Product Overview

The ABB Bailey Infi 90 NTMP01 Multi-Function Processor Termination Unit serves as a high-reliability hardware interface within legacy Infi 90 distributed control systems. Engineered for critical industrial automation processes, power generation facilities, and continuous manufacturing applications, this board facilitates seamless data routing between multi-function processors and external peripheral equipment.

Integrating an onboard DC/DC converter, the NTMP01 ensures stable voltage regulation and isolation, mitigating signal noise and preventing ground loops. The termination unit provides vital serial communication capabilities, supporting dual RS-232-C channels or a hybrid RS-232-C and RS-485 network layout. This versatility allows engineering teams to maintain robust field-level communication, optimize process loop response times, and sustain operational uptime across complex control topologies.

Hardware Architecture & Communication Protocols

The NTMP01 architecture relies on a rugged printed circuit board design engineered to withstand the thermal and electrical stresses of continuous industrial environments. The onboard DC/DC converter accepts system-level power and transforms it into clean, regulated voltage to drive the serial communication transceivers, safeguarding data integrity during peak processing periods.

Flexibility defines the board's serial interface layout. Plant engineers can configure the hardware via onboard jumpers to utilize either two independent RS-232-C serial ports for point-to-point diagnostics, or one RS-232-C port alongside one RS-485 port. The RS-485 configuration unlocks multi-drop, long-distance industrial networking, enabling efficient Modbus or proprietary serial link deployments back to the centralized control room.

Physical and Electrical Parameters

Field Deployment & Grounding Practices

Successful deployment of the NTMP01 depends heavily on proper grounding and cabinet environmental controls. Install the termination unit inside a standard Bailey Infi 90 termination module slot, ensuring the card edge connectors align perfectly before seating the board.

To maintain serial communication integrity and prevent signal degradation over RS-485 networks, utilize high-quality shielded twisted-pair (STP) cabling. Connect the cable shield to the designated chassis ground point at the termination unit side only; floating the shield at the field device end prevents harmful ground loops. When running RS-485 lines to external devices, maintain a minimum bending radius of ten times the outer cable diameter to protect the internal conductor geometry.

Industrial Environmental Resilience

The NTMP01 demonstrates exceptional resilience when deployed in demanding industrial settings characterized by high electromagnetic interference (EMI) and shifting thermal loads. It interfaces directly with legacy Infi 90 multi-function processors, providing an immediate communication bridge without requiring complex software emulation or system-wide firmware overhauls.

This termination unit delivers continuous, low-latency serial data throughput under fluctuating conditions. The localized galvanic isolation provided by the DC/DC converter blocks high-voltage transients originating from field cabling, ensuring that localized electrical faults do not propagate to the primary control backplane or jeopardize broader plant operations.

To protect fragile micro-electronics from electrostatic discharge during transit, components are vacuum-sealed within anti-static industrial packaging and supported by rigid, impact-absorbing foam structures.

Technical Field Support

Q1: How do I switch the secondary port from RS-232-C to RS-485?

A1: Port configuration requires positioning the physical onboard hardware jumpers according to the ABB Bailey system documentation prior to inserting the card into the live chassis backplane.

Q2: What is the primary function of the integrated DC/DC converter on this board?

A2: The converter steps down and regulates backplane power to supply clean, isolated voltage directly to the communication ports, shielding the system against signal noise.

Q3: Is the NTMP01 compatible with older Network 90 installations as well as Infi 90?

A3: Yes, the NTMP01 architecture maintains backwards compatibility with specific legacy Network 90 systems, provided the processor module firmware supports the dual serial configuration.

Q4: How should terminal resistors be applied if utilizing the RS-485 port configuration?

A4: A 120-ohm terminating resistor must be installed across the data lines at the final physical device on the RS-485 network loop to prevent signal reflection.
