Silent Switching with Solid-State Reliability

This board provides 32 solid-state relay outputs for silent, wear-free switching operations. It handles frequent on-off cycles without the mechanical limitations of traditional relays. Many facilities choose this module for applications requiring high-speed output response. The unit eliminates contact bounce and arcing for cleaner signal switching.

Technical Specifications

Solid-State Output Design and Channel Layout

This module uses MOSFET-based switching elements for all 32 output channels. Each channel operates as a form-A normally open contact without moving parts. The solid-state design suits DC load switching exclusively from 5 V to 250 V DC. This technology provides superior longevity compared to electromechanical relays.

Power Consumption and Thermal Performance

The unit draws approximately 8 W under full output load conditions. Power dissipation remains low due to minimal on-state resistance of 0.1 Ω. The board requires less cooling compared to conventional relay assemblies. Heat sinks on the PCB dissipate thermal energy efficiently during normal operation.

Mechanical Construction and Physical Specifications

This board measures 250 mm wide and weighs 1.10 kg. The reduced weight reflects the absence of bulky electromagnetic coils. Four ribbon cable connectors interface with standard Yokogawa termination panels. The module mounts securely on backplanes using the standard guide rail system.

Switching Speed and Frequency Capability

These solid-state outputs achieve switching times under 1 millisecond. Turn-off occurs even faster at 0.5 milliseconds for precise control. The module supports continuous switching frequencies up to 1 kHz. This high-speed performance suits PWM applications and fast-cycling processes.

Diagnostic Feedback and Status Monitoring

Thirty-two LEDs indicate the instantaneous state of each output channel. An illuminated LED confirms the output is actively conducting current. This visual feedback helps operators verify output states during commissioning. Maintenance teams can quickly identify faulty channels for replacement.

Inrush Handling and Leakage Characteristics

Each output withstands peak surge currents of 6 A for 10 milliseconds. This capability handles capacitive loads and lamp inrush effectively. Off-state leakage current remains below 10 µA for sensitive loads. This low leakage prevents unintended operation of connected devices.

Certifications and Quality Assurance

The ARM55W maintains CE, UL, and CSA certifications for global acceptance. These approvals confirm compliance with safety and electromagnetic compatibility standards. Every board undergoes extensive electrical testing before leaving the factory. This rigorous process ensures dependable operation in control systems.
