Open Heat Detectors

Tell Tale Jr. are new Open Heat Detectors designed to indicate an open heater or other resistive load. LED or solid state switch models are available for various applications.

These models provide appropriate power supply to satisfy applications that send heater data to a PLC or computer.

The LED model lights up when current is flowing in the circuit. If current stops flowing the LED turns off.

Solid state switch models provide either a logic output for DC applications or a triac output for AC applications. Self powered and does not use power from monitored load.
