PR9113B, Temperature / mA converter

• * Input for resistance sensor (RTD), thermocouple (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

Advanced features

• * Configuration and monitoring by way of detachable display front (PR 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 5910Ex, channel 1 / PR 5913Ex, 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.

Application

• * The device can be mounted in the safe area and in zone 2 / cl. 1 div. 2 and receive signals form zone 0, 1, 2 and zone 20, 21, 22 including M1 / Class I/II/III, Div. 1, Gr. A-G.
• * Conversion and scaling of temperature (Pt, Ni and TC) and active current signals.
• * The 9113 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.
