 contacts and 2 gold contacts
Informatie
Description
The CM relay is designed for combined power & dry circuit applications in diesel locomotives.
Part number CM 045 72 37 S M is rated for 72 VDC nominal voltage and is configured with 4 N/C and 5 N/O double break contacts. Two of them (1 N/C & 1 N/O) are gold bifurcated contacts (dry circuit). All other contacts are in silver.
On specific request, to provide for the large voltage drop that occurs during start-up of a diesel engine, the non-dropout voltage can be adjusted to a low value of 24 VDC for a 72 VDC nominal coil voltage.
The CM relays is pluggable in the COR NJ socket.
Application
The CM relay is designed for both power levels and low level signals are being switched for general purpose heavy duty applications such as lighting, pumps and fans, as standard Weld no transfer design for safety critical applications such as door control, emergency brake failure, interlocking traction and breaking with a gold bifurcated contact for dry circuit signal information.
