AE-OPT-376 provides a relay output for some versions of the AE series large displays. AE series functions that use the relay output option are count up elapsed timers and count down elapsed timers. The relay activates for two seconds when the elapsed time reaches zero. The relay activates for two seconds when the time of day goes through midnight. These time of day and elapsed timer functions are included in the standard multi-function clock/timers, stand-alone up counting or down counting elapsed timers, and the clock/ timer functions included with the RS232 Option 354. Labeled, and color coded, pigtail lead wires for the relay contacts are provided at the back panel of most models. Others may have terminal block wiring.
