ABB NTAI05 Analog Input Termination Unit

ABB NTAI05 Analog Input Termination Unit

Features

Multi-channel input: usually has 15 analogue input channels, can receive multiple on-site analogue signals at the same time, to meet the needs of industrial control systems for multiple sensor signal acquisition, reducing the number of terminal units required in the system.

Strong signal adaptability: it can accept various types of analogue input signals, such as 0-10V, ±10V voltage signals and 4-20mA current signals, etc., which can be adapted to different types of sensors, including temperature sensors, pressure sensors, flow sensors, etc.

Good isolation performance: the use of photoelectric isolation and other technologies to achieve electrical isolation between the input signal and the internal circuit and the control system, effectively preventing electrical interference in the field into the control system, improving the stability and reliability of the system, reducing the signal transmission errors and failures.

Convenient installation: compact structural design, relatively small size, occupies less space when installed in the control cabinet, and usually adopts standard installation methods and interfaces, such as rail mounting or screw fixing, etc., which is convenient for connection and wiring with other equipment, and the installation process is simple and fast.

Technical Parameters

Number of input channels: 15.

Input signal range: Voltage signal is 0-10V, ±10V, etc., and current signal is 4-20mA, etc.

Power supply voltage: usually 24V DC, relatively small working current, low power consumption.

Precision: high signal processing accuracy, can meet the precision requirements of analogue signal measurement and control in industrial processes.
