Principais características

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

VISÃO GERAL

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.
The device automatically detects whether it must supply an active or a passive current signal.

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.

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