RKC Instrument Co., Ltd. H-T1O-D-WD16-V8NN PLC Module

The RKC Instrument H-T1O-D-WD16-V8NN PLC module is a compact I/O unit designed to sit within RKC’s SR Mini HG SYSTEM, identified by the part number HT1ODWD16V8NN. It provides 0–12 VDC-compatible input signals, 4–20 mA analog outputs, and two DC output channels, enabling straightforward control and monitoring of sensors and actuators in small automation applications. The module supports a two-zone configuration, making it suitable for split-domain control within a single chassis. As part of RKC’s modular controller ecosystem, this unit is intended to be used alongside other SR Mini HG system modules to build compact, scalable control solutions without resorting to full-size PLC hardware. Typical use cases include process monitoring and general automation tasks where a small footprint, simple signal handling, and reliable I/O are required, such as laboratory equipment, packaging lines, and small manufacturing skids.
