Selection Guide
Use the following criteria to confirm the 2320157 is the correct module for your application:
- System voltage: 12 VDC or 24 VDC nominal? → 2320157 supports both.
- Per-channel current: ≤ 20 A per power supply? → Confirmed compatible.
- Total load current: ≤ 40 A? → Within rated output.
- Mounting: 35 mm DIN rail available? → Standard fit.
- Diagnostics required: Need error signaling? → Built-in collective error contact included.
- Upgrade path: Planning to migrate to QUINT4? → Consider 2866594 for forward compatibility.

Replacement & Compatibility FAQ
Q: Can I replace the 2320157 with the QUINT4-DIODE 2866594?
A: Yes, the QUINT4 series is the next-generation successor. It is electrically compatible but has a slightly different housing profile. Verify DIN rail space before installation.
Q: Is the 2320157 compatible with non-Phoenix Contact power supplies?
A: Yes, as long as the power supply outputs 12–24 VDC at ≤ 20 A per channel with standard terminal connections.
Q: What is the difference between 2320157 and 2320170?
A: The 2320170 is rated for 24 VDC fixed input only, while the 2320157 supports 12–24 VDC. Choose 2320157 for mixed-voltage or legacy 12 V systems.
