Allen Bradley 1732E-8CFGM8R Digital I/O Modules

The Allen-Bradley 1732E-8CFGM8R, also cataloged as the 1732E-8CFGM8R ArmorBlock 8-Point Configurable Digital I/O Dual-Port EtherNet/IP Module, operates as a dedicated hardware component for direct physical/electrical execution within EtherNet/IP networks. The module executes high-density digital signal processing via 8 self-configuring sink inputs and sourcing outputs in an IP65/66/67/69K on-machine enclosure.

Hardware Specifications

Industrial Control & Backplane Communication Properties

As an integrated distributed I/O execution unit within Allen-Bradley automation architectures, the 1732E-8CFGM8R incorporates dedicated network routing and signal timing mechanisms:

• Profinet / EtherNet/IP Deterministic Networks: Features an integrated two-port Ethernet switch supporting Device Level Ring (DLR), star, tree, and linear network topologies to transmit CIP protocol data packets over TCP/IP and UDP/IP interfaces.
• Backplane Bus Communication Velocity: High-speed Ethernet physical layer transceivers support 10/100 Mbps full-duplex communication with configurable input digital filter delays selectable at 0, 2, 4, 8, or 16 ms intervals.
• I/O Density Scaling: Integrates 8 configurable input/output points into an on-machine housing without requiring external protective enclosures, featuring daisy-chain auxiliary power distribution to reduce field cable runs.

Frequently Asked Questions

Q: What network topologies are natively supported by the dual-port EtherNet/IP interface on the 1732E-8CFGM8R?

A: The integrated two-port switch supports Device Level Ring (DLR), star, linear, and tree topologies running at 10/100 Mbps full/half-duplex up to 100 meters per segment.

Q: Are the I/O channels on the 1732E-8CFGM8R protected by internal fuses?

A: No, the module does not contain internal fuses; each channel utilizes self-configuring circuitry supporting sink input or sourcing output operation.

Field Installation Guidelines

Proper mechanical mounting and grounding procedures ensure structural integrity and signal immunity in severe industrial environments:

• Mechanical Mounting and Environmental Sealing: Mount the module directly to the machine frame using designated mounting hardware. Ensure all M8 connector caps and mating field cables are torqued to maintain the IP65/66/67/69K ingress protection rating.
• Power Distribution and Daisy-Chaining: Connect 24 VDC auxiliary power using standard industrial wiring. When daisy-chaining auxiliary power across multiple blocks, ensure the continuous current draw does not exceed the maximum auxiliary loop rating of 4 A @ 24 VDC.
• Ethernet Cabling and Shielding: Route industrial-grade shielded Ethernet cables away from high-voltage AC motor drives and inductive loads. Connect the cable shield to functional earth to prevent electromagnetic noise from causing packet loss on CIP networks.
