Advanced features

Configuration and monitoring by way of detachable display front (PR 45xx); 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 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
