PR Electronics 9116A – Universal Converter

Advanced features

  • Configuration and monitoring using a detachable display front (PR 45xx); includes process calibration, signal and relay simulation.
  • Advanced relay configuration options, such as setpoint, window, delay, sensor error indication, and power monitoring.
  • Capability to copy configurations from one device to others of the same type via the display front.
  • Thermocouple (TC) inputs with internal or external Cold Junction Compensation (CJC) for higher accuracy.
  • Active or passive mA output available via the same two terminals.

Applications:

  • Can be mounted in safe areas or in Zone 2 / Class I, Division 2, Groups A, B, C, D.
  • Suitable for converting and scaling temperature, voltage, potentiometer, and linear resistance signals.
  • Functions as a power supply and signal isolator for 2-wire transmitters.
  • Monitors error events and cable breakage via individual status relays and/or a collective electronic signal through the power rail.
  • Designed, developed, and certified for use in SIL 2 applications according to IEC 61508 requirements.
  • Suitable for use in systems up to Performance Level “d” as per ISO-13849.

Technical Characteristics:

  • One green and one red front LED indicate operational status and malfunction. A yellow LED indicates relay status.
  • Provides 2.6 kVAC galvanic isolation between input, output, and supply.

Mounting:

  • Can be mounted vertically or horizontally without any distance between adjacent units.
