Product Description
Using common-cathode diodes, it prevents back-feeding from a failed supply and provides near-seamless switchover, improving availability in critical control systems. In redundancy mode each channel is rated 20 A, while in capacity-expansion mode the combined output supports up to 40 A. The Phoenix Contact 2320157 is the QUINT-DIODE/12-24DC/2X20/1X40 diode redundancy module, used to decouple two independent 12-24 V DC power supplies so that either one can carry the full load.
Basic Product Information
- Redundancy mode: 2 x 20 A channels; capacity-expansion mode: 1 x 40 A output
- High efficiency above 97% with low power loss (about 10 W at 20 A)
- Reverse-polarity, overload and short-circuit protection
- Collective error message contact for remote signalling
- DIN rail mounting, IP20, screw connections
- Decouples two 12-24 V DC power supplies via common-cathode diodes
Technical Specifications
Version & Model Difference
The 2320157 is the 12-24 V DC, 2x20 A / 1x40 A diode redundancy module of the QUINT range. The fixed 24 V DC variant is 2320170, and the next-generation equivalent with enhanced diagnostics is 2907719 (QUINT4-DIODE/12-24DC/2X20/1X40). Verify voltage, per-channel current and mounting space before substitution.

Frequently Asked Questions
What does the Phoenix Contact 2320157 do?
It is a diode redundancy module that decouples two 12-24 V DC supplies so one can take over seamlessly if the other fails.
What are the current ratings of the 2320157?
In redundancy mode it is rated 2 x 20 A, while in capacity-expansion mode the single output supports up to 40 A.
Is the 2320157 for 24 V DC systems only?
No. It accepts a 12-24 V DC nominal input with a wide 10-30 V DC range.
Is there a newer replacement for the 2320157?
Yes, the QUINT4-DIODE/12-24DC/2X20/1X40 (2907719) is the next-generation equivalent with enhanced diagnostics.
