The ABB NTMP01, also cataloged as the NTMP01 Multi-Function Processor Termination Unit, provides serial communication termination for BRC, MFP, IET, ICT, and NKTU configurations, with support for RS-232-C and RS-485 interfaces and one control station serial link.

Hardware Specifications

Serial Communication and Termination

The NTMP01 provides physical termination for processor-related serial communication. Its interface configuration can use either two RS-232-C serial ports or one RS-232-C port combined with one RS-485 port. A separate control station serial link is also provided.

The termination unit is specified for use with BRC, MFP, IET, ICT, and NKTU equipment where required. Communication wiring should maintain the interface type and conductor arrangement specified by the associated control-system hardware.

For cabinet installation, the supplied cable insulation characteristics define the stated temperature and voltage ratings. PVC cable is specified as UL CL2 at 80 deg C and 300 V, while non-PVC PLTC cable is specified at 90 deg C and 300 V.

Frequently Asked Questions (FAQ)

Q: What serial interfaces does the NTMP01 provide?
A: The unit supports either two RS-232-C serial ports or one RS-232-C port and one RS-485 port, together with one control station serial link.

Q: Does the NTMP01 require cabinet cooling?
A: No additional cooling is required when the unit is installed in Bailey cabinets and operated within the specified environmental limits.

Q: What environmental operating range is specified?
A: The specified operating temperature is 0 to 70 deg C, with relative humidity from 5% to 90% up to 70 deg C, noncondensing.

Field Installation Guidelines

• Install the NTMP01 in the associated Bailey cabinet or approved mounting arrangement for the control-system configuration.
• Select RS-232-C or RS-485 wiring according to the connected processor and communication topology.
• Keep serial communication cables separated from high-current power conductors and other strong electromagnetic noise sources.
• Maintain appropriate cable shielding and cabinet grounding practices for the selected serial interface.
• Keep cabinet doors closed during operation. The supplied installation information specifies avoiding communication equipment within 2 m of the cabinet.
• Use cable insulation with ratings appropriate to the installation: PVC UL CL2 at 80 deg C and 300 V, or non-PVC PLTC at 90 deg C and 300 V.
• Verify terminal assignments and communication polarity against the applicable system wiring documentation before energizing the circuit.
