The 9413 series digital I/O coupler for Zone 1 is used to connect eight intrinsically safe contacts or NAMUR proximity sensors and four intrinsically safe solenoid valves or indicator lamps to an FF H1. The four-conductor 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 sensors and up to four solenoid valves to a FOUNDATION Fieldbus H1 in Zone 1
- Ex ia IIC inputs/outputs
- Operated using High Power Trunk concept or FISCO Fieldbus
- Integrated function blocks for DI, DO, DO_valve, MDI, MDO, AI (frequency), CI (counter) and LTB (logic)
