Temperature / mA converter

9113A

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.
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.
