1~DESCRIPTION.
The device is a “smart” in-head transmitter that accepts thermocouple temperature
sensors and converts sensor output over a configured range to a standard industrial
(4 to 20) mA transmission signal.
PC configuration allows the user to select thermocouple type, range, units and
burnout direction, without requiring calibration equipment. Configuration is performed
quickly using our USB port-driven configurator.
Calibration setup may be saved as a file on the PC for later use. If required the
desired range can be specified at the time of order, removing the need for user
configuration.
2~RECEIVING AND UNPACKING.
Please inspect the packaging and instrument thoroughly for any signs of transit
damage. If the instrument has been damaged, please notify your supplier
immediately.
3~SPECIFICATION.
Refer to data sheet for full specification.

Centres
Mounting holes: two holes 5.5 mm diameter, 33 mm centres.
Centre hole sensor wire entry 4 mm.
4.1~MECHANICAL.
The unit is mounted using two 5.5 mm holes, on standard 33 mm fixing centres and will
fit a DIN standard termination head. The unit must be installed with adequate protection
from moisture and corrosive atmospheres.
Care must be taken to ensure the unit is located so the ambient temperature does not
exceed the specified operating temperature.
4.2~ELECTRICAL.
Electrical connections to the transmitter are made to the screw terminal provided on the
top face. The transmitter is protected against reverse connection and over-voltage. If
no sensor (input) connection is made, the transmitter will go into either up or down
scale output current, depending on configuration setting.
TURN OFF SUPPLY BEFORE WORKING ON ANY ELECTRICAL CONNECTION
Input sensor connections.
Thermocouple inputs must use correct compensation cable.
Sensor connections are as follows: to maintain BS EN61326 compliance, sensor wires
must be less than 3 metres. All sensor connections must be isolated from ground.

(4 to 20) mA Loop connections.
Ensure all other aspects of the installation comply with the requirements of this
document. To maintain CE compliance, the (4 to 20) mA current loop must be tied to a
local earth at one point; this is normally at the power supply.
Use twisted pair or screened cables for cable lengths greater than 30 metres. Maximum
cable length 1000 metres.
5~USER CONFIGURATION.
IMPORTANT
READ COMPLETE SECTION BEFORE ATTEMPTING CONFIGURATION.
IMPORTANT
Do not attempt to configure the unit when connected to a loop supply.
A USB configuration module is required for connecting the unit to the PC. Refer to your
supplier for details.
