Product Information
STANDARD FEATURES - Can be placed at any location on SLC loop. - Checks the line for short circuit at power up. If the line is normal, the relay will be returned on. If a line short is detected, the relay remains open. - Indication of short circuit by a yellow LED OPERATION * Class A Configuration Wiring: The DCP-SCI short circuit isolator should be located between any devices on the SLC loop. In the event of a short on the SLC loop, the two adjacent isolators (closest isolators to the left and right of the shorted section) will activate and their respective LED indicators will be turned on. All devices between the active short circuit isolators will be dead. This will prevent entire loop failure. Upon removal of the short condition, the DCP-SCIs will automatically restore, the entire loop to the normal operating state. * Class B Configuration Wiring: The DCP-SCI short circuit isolator should be located between any devices on the SLC loop. In the event of a short on SLC loop, an isolator closest to the shorted section will activate and the LED will be turned on. All the devices beyond the shorted section will be disabled. Upon removal of the short condition, the DCP-SCI will automatically restore the entire loop to the normal operating state. For the best performance of DCP-SCI short circuit, use class A configuration.
