Advanced features

• Configuration and monitoring by way of detachable display front (PR 4511/4501); 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 the display front.
• TC inputs with internal CJC or external CJC for higher accuracy.
• Active / passive mA output via the same two terminals.

Application

• The device can be mounted in and receive signals from non-classified area and zone 2.
• 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.
• 9116A 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.
