Page 2: General Technical Specifications
Installation Manual WTS3 Series II WTS3 – GENERAL DESCRIPTION WTS3 weight conditioner and transmitter has been developed to interface strain gage transducers with industrial automation systems (such as PLC, computers etc..). The board supplies up to 4 load cell (350 ohm) amplifies the load cell signal and perform 2 different analog outputs: a 0 - 10 V and a current output 0 - 20 mA or 4 - 20 mA (Factory selected). -

Installation Manual WTS3 Series II APPLICATION AND PRINCIPLE OF OPERATION The module WTS3 is an amplifier for strain gage. This amplifier offers a simple and valid procedure for calibration using rotary switches and trim-pots. The supply voltage of the transducer is 10 Vdc with the possibility of connection to 4 or 6 wires. With six-wire connection, making a correct compensation of the voltage drop on the connecting cables, for a calibration easier and a higher accuracy. - Page 4 Installation Manual WTS3 Series II SET UP : SWITCH SW3 SELECTION ELECTION OF THE CURRENT RANGE Select switch SW3-5 according to the following table to select the output current range 4 - 20 mA or 0 - 20 mA : SW3-5 Output signal range 4 - 20 mA...
