Dual Output Plug-in Signal Conditioners W-UNIT

THERMOCOUPLE TRANSMITTER

(field-programmable)

Functions & Features

• Accepting direct input from a thermocouple and providing

standard process signal

• Micro-processor based

• Field-programmable T/C type and temperature range

• Linearization

• Burnout protection

• High accuracy cold junction compensation

• Isolation up to 2000 V AC

• Loop testing via handheld programmer PU-2x

• High-density mounting

Typical Applications

• Ideal for quick spare part

• 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

MODEL: WJT–[1][2][3]–[4][5]

ORDERING INFORMATION

• Code number: WJT-[1][2][3]-[4][5]

Specify a code from below for each of [1] through [5].

(e.g. WJT-2AA-B/BL/Q)

• Temperature range (e.g. 0 – 800°C)

K thermocouple setting will be used if the input code is not

specified.

• Special output ranges (For codes Z & 0)

• Specify the specification for option code /Q

(e.g. /C01/S01)

Note: When the user requires a current and a voltage

output, specify the current to be the Output 1 which allows

a greater load.
