Key Technical Specifications

Engineers select this termination panel for its robust construction and clear field wiring access. Its design simplifies installation while maintaining signal integrity for critical safety loops. Below, we detail the core technical parameters.

Detailed Features and Benefits

Centralized Field Wiring Termination
The Triconex 2551 7400056-110 consolidates all field device connections into a single organized location. It eliminates loose wiring and simplifies troubleshooting during maintenance activities. Consequently, you achieve cleaner cabinet layouts and faster fault identification.

Direct Compatibility with Triconex I/O Modules
You can use this panel with various Triconex analog input, analog output, and digital modules. It matches the channel count and signal types of the associated I/O modules perfectly. Therefore, you maintain signal integrity from field termination to safety logic solver.

Secure Screw Terminal Connections
The panel features high-quality screw terminals for reliable field wire retention. These terminals accommodate standard industrial wire gauges used in safety system installations. Thus, you ensure long-term connection stability in vibrating environments.

Simplified Integration via Cable Assemblies
A dedicated Triconex cable assembly connects the 7400056-110 panel to the I/O module. This cable maintains signal shielding and proper impedance for accurate data transmission. As a result, you reduce wiring errors and installation time significantly.

Robust Construction for Industrial Environments
The terminator panel withstands the temperature, humidity, and vibration found in control cabinets. Its materials resist corrosion and maintain electrical integrity over decades of service. Therefore, you depend on it for continuous operation in harsh plant conditions.

Clear Identification for Easy Maintenance
Each termination point includes clear markings matching I/O channel assignments. Technicians can quickly identify and trace field wires without reference to drawings. This feature accelerates both commissioning and future troubleshooting activities.

Applications for Field Termination

Analog Signal Termination
The 2551 7400056-110 terminates 4-20 mA and voltage signals from field transmitters. It provides a stable connection point before signals enter the safety system. You can rely on it for pressure, temperature, and flow monitoring applications.

Digital Input Field Wiring
This panel connects limit switches, pushbuttons, and relay contacts to digital input modules. Its organized layout simplifies wiring for large numbers of discrete field devices. Consequently, you maintain clarity in complex safety system installations.

Output Device Connections
For final control elements, the panel terminates wiring to solenoids and indicators. It ensures reliable connections for critical safety outputs. This application proves essential in emergency shutdown and fire and gas systems.
