YOKOGAWA ANB10D-425/CU2T

Ultra-fast response capabilities:

Building on the ANB10D-425/CU2N’s performance, the ANB10D-425/CU2T achieves response times of ≤5ms for both on and off events—half the delay of its counterpart. This speed is critical in precision manufacturing, such as in robotics assembly where milliseconds determine the accuracy of component placement. In automotive welding lines, the module’s rapid detection of workpiece position changes ensures welding robots adjust their paths instantly, reducing defects in high-speed production.

Enhanced surge protection:

The ANB10D-425/CU2T incorporates advanced surge protection circuitry not found in the ANB10D-425/CU2N, enabling it to withstand voltage transients up to 2kV. This feature is invaluable in industrial environments with frequent power fluctuations, such as in mining operations where heavy equipment causes voltage spikes. The module’s ability to absorb electrical surges prevents damage to the control system during lightning strikes or equipment startups, reducing unplanned downtime.

Superior isolation rating:

With 1000V AC isolation—double the protection of the ANB10D-425/CU2N—the ANB10D-425/CU2T provides exceptional protection against electrical interference. This is particularly beneficial in high-voltage environments like steel mills or power generation facilities, where electromagnetic noise from large transformers and motors can disrupt signal integrity. The enhanced isolation ensures accurate signal detection even when installed near high-power equipment, maintaining control system reliability.

Extended environmental tolerance:

The ANB10D-425/CU2T operates in temperatures ranging from -20°C to 60°C, outperforming the ANB10D-425/CU2N’s -10°C to 55°C range. This makes it suitable for outdoor installations such as renewable energy plants, where temperature extremes are common. In desert solar farms or arctic oil pipelines, the module reliably monitors sensor inputs regardless of ambient conditions, ensuring continuous operation in critical infrastructure.

6. Installation, commissioning and maintenance instructions

Installation preparation

Before installing the ANB10D-425/CU2T, verify the control rack is powered off and compatible with YOKOGAWA systems. Ensure the mounting location meets the expanded temperature range (-20°C to 60°C) and is protected from direct exposure to water or chemicals. Prepare tools including a torque screwdriver (0.5-1.0 Nm) and wire strippers for 20-16 AWG cables.

Use twisted-pair shielded cables for all connections, with the shield grounded at both ends to maximize noise immunity. Confirm input signals fall within the 12-24V DC range and that total current across all channels does not exceed 40mA. For hazardous environments, ensure proper sealing of cable entries to maintain environmental protection. Label each channel clearly to match connected devices, facilitating troubleshooting.

Maintenance suggestions

Perform bi-annual visual inspections of the ANB10D-425/CU2T to check for corrosion, loose connections, or physical damage—more frequently in highly dusty or humid environments. Use compressed air to remove debris from ventilation openings. Monitor diagnostic data via the control system to track channel performance and identify potential issues before failure.

Calibrate input thresholds annually using a precision voltage source to maintain response accuracy. If a channel exhibits delayed response or false triggers, check for cable damage before replacing the module. When replacing the ANB10D-425/CU2T, transfer configuration settings using YOKOGAWA’s configuration software to ensure operational consistency. Store spare modules in anti-static packaging within the specified storage temperature range (-30°C to 80°C).
