NTAI06 | ABB Bailey Analog Input Termination Unit

Termination units terminate and connect plant equipment to the INFI 90® strategic process management system. The NTAI06 Analog Input Termination Unit terminates field wiring for the IMASI03 Universal Analog Input Slave Module. This manual explains how to install and use the NTAI06 on the INFI 90 system. It has sections that describe the setup and cabling. Appendix A contains quick reference information about the IMASI03 module.The NTAI06 is a single printed circuit board that mounts in a NFTP01 Field Termination Panel. The termination unit (TU) has two connectors P1 and P2. A single Y-shaped cable connects to P1 and P2 on the termination unit. The other end of the cable connects to the slave module. The terminal blocks for field wiring are on the TU. Jumpers on the NTAI06 are set to match the type of input signal. Figure 1-1 shows an application example for the NTAI06.
The NTAI06 handles up to 16 analog inputs. Each voltage input may be differential or single ended. The IMASI03 can input these analog signal ranges:
• 1 to 5 VDC.
• 0 to 5 VDC.
• 0 to 10 VDC.
• -10 to +10 VDC, or user specified range within ± 10 VDC.
• System powered 4 to 20 mA DC.
• Externally powered 4 to 20 mA DC.
• Three-wire RTD.
• -100 to 100 mV.
• Thermocouple inputs.
