D5263S
SIL 2 Load Cell/Strain Gauge Bridge Isolating Repeater
Description
The single channel DIN Rail Load Cell/Strain Gauge Bridge Isolating Repeater D5263S 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 transparent galvanic isolated interface installed between a weighing indicator in Safe Area and a load cell (or group of load cells) in Hazardous Area; it appears at the terminals of the indicator as a single load cell equivalent to the one in the field.
It provides a fully floating power supply voltage with remote sensing capability to load cell located in Hazardous Area and repeats, while isolating, the mV signal output to drive a load in Safe Area depending on the host system reference voltage.
Up to four 350 Ω load cells, or five 450 Ω load cells, or ten 1000 Ω load cells can be connected in parallel.
The Voltage reference (Safe Area side) is set as an external supply.
Mounting on standard DIN-Rail, with or without Power Bus, in Safe Area or in Zone 2.
