Results
-
- Simplified power circuitry.
- Solenoid valve circuit buffer relays and terminal blocks are not required, with 8 consecutive block type solenoid valves used to simplify power circuitry and decrease board size.
-
- Simplified wiring within the board.
- Autonomous I/F boards are not required as the component count is less, drastically reducing board wiring.
-
- Reduced wiring construction costs.
- The DCS and solenoid valve storage panel are connected via a transmission cable bus, achieving large cost benefits in terms of on-site wiring work.
