Product Overview

The Allen-Bradley 1747-KE acts as a specialized, slot-mounted communications interface module engineered for the SLC 500 controller platform. This module establishes a dedicated processing bridge between DH-485 networks and RS-232C serial links. It allows an SLC 500 processor to transfer data packets across differing hardware lines, facilitating data exchange with computers, modems, third-party operators, and legacy serial peripherals.

The module features an onboard 3-port configuration layout that splits network management, peripheral data translation, and system configuration setups across independent channels. By handling low-level serial communication framing internally, the 1747-KE frees up the host SLC CPU from heavy communication tasks, preventing latency in time-critical machine logic execution.

We deliver this hardware exclusively as 100% brand new, original, and factory-sealed in its original factory packaging to guarantee total protocol compliance, unaltered internal circuitry, and absolute network reliability.

Engineering Advantages

Bidirectional Protocol Translation: The onboard processing engine seamlessly maps token-passing DH-485 data packets directly into point-to-point DF1 serial streams. This enables legacy Allen-Bradley architectures to integrate with modern SCADA packages, remote telemetry units (RTUs), and wireless radio modems.
Isolated Configuration Topology: The independent, dedicated configuration port lets plant technicians change baud rates, node addresses, and parity settings in real-time. This separate access channel ensures that network tuning tasks never interrupt the active DF1 process data stream on the adjacent runtime port.
Heavy-Duty Industrial Noise Rejection: Built to satisfy strict NEMA ICS 2-230 specifications, the hardware blocks high-frequency electrical spikes and electromagnetic background noise. This shielding stops data packet corruption in areas with high motor starter activity or adjacent welding equipment.
Direct Backplane Power Integration: The module draws its operating voltages directly from the SLC 500 backplane bus, consuming minimal current (0.04 to 0.15 Amps). This configuration removes the need for separate external power supplies and point-to-point DC wiring chains inside the control enclosure.

FAQs

Do you sell the 1747-KE communication module as a brand new component?
Yes. We supply the 1747-KE communication module strictly in 100% brand new, authentic, original factory condition. It ships within its original unopened factory-sealed box to guarantee performance and factory-calibrated internal processing.
Does the 1747-KE module require a dedicated slot next to the SLC CPU?
No. The 1747-KE integrates smoothly into any available local expansion slot inside a standard 1746 module mounting chassis. It communicates with the central processor across the standard parallel backplane bus without specific slot placement restrictions.
Can I use this module to connect an SLC 500 processor to a remote dial-up modem?
Yes. The DF1 interface port supports full RS-232C control handshaking lines (RTS, CTS, DTR, DCD). This allows the 1747-KE to control landline telephone modems, industrial cellular routers, and radio links using standard DF1 half-duplex slave configurations.
What specific software tool do I use to configure the internal port settings?
You configure the 1747-KE using standard Rockwell Automation configuration utilities (such as terminal software or integrated RSLogix setup tools) connected directly through the dedicated configuration port. Once you download the parameters, they store permanently in the module's non-volatile memory.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
