YOKOGAWA MRI-214*B Relay Input Board

Description

The YOKOGAWA MRI-214*B Relay Input Board is a specialized industrial automation component designed for relay signal input integration, though direct technical specifications for this exact model are not available. Based on comparable YOKOGAWA input modules, key expected features and parameters include multi-channel input support, similar to other YOKOGAWA relay input modules that offer up to 32 channels with screw connections and integrated fuses. Expected electrical specifications may include input voltage ranges such as 0-150V AC, 0-250V AC, 0-300V AC, or 0-600V AC, with input impedance of 1M ohms and input frequency compatibility of 45Hz to 65Hz. It likely features robust isolation performance, with isolation test voltage of 2kV AC for 60 seconds between inputs, power supply, and casing, ensuring reliable operation in high-noise industrial environments. The board may support overload protection, with voltage inputs rated for 1.2x continuous load or 700V for 10 seconds, and current inputs rated for 1.2x continuous load or 1.5x load for 10 seconds. It is designed for integration with YOKOGAWA control systems, offering fast input response times (potentially under 8 milliseconds) and functions like on/off state detection and edge counting for button inputs, suitable for industrial monitoring, process control, and automated machinery applications.
