The 233 Voltage Monitoring Relay senses voltage level in single
phase AC and DC circuits. Sensed voltage also serves as supply
voltage. Two independent levels of voltage (upper and lower) can
be set.
The 233 has an active output during normal operation and turns off
when a fault is sensed. Loss of supply voltage therefore is a
recognized fault.
Built-in hysteresis eliminates chattering at the transition point.
SPDT (Form C) contacts allow various connection options. Red and
green LED indicators allow quick identification of various fault
conditions.
