D1073
- SIL 2 Temperature Signal Converter and Trip Amplifiers
G.M. International ISM0019-13
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.
Function:
1 channel I.S. input from mV, thermocouples, 3-4 wires resistance thermometers, transmitting potentiometers, provides 3 port isolation (input/output/supply) and current
(source mode) or voltage output signal. The programmable RTD line resistance compensation allows the use of 2 wires RTDs or error compensation for 3-4 wires RTDs.
Reference junction compensation can be automatic, with option 91, or fixed by software setting. In addition it provides two SPST relay alarm contacts with adjustable alarm trip point.
Signalling LEDs:
Power supply indication (green), burnout (red), alarm A (red), alarm B (red).
Configurability:
Totally software configurable, no jumpers or switches, input sensor, connection mode, burnout operation, mA or V output signal, alarm trip point, high, low, low-startup
or burnout alarm mode, NE/ND relay operation, hysteresis, delay time, by GM Pocket Portable Configurator PPC1090, powered by the unit or configured by PC via RS-232 serial line
with PPC1092 Adapter and SWC1090 Configurator software. A 16 characters tag can be inserted using SWC1090 Configurator software.
