D1073S
1 Ch, Universal Temp. Converter and Trip Amplifier, SIL 2
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.Features
