Signal Isolators

Product Description

Signal Isolators are used for isolating sensitive equipment like PLC, DCS, Data Loggers / Scanners from harmful transients, ground-loop currents riding on signals coming from field. Similarly, they block high voltages and high currents going to field when fault occurs in control room equipment. This is particularly important for applications in hazardous area, where current and voltage levels of equipment in the field must be limited.

Salient Features

  • Isolation level of 1000 V. A.C. + D.C. peak
  • Microprocessor based linearization & CJC for RTD & T/C
  • User settable measuring ranges
  • Optional models for 3 port or cost-effective 2 port isolation
  • Compact (22.5 mm width) DIN Rail mounting
  • Diagnostic indications for open loop, healthiness of microcontroller

Product Applications

  • Interfacing of RTD, Thermocouples to PLCs, DCS
  • Interfacing of PLC, DCS to VFDs
  • Isolation of ground loop currents of analog signals
  • Duplication of signals for connecting to multiple equipment
