General

• Functional Description - The 9478 series digital output module valve for Zone 1 has eight channels for actuating pneumatic valves. The integrated 3/2-way solenoid valves are monitored to check for wire breakage and short-circuiting regardless of the drive status. An additional Ex i control input is suitable for safe shutdown up to SIL 2. Operation in combination with Ex i I/O modules is permissible.
• Highlights - Eight channels for pneumatic valves pneumatic outputs with integrated 3/2-way valves and SIL 2 shutdown input module in Zone 1 can be hot swapped
