VOLTAGE LEVEL SENSOR / INTERLOCK

Standard Model
for Fixed Trip Setting


voltagelevel2

Trip point set with external selected resistor(s) for: 

Set point repeatability 1% AC, 0.1% DC.

Temperature range -10°C to 55°C.

Basic reset time 100 milliseconds.

Over-voltage withstand 200V to 2500V PK transient impulse, depending on model. 

Output drives average 115V relay coil. Internal trip basic input resistance 78kΩ, 55V PK. Add external resistor for external trip sensing and omit R2.  0.7mA DC or AC PK into 78kΩ basic input to develop 55V DC or 39V RMS AC sense voltage across 78kΩ, ½ watt input resistor to trip. Sense voltages 1V to 200V available.

For adjustable trip, hysteresis, delay, isolated input, see Deluxe Model.

Note 
For internal 115V AC line sensing, select resistance of R2 for desired operating point. ie...
