ABB Bailey NTAI05 6632115T1 Analog Input Termination Unit

NTAI05 6632115T1 Analog Input Terminal Unit is an industrial module designed by ABB/BAILEY for INFI 90, Symphon,y and Harmony control systems. It is used to collect analog signals from on-site sensors and transmit them stably to the control system. It supports multiple channel inputs, flexible configuration of signal types (current or voltage), has a compact structureand, and is easy to install and maintain.

1. Multi-channel analog input processing
NTAI05 6632115T1 Analog Input Terminal Unit supports a large number of analog signal acquisition (up to 15–16 channels), which is suitable for the need to simultaneously obtain multiple signal data in complex systems.
2. Flexible configuration of signal types
The DIP switch allows for the configuration of various analog input types, including common current (4–20mA) and multiple voltage ranges, enabling the module to be compatible with a wide range of on-site sensors.
3. Compatible with the ABB INFI 90 control system
NTAI05 6632115T1 Analog Input Terminal Unit is used in conjunction with different slave modules (such as IMASM01, NASM01, IMASI02, etc.) of the ABB Bailey INFI 90 series control system to achieve data connectivity between the field and the control machine.
4. Reliable hardware design
The entire module is designed with industrial-grade components, meeting the requirements for long-term continuous operation and industrial site environments.
5. Single-board style, simple connection
A single PCB board integrates multiple channel inputs, featuring clear terminals and backplane connection ports, facilitating on-site installation, inspection, and maintenance.

Through the configuration of the DIP switch and the design of high-quality circuits, the input signals can be accurately sampled and transmitted, which helps the main control system to read the on-site data more precisely.

The multi-channel and flexible configuration feature makes this module highly suitable for the field of process automation, such as in the on-site data collection of industries like chemical engineering, power, and metallurgy.

NTAI05 6632115T1 Analog Input Terminal Unit is a standard component of the ABB Bailey INFI 90 system. It is fully compatible with multiple subordinate modules and flat buses, and the overall system design has a clear logic, facilitating engineering expansion and maintenance.
✅ Easy to maintain and on-site debugging
Clear terminal markings and fixed DIP settings facilitate on-site installation, inspection,n and fault diagnosis, and are easier for maintenance personnel to master.

Q1: How is the isolation and anti-interference capability of the module regarding the input signals?
A1: Each channel's input signal is internally isolated, which can reduce the impact of electrical noise and ground loop interference on the control system, ensuring the stability of data acquisition.

Q2: What are the environmental requirements for module installation?
A2: It is recommended to install in standard control racks or patch panels. The general environmental temperature requirement is 0–55℃, with relative humidity not exceeding 95% (no condensation), and it should be avoided to be near strong magnetic fields or high-frequency interference sources.

Q3: Does this module support hot plugging or online replacement?
A3: NTAI05 is of the termination module type. Generally, it does not support hot plugging. During maintenance or replacement, the corresponding system power needs to be turned off to avoid abnormal signals or system alarms.

Q4: How is the communication between the module and the control system achieved?
A4: NTAI05 transmits analog signals through the backplane bus to the corresponding input module of the main controller, without the need for additional communication cables, ensuring the rapid and synchronous transmission of signals.

Q5: What are the fault detection and diagnosis functions of the module?
A5: It can detect open circuits, short circuits, and input over-range situations. Some systems can obtain the fault status through the control software, enabling quick identification of the abnormal signal source.
