Carlo Gavazzi’s DTA7 Series of Motor Thermistor Relays are capable of monitoring the temperature of up to six motors (via thermistors on the internal windings). This type of monitoring and control prevents false alarms, which may cause interruptions in production and machine downtime.
There are also improvements from the prior design of the motor relays, such as universal power supply, which reduces the available part numbers choices by 67 percent, and a bi-color LED, which, through different colors and blinking statuses, provides diagnostics. One or two output versions are available to facilitate control of the motor(s), with two output devices having the ability to control other auxiliary devices, such as an alarm indicator lamp, PC, or PLC.
