SPT-86L module is the insulated temperature and voltage to current in the 4-20 mA standard transmitter, and has possibility of data reading via RS-485 interface.

It has one input: Pt 100/500/1000, thermocouples K/S/J/T/N/R/B/E, 0-60 / 0-75 / 0-100 / 0-150 mV and one passive current output 4-20 mA.

During the measurement one type of input can be used at a time only.

The measurement inputs have full linearization of characteristics and automatic compensation of the cold junction temperature in the thermocouple mode.

Pt mode handles three methods of connection: 2-, 3- and 4-wire.

For the milivoltage input user can choose between linear, square, square root or user defined characteristics.

In the basic configuration the measurement, after being processed, is given to the current output, but current output can be also controlled directly thru serial interface.

For configuring and data reading RS-485: Modbus RTU interface is used.

The device parameters can be set by the S-Config software, directly from PC level.

Every unit can be factory pre-configured on request.
