It enables precise discrete control of external industrial devices, bridging low-voltage logic with higher-power loads while maintaining isolation and protection in demanding operational environments.

Key Features

• 16 independently controlled relay outputs with positive logic

• Optical isolation for each channel to prevent interference and ensure safety

• Supports DC loads at 12 V and 24 V

• Integrated short-circuit detection and fault monitoring

• Compact footprint for easy rack installation

• Designed for critical turbine and process control applications

Technical Specifications

Applications

The module is designed to control a variety of field devices, including solenoids, motors, alarms, and contactors, within Mark VI turbine control systems. Its optical isolation ensures that control circuits remain protected from high-power load disturbances.

FAQ

Q: Can the module operate with AC loads?
A: The IS200DRLYH1BBB is designed specifically for 12 VDC and 24 VDC loads. AC operation is not recommended.

Q: How does it compare to IS200DRLYH1BBC?
A: The IS200DRLYH1BBB offers optical isolation on all 16 channels and independent relay control, whereas IS200DRLYH1BBC may have fewer isolated outputs or different load capacity.

Q: What happens if a short circuit occurs?
A: The module includes integrated short-circuit detection that triggers a fault status, allowing for safe shutdown and quick diagnostics.
