Rack-mounted DCS Signal Conditioners 18-RACK

OUTPUT 1

Voltage

6: 1 – 5 V DC (Load resistance 2000 Ω min.)

THERMOCOUPLE CONVERTER

Functions & Features

• Accepting direct input from a thermocouple and providing

two standard process signals

[2] OUTPUT 2

Current

• 5-segment linearization

A: 4 – 20 mA DC (Load resistance 600 Ω max.)

Voltage

• Burnout protection

• High-accuracy cold junction compensation

• Second channel output available at the front terminals

and at the Standard Rack connector

6: 1 – 5 V DC (Load resistance 2000 Ω min.)

POWER INPUT

DC Power

Typical Applications

R: 24 V DC

• High-accuracy cold junction compensation benefits narrow

span measurements

(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)

• 0.1 μA burnout sensing enables long distance

transmission with minimum offset drifts

• Electric furnace (isolation)

[3] OPTIONS

Burnout

blank: Upscale burnout

/BL: Downscale burnout

/BN: No burnout

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

with a recorder
