VOLTAGE CONTROL RELAY
UL listed CSA recognized
• AC or DC Voltage Control
• Manual or Automatic Operation
• Adjustable Threshold
• 5 to 50% Hysteresis Range
• LED Relay Status Indicator
1. AC/DC voltage control without latching:
2
The output relay is energized when the voltage (AC peak voltage)
exceeds the selected threshold. It de-energizes when the voltage
falls below the hysteresis setting (5 to 50%) or when supply breaks.
The hysteresis is controlled by a potentiometer and its selection does
not change the chosen threshold.

2. AC/DC voltage control with latching:
The output relay is energized when the voltage reaches the selected
threshold and stays latched in this position. The contact between ter-
minal B1 and M (or 8 or 9) should be opened or the input power of
the device interrupted to reset.
