16137-188
Product Name
Primary: Yokogawa Variant
16137-188Yokogawa 32-Channel Digital Input Module (Industrial Automation)
Model Context: The “16137” series aligns with Yokogawa’s industrial I/O module portfolio, and “-188” specifies the 32-channel, 24V DC digital input configuration—distinct from analog modules or temperature controllers in the same product family .
Secondary: Siemens Variant
16137-188Siemens APACS+/Quad Log Redundant ACM/LIM Cable (2M Length)
Model Context: Labeled as a “module” in distributor terminology, it is actually a 2-meter redundant communication cable for Siemens APACS+ and Quad Log DCS systems, connecting ACM (Advanced Communication Module) and LIM (Local I/O Module) components .
2. Product Description
Yokogawa 16137-188 Digital Input Module
The 16137-188 is a high-reliability, industrial-grade digital input module engineered by Yokogawa for automation control systems in manufacturing, energy, and process industries . Its core function is to convert discrete digital signals (e.g., from proximity sensors, limit switches, or pushbuttons) into controller-compatible data, enabling real-time monitoring of device status (e.g., “valve open/closed,” “conveyor running/stopped”).
Designed for harsh industrial environments, the module integrates 32 independent input channels to support high-density signal acquisition—critical for complex systems requiring simultaneous monitoring of multiple field devices. It features built-in signal conditioning and protocol compatibility (RS-485/Modbus), ensuring seamless integration with Yokogawa DCS, PLCs, or third-party automation platforms.
Key technical values include:
- High-Density Connectivity: 32 channels eliminate the need for multiple single-channel modules, reducing cabinet space and wiring complexity.
- Broad Compatibility: Supports TTL/CMOS signal types and 0-24V DC input, working with most industrial digital sensors and actuators.
- Rugged Design: IP65 protection rating shields against dust and low-pressure water jets, while an operating temperature range of -20°C to +70°C suits extreme factory conditions .
- Flexible Communication: RS-485 and Modbus support enable long-distance data transmission (up to 1km for RS-485) and interoperability with legacy systems.
