Comprehensive I/O Interface for Drive Control
The NIOC-01C inverter I/O board expands the standard control interface of ABB ACS800 and ACS850 drives. This inverter I/O board provides a rich set of analog and digital channels for flexible drive integration. Two differential analog inputs accept either ±10 V voltage or 0-20 mA current signals from external controllers or sensors.
Two analog outputs deliver 0-20 mA or 0-10 V signals for drive speed or torque reference, giving engineers precise control over motor performance. Six optically isolated digital inputs accept 24 VDC signals from push buttons, selector switches, or PLC outputs. Three configurable digital outputs serve as relay or transistor switches for indicating drive status or controlling external equipment.
Precision and Response Characteristics
The analog channels feature 12-bit resolution, which translates to 0.025% of full-scale accuracy for precise measurement and control. The conversion time for analog inputs reaches approximately 2 ms, enabling real-time response in dynamic applications. The digital inputs respond within 1 ms, making them suitable for high-speed interlocking and safety functions.
The NIOC-01C achieves all I/O processing through the drive’s RMIO processor, which ensures seamless integration without additional programming. This inverter I/O board stores its configuration in non-volatile memory on the drive, guaranteeing reliable recovery after power interruptions.
Physical Design and Installation
This inverter I/O board measures only 100 mm x 50 mm x 30 mm and weighs a mere 0.08 kg. Its compact form factor allows direct mounting onto the RMIO board inside the drive cabinet. A 24-pin flat ribbon cable provides the electrical connection to the main control board, simplifying installation and reducing wiring errors.
A single green LED indicates the presence of 5 VDC power from the drive backplane. This visual confirmation helps technicians quickly verify basic functionality during startup. The board requires no external power supply because it draws all necessary energy directly from the drive.
Environmental and Operational Limits
The NIOC-01C operates reliably across a temperature range of 0°C to +50°C. This inverter I/O board also withstands relative humidity from 5% to 95% (non-condensing) and resists vibration up to 1G at 10-100 Hz.
