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.

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.

Automatic Calibration:

Automatic calibration can be accomplished in the field without disconnecting the unit.

Function:

1 channel I.S. input from strain gauge signals, provides 3 port isolation

(input/output/supply) and current (source or sink mode) or voltage output signal.

Modbus output is also provided to interface digital device.

Signalling LED:

Power supply indication (green).

Configurability:

Totally software configurable, no jumpers or switches, input calibration, mA or V output

signal by GM Pocket Portable Configurator PPC1090, powered by the unit or

configured by PC via RS-232 serial line with PPC1092 Adapter and SWC1090

Configurator software. To operate PPC1090 or PPC1092 refer to instruction manual.

A 16 characters tag can be inserted using the configuration software.

EMC:

Fully compliant with CE marking applicable requirements.
