The Sanyo STNM-DR-160B(U) is a high-density digital mixed input/output module from Sanyo Denki's industrial automation product line, designed for small to medium-sized automation systems including factory equipment monitoring, building automation, and traffic signal control.
The module integrates 16 digital input channels and 16 digital output channels, supporting 24VDC dry/wet contact signal acquisition and relay/transistor output control. It features channel-level isolation, fast response, and self-diagnostics. The module is compatible with Modbus RTU/TCP and SANYO proprietary protocols, communicating with PLC/HMI systems via bus expansion.
This mixed I/O module features a compact design (120mm×100mm×35mm) supporting DIN rail installation, saving cabinet space. It operates on 24VDC independent power (18-30VDC range) with redundant power input (dual power terminals) to avoid single-point failures.
Module Type: Mixed I/O (16DI + 16DO)
Input Signal Types: Dry contact (passive) and wet contact (active)
Input Signal Range: 0-30VDC (wet contact)
Input Impedance: 4.7kΩ (wet contact)
Response Time:<1ms typical
Power Supply: 24VDC independent (18-30VDC)
Dimensions: 120mm × 100mm × 35mm

The STNM-DR-160B(U) is suitable for non-high-speed, high-channel density, cost-sensitive distributed I/O scenarios such as production line workstation status monitoring, intelligent building lighting control, and general factory automation. Its channel-level isolation ensures reliable signal acquisition in electrically noisy environments.
The module includes comprehensive self-diagnostic capabilities, allowing continuous monitoring of input/output status and communication integrity. The compact design and flexible mounting options make it ideal for retrofitting existing control cabinets and new automation system installations.
