Remote inhibit
Remote sense
TTL logic signal goes high 100-500 msec after 5 V output; it
goes low at least 4 msec before loss of regulation
Requires an external TTL Signal to inhibit outputs
Compensates for 0.5 V lead drop minimum, will operate without remote sense connected. Reverse connection protection.
