Honeywell 51155128-200 Embedded Computing Module

Configured for industrial computing, data processing, and network communication in Honeywell DCS architectures, the Honeywell 51155128-200 (51155128 Embedded Computing Module) provides local processing, storage, expansion, and Ethernet connectivity within the control system hardware layer.

Hardware Specifications

Honeywell DCS Computing and Network Architecture

The 51155128-200 provides computing resources rather than conventional discrete I/O channels. Its Intel Atom processor handles local computational tasks, while DDR memory and solid-state storage provide capacity for runtime software and data handling functions.

Dual Gigabit Ethernet interfaces can be assigned to redundant or logically separated network paths according to the DCS architecture. PCIe expansion provides an electrical interface for compatible communication or functional expansion hardware.

The HDMI and USB 3.0 interfaces provide local diagnostic, service, and peripheral connectivity. The 24 VDC supply input is regulated internally for the module electronics.

Frequently Asked Questions

Q: Is the Honeywell 51155128-200 a conventional I/O module?
A: No. It is an embedded computing module providing processor, memory, storage, network, video, USB, and PCIe expansion resources rather than discrete I/O channels.

Q: What network interfaces are provided?
A: The module provides two Gigabit Ethernet interfaces. Their use for network redundancy or logical network separation depends on the system configuration.

Q: What power input does the module use?
A: The specified supply input is 24 VDC, with typical current consumption of approximately 100 mA.

Field Installation Guidelines

Install the module in a compatible Honeywell system rack or panel location with sufficient clearance for connector access and service operations.

Verify the 24 VDC supply polarity and voltage before energizing the module. The power wiring should be routed separately from high-voltage switching conductors where practical.

For Ethernet connections, maintain physical separation from high-current motor, contactor, and power switching cables. Use appropriate shielded industrial Ethernet cabling where required by the control-system network design.

Connect protective and signal cable shields according to the cabinet grounding scheme. Avoid creating unintended ground loops through multiple shield termination points unless the system installation standard specifically requires them.

Before commissioning, verify Ethernet port assignment, PCIe expansion hardware, connected USB peripherals, and local HDMI service connections against the approved system configuration.
