The MCR-SWS can be utilized as an analog setpoint alarm or as a simple, on/off process controller. The MCR-SWS has setpoint adjustment and alarm band hysteresis adjustment.
The alarm setpoint and hysterisis are adjusted by potentiometers. Relay status is indicated by a LED and PNP transistor. The alarm hysteresis is full scale adjustable. Three transistor level switches indicate over/under and relay status. Example: A 0-10 V MCR-SWS, can be adjusted to a setpoint of 5 V and a hysteresis of 6 V. The PNP (A) output and indicator would be active until 2 V was reached, at which point the PNP (B) output would become active. The relay, PNP (C) output and indicator would energize upon an 8 V signal level. The relay contact will denergize upon reaching the lower set hysteresis. The PNP transistors are capable of a 100 mA max current.
