Temperature / mA converter

Temperature / mA converter
Temperature / mA converter
9113A
– Input for RTD, TC and mA
– Active / passive mA output via the same two terminals
– 1 or 2 channels
– 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 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.
Applications
Application
• The device can be mounted in and receive signals from nonclassified 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.
Technical characteristics
• 1 green and 2 red front LEDs indicate operation status and
malfunction.
• 2.6 kVAC galvanic isolation between input, output and supply.
Mounting
• The devices can be mounted vertically or horizontally without
distance between neighbouring units.
