Description
The Dual Output Trip Alarm provides two potential free contact outputs which switch at preset levels. Both levels can be set using the trimpots on the front of the unit or by injecting desired values and capturing.
The switching points can be configured to be either active on rising or falling levels. Each relay output can be separately configured. An adjustable amount of hysteresis between the switch on and switch off reduces relay chatter with noisy signals.
