  • 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 45xx.
  • 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.


  • 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.


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