Honeywell 51197155-300 TDC 3000 Communication Interface Component

Configured for controller-to-I/O and controller-to-device serial communication in Honeywell TDC 3000 and Experion PKS Series C platforms, the Honeywell 51197155-300 (51197155 communication component) provides direct electrical interconnection for RS-485 communication paths. The documented configuration supports 24 VDC control power, Modbus RTU communication, and shielded signal transmission.

Hardware Specifications

RS-485 Communication and Signal Integrity

The 51197155-300 is specified for serial communication between Honeywell controllers, I/O subsystems, and peripheral devices. The module configuration uses an RS-485 physical interface with Modbus RTU protocol and supports up to 128 addressable devices per segment.

For the cable configuration, the shielded construction provides a controlled interconnection between the associated control hardware. Cable shielding and grounding should follow the cabinet and system wiring documentation to limit common-mode noise and electromagnetic interference.

Frequently Asked Questions

Q: What communication interface is specified for the module configuration?
A: The supplied data specifies an RS-485 serial interface using Modbus RTU.

Q: What supply voltage and current are specified for the module configuration?
A: The module configuration is specified for 24 VDC supply voltage with a typical current draw of 100 mA.

Q: Does the 51197155-300 have a fixed physical form?
A: The supplied documentation describes both a compact communication interface module and a factory-terminated shielded PLC communication cable configuration. The required form should be verified against the specific cabinet or node documentation.

Field Installation Guidelines

Install the component according to the applicable Honeywell cabinet and system wiring documentation. Verify the required module or cable configuration before connection.

For RS-485 wiring, maintain the specified signal-pair arrangement and avoid routing communication conductors in parallel with high-current switching or motor power conductors where practical. Keep cable shielding continuous through the intended communication path and terminate the shield according to the system grounding scheme.

For the cable configuration, verify DB9 connector pin assignment before energizing the connected equipment. Do not substitute pin assignments based solely on connector appearance.

For module installation, confirm the mounting position, connector orientation, supply wiring, and communication terminals against the applicable TDC 3000 or Experion PKS Series C documentation. Apply power only after signal and grounding connections have been checked.
