Monitoring Relays

When you need a relay that responds to specific electrical conditions, these monitoring relays are the solution.

Current Sensing

If the current is too low or too high, these current sensing relays will prevent process control issues and damage to equipment. They also have an adjustable time delay. Use them to monitor conditions such as heater or lamp load status and locked rotors in material handling equipment and generator control. All are solid-state relays.

SPST NO, 2 Terminals

0.1 sec — 10 sec Min/Max Time Delay

SPDT, 5 Terminals

0.5 sec — 50 sec Min/Max Time Delay

Voltage Sensing

Monitor voltage status in single-phase circuits with these relays to avoid damage to equipment and loss of power. These voltage-sensing relays shut down after voltage status has dropped or spiked for a preset amount of time in the case of a short temporary change that would not harm the equipment or circuit.

SPDT Configuration — DIN Rail Mount

0.1 sec — 10 sec Min/Max Time Delay

Phase Monitoring

Reduce harm to motors and machinery with phase monitoring relays. They prevent phase reversal, loss, and imbalance as well as voltage changes due to malfunctions in other components such as contacts, wires, and fuses.

Three Phase — SPDT Configuration

Safety Monitoring

Sensors on these safety monitoring relays check for malfunctions in automation and manufacturing equipment such as emergency stops, door switches, engine data management systems, interlock sensors, and light-curtain safety devices. The number of devices monitored matches the number of inputs for the relay.

24V AC/DC Supply Voltage

24V DC Supply Voltage

120V AC Supply Voltage

Force Guided

These force-guided relays function through force on the relay arm to help ensure that sticky contacts are moved into place. These are for use in safety applications such as emergency stops, door switches, engine data management systems, interlock sensors, and light-curtain safety devices.

Single Phase — DIN Rail Mount
