Overview
Enhance your ABB Symphony Plus system with the RDIO-01-KIT Digital I/O Extension Module from ABB Low Voltage Drives. This versatile module expands your control capabilities by providing three digital inputs and two relay outputs, crucial for integrating field devices and actuators into your automation processes. The digital inputs are designed to accept a wide voltage range, accommodating either 24…250 VDC or 110…230 VAC, offering flexibility for diverse installation requirements. Each input channel is optically isolated, ensuring signal integrity and protection against electrical noise. The module features two relay outputs, each capable of switching up to 1250 VA at 250 VAC or 5 A at 24 VDC, suitable for controlling higher power loads or interposing relays. Electrical isolation is a key feature, with 2.5 kV between digital inputs, digital outputs, and the power supply, and 1.5 kV specifically between DI2 and DI3, safeguarding your control system components. The RDIO-01-KIT utilizes 30 mA of the available 250 mA power supply, demonstrating efficient power management. This module is designed to seamlessly integrate with compatible ABB bases such as HBS01-FPH, HBS01-FPN, HBS01-EPD, VBS01-FPH, and VBS01-EPD, enabling straightforward expansion of your existing Symphony Plus architecture. For detailed technical specifications and compatibility, consult the ABB Symphony Plus hardware selector. SKU: RDIO-01-KIT. Manufacturer: ABB - Low Voltage Drives. UNSPSC Code: 39122004.
