The NATIONAL TIME D900-ISO provides line to line short circuit fault isolation on the DigiComm™ Loop or 24VDC riser. The Isolator can be configured for style 4 or 7 (class A/B) operation. The Isolator provides a LED indication on activation. In style 4 operation, devices upstream of the activated isolator will operate as intended. In style 7 operation, devices upstream of the first activated isolator and downstream of the second activated isolator will operate as intended. The isolator restores to normal operation upon restoration of the fault condition. No system reset is required. The isolator mounts to a 4" diameter isolator base.
