The Allen-Bradley 1747-KE, also cataloged as the 1747-KE Interface Module, operates as a dedicated hardware component for serial communication conversion between DH-485 and DF1 networks within SLC 500 control systems.

Model Identification

The 1747-KE module provides three communication ports consisting of one DH-485 port, one DF1 port, and configuration interfaces. The module supports serial data exchange between SLC 500 processors and external devices requiring DF1 communication.

Hardware Specifications

EtherNet/IP and Serial Network Integration

The Allen-Bradley SLC 500 platform uses defined communication paths between processor units and interface modules. The 1747-KE provides serial communication handling through DH-485 and DF1 protocols, allowing connected devices to exchange controller data through configured communication channels.

The module operates as a protocol interface component rather than an independent controller. Configuration parameters define the communication behavior between the connected SLC 500 processor and external serial equipment.

Ordering Information

Installation Guidelines

Mounting and Wiring

• Install the module according to SLC 500 chassis installation requirements.
• Verify backplane connection alignment before inserting the module.
• Remove power from the chassis before module installation or removal.
• Separate communication wiring from high-voltage power conductors to reduce electrical interference.
• Use appropriate shield grounding practices for serial communication cables.

Communication Setup

• Configure DH-485 and DF1 parameters according to connected device requirements.
• Confirm baud rate, node addressing, and communication settings before operation.
• Verify cable termination and connector wiring before applying power.
• Avoid connecting incompatible communication protocols without proper configuration.

Frequently Asked Questions

• What communication protocols does the 1747-KE support?

The module supports DH-485 and DF1 serial communication interfaces for SLC 500 system communication and external device connections.

• How many communication ports are available on the 1747-KE?

The module provides three ports consisting of one DH-485 port, one DF1 port, and one configuration port.

• What power supply range is required for the 1747-KE?

The module operates with a 5 - 24 VDC power input range as specified for the interface module.

• Can the 1747-KE function as an SLC 500 processor?

No. The 1747-KE is a communication interface module and does not execute PLC control logic.

• Is the 1747-KE installed in an SLC 500 chassis slot?

Yes. The module is designed for integration within the SLC 500 hardware environment.

• Does the module require configuration before communication?

Yes. DH-485 and DF1 communication parameters must be configured according to the connected system requirements.

• Can the module directly convert all industrial protocols?

No. The module is designed specifically for supported DH-485 and DF1 communication functions.

• What should be checked before replacing an existing 1747-KE module?

Verify communication settings, wiring connections, power requirements, and compatibility with the existing SLC 500 configuration.
