The Series 9413 digital I/O coupler for Zone 1 is used to connect eight intrinsically safe contacts or NAMUR proximity switches and four intrinsically safe solenoid valves or indicator lamps to an FF H1. The 4-wire device has an external auxiliary power supply. The fieldbus can be operated in an intrinsically safe (FISCO) or non-intrinsically safe (high-power trunk) configuration. The input, output and fieldbus are galvanically separated.
- For connecting up to eight contacts or NAMUR proximity switches and up to four solenoid valves to a Foundation H1 Fieldbus in Zone 1
- Ex ia IIC inputs/outputs
- Operation on a high-power trunk or FISCO fieldbus
- Integrated functional blocks for DI, DO, DO_valve, MDI, MDO, AI (frequency), CI (counter) and LTB (logic)
