Allen Bradley 1203-GK1 1203 Series Remote I/O Communication Module

Product Overview

The Allen Bradley 1203-GK1 serves as a high-speed communication gateway that bridges SCANport-based devices—primarily PowerFlex and 1336 PLUS drives—to an Allen Bradley Universal Remote I/O (RIO) network. This module enables a PLC-5, SLC 500, or ControlLogix processor to control, configure, and monitor drive parameters over long distances using standard RIO protocols. We supply this unit as 100% Brand New and Factory Original, ensuring immediate network compatibility and long-term signal integrity for your legacy automation infrastructure.

Technical Specifications

The 1203-GK1 hardware utilizes a dedicated 8-pin mini-DIN interface and high-speed differential signaling to manage data exchange:

Engineering Advantages

• Seamless Legacy Drive Integration: The 1203-GK1 allows modern control systems to access legacy drive data without replacing the motor control hardware. It translates complex drive parameters into standard I/O words, simplifying the integration of 1336 PLUS or PowerFlex 70 drives into existing RIO scanners.

• Flexible Addressing Logic: Onboard DIP switches allow engineers to set rack addresses and baud rates manually. This hardware-level configuration ensures the module retains its identity during power cycles and eliminates the need for specialized software during initial commissioning.

• Industrial-Grade Noise Immunity: The module features an isolated 3-pin Remote I/O port. This design rejects electromagnetic interference (EMI) common in drive cabinets, maintaining 230.4K baud communication stability even in proximity to high-frequency switching noise.

• Compact DIN-Rail Footprint: The slim IP30 housing snaps directly onto standard 35mm DIN rails. This small form factor permits installation in crowded control panels where space is at a premium, requiring only minimal clearance for the 8-pin mini-DIN cable.

• High-Speed Data Throughput: Support for 230.4K baud rates minimizes network latency. This ensures rapid response times for drive start/stop commands and real-time speed reference updates in high-performance motion applications.

FAQs

• Is this 1203-GK1 unit 100% Brand New?

  Yes. We guarantee this product is 100% Brand New and ships in its original Allen Bradley factory packaging. It has never seen service, ensuring the internal capacitors and connectors are in pristine condition.

• Does the 1203-GK1 require an external power supply?

  Yes. The module requires a dedicated 24V DC power source. While it connects to the SCANport, it does not draw its primary operating power from the drive; it manages its own 0.4 A maximum input current to ensure network isolation.

• Can I use this module to connect a drive to an EtherNet/IP network?

  No. The 1203-GK1 specifically targets Universal Remote I/O (blue hose) networks. If you require EtherNet/IP connectivity for a SCANport drive, you would typically need a 1203-EN1 or a similar bridge.

• What cable do I need for the device connection?

  The module uses an 8-pin mini-DIN SCANport cable. Always ensure the cable length stays within the maximum recommended distance for SCANport devices to prevent signal degradation.
