D5264S

Описание

The single channel DIN Rail Load Cell/Strain Gauge Bridge Isolating Converter D5264S module is a unit suitable for applications requiring SIL 2 level (according to IEC 61508:2010) in safety related systems for high risk industries.

The unit acts as a galvanically isolated interface installed between a PLC/DCS in Safe Area and a load cell (or a group of load cells) in Hazardous Area. Up to four 350 ? load cells; or five 450 ? load cells; or ten 1000 ? 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; providing both current source and sink capabilities. The module is also provided with PhotoMOS alarm output.

A modbus output is also provided to interface the PLC/DCS using digital communication.

Mounting on standard DIN-Rail; with or without Power Bus; in Safe Area or in Zone 2.
