PR Electronics 9116B – Universal Converter

Advanced features

  • Configuration and monitoring can be performed using a detachable display front (PR 45xx), allowing for process calibration, signal and relay simulation.
  • Advanced relay configuration options include setting setpoints, defining window parameters, introducing delays, indicating sensor errors, and monitoring power.
  • Configuration settings can be easily copied from one device to others of the same type via PR 45xx.
  • Active input signals support Reduced Uo Ex data < 8.3 V.
  • Temperature inputs offer internal or external Cold Junction Compensation (CJC) for enhanced accuracy.
  • Both active and passive mA outputs are available via the same two terminals.

Application:

  • PR Electronics 9116B can be installed in safe areas and Zone 2/Cl. 1 Div. 2 areas, receiving signals from Zone 0, 1, 2, as well as Zone 20, 21, 22, including M1/Class I/II/III, Div. 1, Gr. A-G.
  • Capable of converting and scaling temperature, voltage, potentiometer, and linear resistance signals.
  • Acts as a power supply and signal isolator for 2-wire transmitters.
  • Monitors error events and cable breakage via individual status relays or a collective electronic signal through the power rail.
  • Designed, developed, and certified for use in SIL 2 applications according to IEC 61508 standards.
  • Suitable for systems up to Performance Level “d” as per ISO-13849.

Technical Characteristics:

  • Operation and malfunction statuses are indicated by 1 green and 1 red front LED, while relay status is indicated by 1 yellow LED.
  • Provides 2.6 kVAC galvanic isolation between input, output, and supply.

Mounting:

  • Can be mounted vertically or horizontally without requiring distance between neighboring units.
