The weight indicator IW-320

The weight indicator IW-320

The weight indicator IW-320 is intended for transformation of input analogue signals from tensoresistive transmitters and indication of weighing results in composition of weight-measuring devices and systems of monitoring and control.

Features:

- two measuring weight ports with possibility of parallel operation;

- indication of weight from two ports separately and (or) totally;

- simple calibration by exemplary weights, and with use of values mV/V of the transmitters;

- six- or four wire connection of transmitters;

- a selected range of input signals;

- modes of filtration, adjusted by the user, in the port of weight measuring;

- indication of instability of weight indications;

- indication of scales overloading;

- data transmission to peripherals by the serial interface with use of the protocol ModBus or by the protocol of the firm "Sweda";

- two-standard (RS-485 or RS-232), selected by the user, galvanically disentangled serial interface;

- use of wireless data transmission by means of the portable modem;

- connection of a portable doubling board for indication of weighing results;

- adjustable brightness of the indicator;

- possibility of operation from the autonomous power supply (accumulator) with possibility of additional charge of the accumulator at operation from the mains supply source;

- adjustable automatic shut-down of the gear on time;

- a support arm for gear fixing.
