General Description:

The single channel DIN Rail Load Cell/Strain Gauge Bridge Isolating Converter D1064S

acts as a galvanically isolated interface installed between a PLC/DCS in Safe Area and

a load cell (or group of load cells) in Hazardous Area. Up to four 350 Ω load cells,

or five 450 Ω load cells, or ten 1000 Ω load cells can be connected in parallel.

It provides a fully floating power supply voltage with remote sensing capabilities to

load cells located in Hazardous Area and converts the mV signal from the load cell into

a 0/4-20 mA or 0/1-5 V or 0/2-10 V signal according to user desired range.

Output circuit provides both current source and sink capabilities.

Modbus output is also provided to interface PLC/DCS using digital communication.

Features:

SIL 2 according to IEC 61508:2010 (Route 2H) with
