9475/32-04 series digital output modules for Zone 1 have four channels for actuating 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.
- Four channels for Ex i solenoid valves up to 40 mA
- Ex ia outputs with line fault monitoring and LED error and statusindication for each channel plus SIL 2 shutdown input
- Modules in Zone 1 can be hot swapped
