PR Electronics – 9116B Universal Converter

An I.S. interface, also commonly referred to as intrinsically safe galvanic isolators or intrinsically safe barriers; are devices used to interface hazardous area process signals with safe area control equipment. Our selection of I.S. interfaces are designed to comply with global standards and directives including ATEX, IECEx, FM and UL.

Description

Advanced features

  • Configuration and monitoring by way of detachable display front (PR 4500); 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 others of the same type via PR 4500.
  • Reduced Uo Ex data < 8.3 V for active input signals.
  • TC inputs with internal CJC or external CJC for higher accuracy.
  • Active / passive mA output via the same two terminals.

Application

  • 9116B can be mounted in the safe area 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 scaling 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.
  • Suitable for the use in systems up to Performance Level “d” according to ISO-13849.

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.

Mounting

  • The devices can be mounted vertically or horizontally without distance between neighbouring units.
