4-20mA Loadcell Conversion

4-20mA assembly can normally be installed directly in the loadcell

Directly connect load cells to a PLC or to a computer with a 4 to 20 ma interface circuit as seen below. Ideal for industrial non legal for trade application

Our precision current output converter is designed to transmit analog 4-to-20 ma signals over an industry standard current loop.

Specifications

Temperature range -40 to +85 deg. C

Input voltage 7.5 to 36 volts

RS232 Interface

The D5251 converts up to four 4-20mA analog DC current signals to digital information, linearizes the digital data and communicates the values to a host computer or PLC.

The data values are transmitted to a host computer via an RS-232 or RS-485
serial communications link using an ASCII protocol.
