Conveyor & Discrete Control Solution — OMRON SRT2-VOD16ML-1 | SRT2 Series
Where This Product Is Used
The OMRON SRT2-VOD16ML-1 is a CompoBus/S slave terminal output module engineered for high-density discrete control in industrial environments. Engineers deploy this module wherever a large number of NPN transistor outputs must be distributed close to the load — eliminating long home-run wiring runs and reducing panel footprint.
- Conveyor & Material Handling: Drives solenoid valves, motor starters, and indicator lamps along conveyor lines via distributed I/O nodes.
- Packaging Machinery: Controls pneumatic actuators, reject gates, and label applicators in high-speed packaging lines.
- Assembly & Test Fixtures: Provides 16 individually addressable NPN outputs for fixture clamping, part presence signaling, and pass/fail indication.
- Automotive Body Shops: Interfaces with welding guns, transfer units, and safety light curtains in body-in-white lines.
- Food & Beverage Processing: Operates in wash-down-adjacent panels controlling filling valves, conveyor drives, and diverter gates.
- Intralogistics & Sortation: Manages diverter blades, pop-up wheels, and zone-control drives in warehouse sortation systems.

Why Engineers Specify This Model
- Terminal Block Convenience: The “-ML-1” suffix denotes a screw-terminal (ML) variant, eliminating proprietary connectors and simplifying field wiring and maintenance.
- High-Speed Network: CompoBus/S at 750 kbps delivers deterministic cycle times as low as 0.5 ms for 256 I/O points — critical for motion-synchronized discrete outputs.
- Distributed Architecture: Place the module at the machine, not in the panel. Reduces wiring cost, improves noise immunity, and shortens commissioning time.
- 16 Outputs in One Node: Maximizes I/O density per node address, keeping node counts low and network configuration simple.
- Proven OMRON SRT2 Ecosystem: Fully interoperable with CS/CJ/CP-series PLCs via SRM1 or CS1W-SRM21 master units — no gateway required.
- NPN (Sink) Output: Compatible with the majority of Asian-market solenoid valves and actuators wired to a common positive rail.
Complete System Bill of Materials

Application-Specific FAQ
Q: Is the SRT2-VOD16ML-1 compatible with CJ2 series PLCs?
A: Yes. Use a CS1W-SRM21 CompoBus/S master unit installed in the CJ2 backplane. The SRT2-VOD16ML-1 is recognized as a standard 16-output slave node.
Q: What is the difference between SRT2-VOD16ML-1 and SRT2-VOD16-1?
A: The “ML” designates a screw terminal block (ML connector) interface. The non-ML variant uses a dedicated OMRON connector. The ML version is preferred for field wiring flexibility.
Q: Can I mix input and output slave modules on the same CompoBus/S network?
A: Yes. CompoBus/S supports mixed input/output slaves on the same trunk. Each slave occupies one node address regardless of I/O type.
Q: What is the maximum cable length for CompoBus/S at 750 kbps?
A: 100 m trunk length at 750 kbps using flat cable; 500 m at 93.75 kbps using round cable. Drop lines are limited to 3 m per node.
Q: Do you provide SRT2-VOD16ML-1 with a warranty?
A: Yes. New-in-box units carry the standard OMRON warranty. Tested surplus units carry a 90-day Konmask functional warranty. Contact us for details.
