The Undervoltage Monitor With Reset (acknowledgment) has outputs for a signal, buzzer or other indicators. It can be used to turn on/off acoustic or optical warning signals when the input voltage drops below/exceeds a defined voltage level. When the input voltage applied to terminal 15 drops below the defined threshold voltage outputs 87, 87a, and C are turned on. Output 87 can be switched off again via reset input x (acknowledgement) while outputs 87a and C remain on. When the input voltage on terminal 15 exceeds the defined threshold voltage all outputs are switched off. Custom threshold voltages are available on request. Please refer to the chapter housing and base plates for additional housing options.
