Allen-Bradley 1202-H90 SCANport HIM Extension Cable

The Allen-Bradley 1202-H90, also cataloged as the 1202-H90 SCANport HIM extension cable, operates as a dedicated hardware component for remote Human Interface Module signal transmission within PowerFlex 7 drive and SMC-Flex soft starter communication networks.

Suffix Breakdown & Model Matrix

The supplied documentation identifies 1202-H90 as a fixed-length 9 m SCANport HIM extension cable. No official Allen-Bradley suffix matrix or configurable ordering structure is specified in the provided technical material.

Hardware Specifications

Deterministic Communication Path Integrity

The 1202-H90 maintains SCANport communication continuity between the drive control section and remotely mounted HIM assemblies. Shielded conductor construction reduces susceptibility to radiated electromagnetic interference generated by adjacent motor output conductors, contactors, and variable frequency drive switching events.

Factory-terminated male-to-female SCANport connectors maintain communication path consistency without additional field termination procedures. The cable assembly supports deterministic keypad response and LCD data exchange between compatible Allen-Bradley motion control products and remotely positioned operator interfaces.

The fixed 9 m cable length establishes defined communication path impedance and minimizes signal degradation associated with unsupported extension splices or unshielded field modifications.

Frequently Asked Questions

Q: Can the 1202-H90 cable be extended beyond 9 m through additional couplers?
A: The supplied documentation specifies a fixed 9 m assembly. Additional extension segments or inline couplers may affect communication integrity and should be validated against the connected drive system requirements.

Q: Does the cable require separate grounding for EMI shielding effectiveness?
A: Shield continuity is normally maintained through the SCANport connector assembly. Proper enclosure grounding and cable routing practices should be followed to reduce radiated interference exposure.

Q: Is the cable compatible with non-SCANport Allen-Bradley interfaces?
A: The assembly is specified for SCANport-compatible HIM communication systems including PowerFlex 7 drives, SMC-Flex soft starters, and compatible HIM modules.

Field Installation Guidelines

Route the cable separately from motor output leads, brake resistor conductors, and high-current AC feeders. Maintain physical separation from variable frequency drive output wiring to reduce conducted and radiated electrical noise coupling.

Avoid excessive bending radius or continuous mechanical stress near connector transitions. Secure the cable at intermediate points where vibration or panel movement may transfer strain into the SCANport connectors.

When mounting the HIM remotely on enclosure doors or operator stations, verify that cable routing does not interfere with grounding straps, hinged panel movement, or ventilation assemblies.
