Conversor de Temperatura / mA
Principais características

Input for RTD, TC and mA
Active / passive mA output
1 or 2 channels
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 and signal simulation.
Copying of the configuration from one device to others of the same type via the display front.
TC inputs can use either the internal CJC or a terminal with a built-in Pt100 sensor (PR 5910, channel 1 / PR 5913, channel 2) for higher accuracy.
The device automatically detects whether it must supply an active or a passive current signal.
Advanced monitoring of internal communication and stored data.
SIL 2 functionality is optional and must be activated in a menu point.

The device can be mounted in and receive signals from non-classified area and zone 2.
Conversion and scaling of temperature (Pt, Ni and TC) and active current signals.
9113A 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.
