HYUNDAI DOM16 – 16-Point Transistor Digital Output Module | HD1000 Series PLC
Engineering Background
The HYUNDAI DOM16 is a high-density transistor digital output module engineered for the HD1000 Series Programmable Logic Controller platform. Designed to meet the demanding requirements of industrial automation environments, it delivers reliable, high-speed discrete output control for machinery, process lines, and motion systems.
Product Positioning
Targeted at OEM machine builders, system integrators, and MRO procurement engineers who require a proven, drop-in compatible output expansion card for existing HD1000 PLC installations. The DOM16 eliminates relay-based output bottlenecks and supports high-frequency switching applications where relay life and response time are critical constraints.

Engineering Advantages
- High-speed switching: Sub-millisecond response eliminates timing lag in high-frequency output cycles.
- Photocoupler isolation: Protects the PLC backplane from field-side voltage transients and ground loops.
- 16-point density: Maximizes I/O per slot, reducing panel footprint and wiring complexity.
- Short-circuit protection: Built-in hardware protection prevents module damage from field wiring faults.
- Direct HD1000 compatibility: No adapter or firmware update required — plug-and-play slot insertion.
System Architecture & Signal Flow
The DOM16 interfaces directly with the HD1000 PLC backplane via the proprietary I/O bus. The CPU writes output data to the module’s internal register on each scan cycle. The photocoupler stage isolates the logic-side signal before driving the transistor output stage. Each output channel drives an external load (solenoid, relay coil, indicator lamp, etc.) connected between the output terminal and the 24 VDC common. The module’s onboard protection circuit monitors each channel for overcurrent conditions and latches off the affected point to prevent thermal damage.

Technical FAQ
Q: Is the DOM16 compatible with HD1000S and HD1000H chassis variants?
A: Yes. The DOM16 is compatible with all HD1000 Series backplane variants. Verify slot type (standard I/O slot) before installation.
Q: Can the DOM16 drive inductive loads such as solenoid valves directly?
A: Yes, with a flyback diode installed across the inductive load to suppress voltage spikes. This is standard practice and does not affect module warranty.
Q: What is the maximum switching frequency?
A: The transistor output supports switching frequencies up to 1 kHz under rated load conditions.
Q: Is a replacement available if the module is discontinued?
A: Konmask.com maintains buffer stock of legacy HYUNDAI I/O modules. Contact us for long-term supply agreements.
Q: Do you provide a test report or incoming inspection certificate?
A: Yes. Inspection reports are available upon request for orders of 3 units or more.
