SIL2 certified via Full Assessment according to IEC 61508
9107A is a 1- or 2-channel isolated 1:1 driver.
Operation and drive control of I/P converters, valves, and indicators.
Operation of HART devices is possible as the unit transmits HART communication signals bi-directionally.
9107A can be mounted in the safe area or in zone 2 / Class I, Division 2, Groups A, B, C, D.
The PR 45xx displays the process value for each channel and can be used to define high and low limits for the detection of loop current level. If these limits are exceeded, the status relay will activate.
Dual-channel versions can be used for signal splitter applications – 1 in and 2 out.
The PR 45xx detachable display and the green and red front LEDs indicate operation status for each channel.
A tag number can be defined for each channel.
Output line fault detection.
In the 1-channel version, the status relay can be used as a simple limit switch.
Suitable for the use in systems up to Performance Level “d” according to ISO-13849.
High galvanic isolation of 2.6 kVAC.
High accuracy better than 0.1%.
Continuous check of vital stored data for safety reasons.
The devices can be mounted vertically or horizontally without distance between neighboring units.
