RELAY CONTROL SYSTEM: System Description: Description
IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input signals from various sensors and the request signals received from control units via CAN communication.
NOTE:
To prevent to the parts, IPDM E/R integrated relays cannot be removed.
