Description

The BTCT226 is a loop powered isolating thermocouple transmitter that offers an economical solution combining compactness with accuracy and flexibility. The BTCT226 is ideal for field enclosures or as a space saver in larger control cabinets. Standard output is 4 – 20mA with a minimum supply voltage of 8V. This enables the BTCT226 to be used in 12V battery supply systems or in automotive applications. Other factory set output configurations are 10 – 50mA loop powered and various 3-wire outputs. Double surge protection is standard with all Series 200 loop powered transmitters to prevent failure due to spikes induced by DC switched inductive loads. The BTCT226 can accept any type of thermocouple input.The thermocouple conditioning features:

 Automatic cold junction compensation.

 Front-end zero suppression via 15 turn potentiometer.

 Configurable upscale or downscale burnout.

 A linearised version is available.

Final calibration is trimmed using the front accessible zero and span 15- turn trim adjustments. A front mounted L.E.D. and a test socket verify module function and assist in calibration checks without disconnection of output wires.
