The SWE-94-U is a simple and low cost, digital, 4-digit indicator with a single current input.

The meter is equipped with one current input (0/4-20mA), two voltage inputs (0-10V and 0-150 mV), one RTD input (Pt 100/500/1000) and one TC input (thermocouple: K, S, J, T, N, R, B, E). Temperature of cold ends is compensated automatically. RTD and TC inputs are fully linearised. Only one input can be used at a time.

With the SWE-94-U the user can select a characteristic conversion of several kinds: linear, square, square root, user defined.

The device is equipped with RS-485 / Modbus RTU communication interface. The device can be configured via IR remote controller or optionally by PC free S-Config software, via RS-485 interface. Over communication interface RS-485 this enables data transmission in any monitoring system equipped with Modbus RTU protocol. Easy assembling, precision and reliability are the basic trumps of SWE-94-U indicators.

IR remote controller is not a part of the SWE-94-U and must be ordered separately.
