SIL 2 LOAD CELL/STRAIN GAUGE BRIDGE ISOLATING CONVERTER DESCRIPTION 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 61511) 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 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, 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.
