2866514, Phoenix Contact Redundancy module, TRIO-DIODE/12-24DC/2X10/1X20 Series

Phoenix Contact TRIO DIODE Redundancy Module

The din rail mounting, Trio Diode redundancy modules from Phoenix contact are designed to isolate parallel-switched PSU’s. Using the redundancy module prevents short circuits affecting the load by checking the wiring from the power supply to the diode.
Using the redundancy module, it is possible for two power supply units of the same type connected in parallel on the output side to increase performance or for redundancy to be 100% isolated from one another.

Features and Benefits

• 100% decoupling of power supply units connected in parallel
• Supports currents up to 30A
• Easy installation by snapping onto the DIN rail
• Reverse polarity protection
• Consistent redundancy up to the load
• Robust design
• Saves space as only 18 mm wide

Typical Applications

The redundant systems are mainly used where the system places a high demand on operational reliability. The PSU must be big enough that the total current requirements of all loads are met by one power supply unit.

Phoenix Contact Diode Redundancy Module, 24V DC Input, 20A Output - TRIO-DIODE/12-24DC/2X10/1X20 - 2866514

Use this diode redundancy module from Phoenix Contact to increase the performance of your power supply units (PSUs) or completely isolate them from one another. As it decouples and isolates parallel-switched units, it prevents short circuits from affecting the load by checking the wiring that runs from the supply to the diode. This ensures high power availability to prevent unnecessary productivity downtimes, which is essential to operational safety and the prevention of electric shocks and fires.
The module automatically takes over entire loads to provide an uninterrupted power supply in the event of failures. It lets you consistently monitor and quickly detect a loss of redundancy thanks to the floating signal contact and LED display, which prevent production interruptions. This compact unit weighs just 370g, so it's easy to handle and install. Use it in systems that demand high operational reliability.

• DIN rail mounting for quick snap-on and space-saving installation
• Reverse polarity protection for device protection when power supply polarity changes
• Wide operating temperatures from -25°C to +70°C for use in heavy-duty environments
• IP20 (ingress protection) rating indicates shielding from finger touch to prevent electrical shocks to handlers
