The NTAI05 is a high-level 16-channel analog input termination unit for the ABB Bailey INFI 90 and Symphony DCS series.
Screw-Clamp Terminal Blocks
Onboard Dipshunt Configurability
NFTP01 Panel Mounting
NTAI05 acts as a passive interface connecting field devices including transmitters and sensors through 16 channels. It integrates with FEC slave modules via cabling, features screw-clamp terminals, and supports signal ranges configured with dipshunts. The hardware is for NFTP01 panels with standard dimensions, contains zero chemical batteries, and complies with WEEE and UL standards for industrial MRO applications.

Thermal Power Generation
Used in boiler feedwater systems to terminate and route 4-20mA analog signals from steam pressure transmitters and furnace temperature sensors to DCS modules.
Hydroelectric Power Generation
Connects continuous analog process data from hydro-turbine generator thrust bearing oil temperatures, upstream penstock pressures, and tailrace water level transmitters.
Petroleum Refining
Collects analog electrical signals from crude oil storage tank level gauges and transfer pipeline flowmeters in atmospheric/vacuum distillation and catalytic cracking units.
Iron & Steel Metallurgy
Used in blast furnace blowing and hot blast stove control systems to collect key process control parameters such as air volume, air pressure, and cooling water flow.
Pulp & Paper
Used in pulping and papermaking sections to route analog signals from pulp consistency meters, dryer steam pressure transmitters, and white water flowmeters into FEC processing modules.
Urban Rail Transit
Used in Environmental Monitoring Systems for underground pumping stations and ventilation plant rooms along subway lines to collect analog data on sump water levels, duct differential pressures, and ambient temperature/humidity.
Duplicate the original board's dipshunt positions during replacement to prevent signal errors. Tighten terminal screws regularly against vibration-induced 4-20mA signal spikes. Never connect 110V/220V AC high voltage to avoid destroying sampling resistors and downstream modules. Keep the enclosure dry, clean, and properly grounded to prevent conductive dust from shorting the common negative reference.
Technical notes
Technical notes
NTAI05 supports input signal range configuration for individual channels using onboard dipshunts, mounts onto NFTP01 panels, and delivers process data to FEC analog slave input modules via cabling.
Used to connect analog physical signals like 4-20mA from field instruments to DCS modules.
How many input channels are integrated inside NTAI05?
It is configured with a total of 16 independent analog input field signal channels.
How does NTAI05 transmit signals to the main processor module?
Connects to the input processing card via an NKAI01 cable through its 24-pin receptacle.
What is the onboard resistor value inside NTAI05?
It features built-in 250-Ohm high-precision current sampling resistors for each channel.
Can NTAI05 isolate individual channel signals?
No, its 16 input channels are non-isolated and share a common negative reference.
What technical detail requires the most attention when maintaining NTAI05?
Terminal screws must be checked and tightened regularly to prevent loose contacts from vibration.
