Carlo Gavazzi is pleased to announce their new DTA7 Series of Motor Thermistor Relays. They 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 expensive machine downtime.
There are also numerous improvements from our prior design, such as universal power supply (which reduces the available part numbers choices by 67%) and a bi-color LED which, through different colors and blinking statuses, provides diagnostics, i.e. Power ON, PTC failure(s), Alarm and the ready to RESET state.
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.
The Carlo Gavazzi DTA7 Series are useful in most applications where motors are used, especially where overloads are frequent and may cause motor damage, i.e. pumping stations in water treatment, conveyors in materials handling and chillers in HVAC systems.
Main features of the DTA7 Series include:
35.5 mm Mini DIN housing, with screw terminals
1 SPDT (DTA71) or 2 SPDT relay output (DTA72)
Relay contacts are NEMA B300 rated @ 240 VAC
Output 1 is DE-ENERGIZED on alarm (DTA71/DTA72)
(Optional) Output 2 ENERGIZED on alarm (DTA72)
