Rack-mounted DCS Signal Conditioners 18K-RACK

THERMOCOUPLE CONVERTER

Functions & Features

• For thermocouple inputs

• 5-segment linearization, isolation and burnout protection

(outputs scale out when disconnected) included

• High-accuracy cold junction compensation

• Module can be retracted without removing wiring for an

insulation test

Typical Applications

• High-accuracy cold junction compensation benefits narrow

span measurements

• 0.1 μA burnout sensing enables long distance

transmission with minimum offset drifts

• Electric furnace (isolation)

• No burnout type can connect to a single T/C in parallel

with a recorder
