Honeywell Triconex 2401 – Dual Redundant Power Supply Module (Series 1)

In stock

Product Introduction:
The Triconex 2401 is a dual-redundant power supply module that provides clean, regulated DC power to all other modules in the Triconex rack. It takes raw 120V AC or 240V AC input from the plant power system and converts it into the precise 5V DC required by the processor and I/O modules. The “2401” designation identifies it as a power supply in the Series 1 family. The dual-redundant design means the module contains two completely independent power supplies (A and B) within a single card. If one supply fails, the other takes over instantly with zero interruption to the safety system. This module is absolutely essential; without it, no other module in the rack can operate.

Technical Specifications:
Module Type: Dual Redundant Power Supply
Series: Series 1
Input Voltage: 120V AC or 240V AC (selectable via jumper), 47 to 63 Hz
Output Voltage: 5V DC, 24V DC (auxiliary)
Output Current: 5V at 15 Amps (total for both supplies), 24V at 2 Amps
Redundancy: N+1 redundancy (two supplies, either can carry full load)
Efficiency: Greater than 80%
Ripple and Noise: Less than 50mV peak-to-peak on 5V output
Protection: Over-voltage, under-voltage, over-current, short-circuit, over-temperature
Fan Redundancy: Dual internal cooling fans with automatic failover
Diagnostics: Per-supply voltage and current monitoring, fan status, temperature monitoring
Form Factor: Standard Triconex Eurocard (approximately 6U height)
MTBF: Greater than 200,000 hours

Functional Features:
Dual Independent Supplies: Two completely separate power conversion circuits in one module. A failure in one does not affect the other.
Hot Swappable: In redundant configuration (2401A + 2401B), one module can be removed and replaced while the system is running.
Sequenced Startup: Controls the order in which voltages come up during startup, preventing inrush currents that could trip breakers.
Fan Failover: If one internal fan fails, the other automatically increases speed to compensate, preventing overheating.
Voltage Supervision: Continuously monitors output voltages and alarms if any voltage drifts outside acceptable limits.
Current Sharing: In dual-module configuration, both 2401 modules share the load equally, extending the life of both.
Browntout Protection: Holds up the 5V output for at least 20 milliseconds during a brief AC power dip, preventing unnecessary system resets.

Application Scenarios:
Primary Rack Power: Serves as the main power source for the Triconex safety controller in the control room.
Redundant Power Architecture: Deployed in pairs (A and B) so that if one module fails, the other seamlessly takes over the entire load.
UPS Backup: Provides clean power from the UPS battery bank during a plant blackout, ensuring the safety system remains operational for safe shutdown.
Remote Rack Power: Powers remote I/O racks located near hazardous areas, receiving AC power via long cable runs from the main control room.
