Honeywell 51304084-175 MC-TPIX12 Connection Board

Core Technical Specifications

The 51304084-175 MC-TPIX12 connection board serves as a high-density interconnect interface between field wiring and control system modules. This board measures 140 millimeters in height, 120 millimeters in width, and 60 millimeters in depth, with a total weight of approximately 0.52 kilograms. It provides terminal blocks for forty-eight signal points organized into twelve groups of four channels. The board integrates a 50-pin ribbon cable header for direct connection to compatible processor or I/O modules.

Signal Distribution and Connectivity

The 51304084-175 MC-TPIX12 organizes forty-eight signal points into twelve distinct groups for simplified system integration. Each group of four terminals shares a common return bus for efficient field device wiring. The board accepts solid or stranded wires from 14 to 22 AWG for reliable connections. It maps all signal points directly to the 50-pin ribbon connector for seamless data transfer. This design eliminates the need for additional adapter boards or complex cabling.

Physical Layout and Installation

You can mount this connection board onto standard DIN rails using the integrated spring-clip mechanism. Its front face provides easy access to all screw terminals for field wiring connections. The unit’s 60-millimeter depth fits comfortably into shallow control cabinets. LED indicators display power presence and group activity for quick visual verification. The board’s robust construction meets IP20 protection requirements for indoor industrial environments.

Signal Protection and Conditioning

This connection board includes integrated RC snubber circuits on each signal path for transient suppression. It also provides series current-limiting resistors to protect against accidental short circuits. The 51304084-175 MC-TPIX12 incorporates reverse-polarity protection diodes on the power input. These protective components safeguard the connected control system from field wiring faults. The board’s design ensures reliable operation in electrically noisy industrial environments.

Compatibility and System Integration

You can connect this board directly to Honeywell Series C I/O modules through the 50-pin ribbon interface. It also supports connection to third-party controllers using standard ribbon cable assemblies. The 51304084-175 MC-TPIX12 accommodates both digital and analog signals within the voltage rating. Its group organization matches common I/O module channel arrangements for plug-and-play compatibility. This board simplifies system upgrades by providing a standardized wiring interface.

Environmental Performance and Compliance

This connection board operates reliably across a temperature range of 0 to 60 degrees Celsius. It withstands humidity levels from 5% to 95% without any condensation. The 51304084-175 MC-TPIX12 meets IP20 protection standards for indoor installations. Its flame-retardant housing complies with UL 94 V-0 safety requirements. The board also carries CE and UL 508 certification for global industrial deployment.
