The 9475/32-04 digital output modules for Zone 1 have four channels for controlling Ex i solenoid valves or indicator lamps. An additional Ex i control input is suitable for safe shutdown up to SIL 2. All outputs are short-circuit proof, galvanically separated from the system and individually monitored to check for wire breakage/short-circuiting.
- 4 channels for Ex i solenoid valves up to 40 mA
- Ex nA outputs with line fault monitoring, an LED fault and status display for each channel and SIL2 shutdown input
- Modules in Zone 1 can be replaced without having to disconnect the power supply (i.e. hot-swapped)
