Universal converter
9116B
– Input for RTD, TC, Ohm, potentiometer, mA and V
– Supply for 2-wire transmitters
– Active / passive mA output and relay output
– Can be supplied separately or installed on power rail, PR type 9400
– SIL 2-certified via Full Assessment
Advanced features
• Configuration and monitoring by way of detachable display
front (PR 4501); 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 PR4501.
• Reduced Uo Ex data < 8.3 V for active input signals.
• TC inputs with internal CJC or external CJC for higher
accuracy.
• The device automatically detects whether it must supply an
active or a passive current signal.
Connections
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.
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.
