PR9116B, Universal converter

 
  • * Input for resistance sensor (RTD), thermocouples (TC), Ohm, potentiometer, mA and V
  • * Supply for 2-wire transmitters
  • * Active / passive mA output and relay output
  • * Can be supplied separately or installed on power rail, PR type 9400
  • * SIL 2-certified via Full Assessment

Advanced features

  • * Configuration and monitoring by way of detachable display front (PR 4501); process calibration, signal and relay simulation.
  • * Advanced relay configuration, e.g. setpoint, window, delay, sensor error indication and power monitoring.
  • * Copying of the configuration from one device to thers of the same type via PR4501.
  • * Reduced Uo Ex data < 8.3 V for active input signals.
  • * TC inputs with internal CJC or external CJC for higher accuracy.
  • * The device automatically detects whether it must supply an active or a passive current signal.

Application

  • * 9116B can me mounted in the safe are and in zone 2 / cl. 1 div. 2 and receive signals from zone 0, 1, 2 and zone 20, 21, 22 including M1 / Class I/II/III, Div. 1, Gr A-G.
  • * Conversion and scalling of temperature, voltage, potentiometer and linear resistance signals.
  • * Power supply and signal isolator for 2-wire transmitters.
  • * Monitoring of error events and cable breakage via the individual status relay and / or a collective electronic signal via the power rail.
  • * The 9116 has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.

Technical characteristics

  • * 1 green and 1 red front LED indicate operation status and malfunction. 1 yellow LED indicates relay status.
  • * 2.6 kVAC galvanic isolation between input, output and supply.
