9107A is a 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 detection of loop current level. If these limits are exceeded, the status relay will activate.
Features:
- 24 VDC supply via power rail or connectors
- Fast response time
- High active output load 725 Ohm / 20 mA
- Output line fault detection via status relay
- SIL2 certified via Full Assessment according to IEC 61508
