No common negative wiring back to the module (characteristic of 1-wire design)
Suitable loads: Indicator lamps, 小さい 24 VDC solenoid valves, intermediate relay coils
- 典型的なアプリケーションシナリオ
包装機械, plastic injection & extrusion machinery, material handling conveyor lines, 繊維機械, auxiliary switching outputs for machine tools; ideal for centralized control of large quantities of 24 VDC solenoid valves and signal lamps.
- 選定メモ & Common Pitfalls
- If Sink (NPN) output is required → Select X20DO9321 instead of X20DO9322
- For humid, oily or condensation-prone environments → Order X20cDO9322 (conformal coated version)
- If channel current exceeds 0.5 A → Upgrade to X20DO8332 (8-チャネル, 2 チャンネルごとに)
- Do not drive high-power contactors directly; install intermediate relays as adapters
- Fault Diagnosis Guidelines
Channel LED off: No output command / module power loss
Channel LED on but load inactive: Missing external 24 VDC supply or open circuit
Recurring channel fault alarms: Load short-circuit, or missing freewheeling diode for inductive loads

X20BM11/BM15 base units, X20TB12 terminals and Automation Studio hardware configuration are fully compatible; no drawing or wiring changes required.
- Replacing X20DO9322 with X20DO9321
ハードウェア: Reverse all load positive/negative wiring
ソフトウェア: Change module model in Automation Studio hardware configuration; control logic remains unchanged
- 3-wire DO modules (DO9332 / DO8332 etc.) must NOT directly replace 1-wire X20DO9322
Different terminal assignment and power circuit architecture. Powering up mismatched hardware may cause load failure or component damage.
Supplementary Selection Advice
For new projects with large quantities of solenoid valves: Prioritize X20DO9322; 1-wire topology reduces cabling.
Frequent short-circuit faults or high individual valve current: Upgrade directly to X20DO8332.
Equipment for export to Europe & America: PNP series preferred. Confirm control circuit polarity before ordering for domestic non-standard machinery.
