General Description:

The single channel DIN Rail Temperature Signal Converter and Trip Amplifier D1073S

accepts a low level dc signal from millivolt, thermocouple or RTD temperature sensor,

located in Hazardous Area, and converts, with isolation, the signal to drive a Safe Area

load. Output signal can be direct or reverse.

Two independent Alarm Trip Amplifiers are also provided. Each alarm energizes, or

de-energizes, an SPST relay for high, low, low-startup or burnout alarm functions.

The two alarm relays trip points are settable over the entire input signal range.
