Full Description

Out-of-lock Relay 1 Form C SPDT [1088B], as installed on rear of chassis.

Option 19 for the Model 1088B Satellite-Controlled Clock incorporates a fail-safe single-pole, double-throw (SPDT) relay into the Out-of-Lock function already available in the standard instrument. Relay activation is subject to the same user-configurable delay as the standard output; thus it will occur at the same moment as the logic-level Out-of-Lock signal from the rear panel (if so configured). Normally-open, normally-closed, and common connections are available at screw terminals on the rear panel. Available on the Model 1088B, Slot B.
