Product Introduction
The Pilz 301130 (PSS SB DI16) is a 16-channel fail-safe digital input module for Pilz SafetyBUS p safety systems. It reads the status of safety devices such as emergency stops, safety gates, and light curtains, and passes that information to the PSS SB CPU for safe logic processing.
This module is chosen in legacy PSS SB installations where engineers need a direct, pin-compatible replacement for existing DI16 cards. It supports automatic test pulsing for wire-break detection and integrates cleanly into existing SafetyBUS p networks without reprogramming the safety logic, as long as the hardware configuration matches the original design.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No LEDs on module, system shows “module missing” on SafetyBUS p | No 24 VDC supply to rack or module not seated | ✅ High | Measure 24 VDC at rack power terminals; check backplane connection; verify module is fully clicked into slot | Restore rack power and reseat module; if still dead, suspect failed PSU or module |
| ERR / module fault LED on, SafetyBUS p shows configuration error | Firmware/hardware mismatch, damaged module, or wrong slot configuration in safety project | ✅ High | Check PSS SB CPU diagnostic buffer in PNOZmulti / PSSwin; compare configured slot type with physical module | Correct project configuration; if error persists with correct config, replace module |
| Some inputs never go active, even with field device energized | Blown input channel, wiring fault, or test pulse configuration mismatch | ✅ Medium-High | Use multimeter to verify 24 VDC at input terminal when device is active; compare with LED status on module | Repair wiring first; if voltage present but LED off, suspect failed input channel on module |
| Intermittent input flickering | Loose terminal screws, noise on 24 VDC, or failing power supply | ❌ Low-Medium | Check terminal tightness; measure 24 VDC ripple with oscilloscope or AC-coupled multimeter | Fix wiring and grounding; only replace module if issue follows the card when moved to another slot |
| Entire SafetyBUS p segment drops out after adding this module | Overloaded backplane power or short on module | ✅ Medium | Measure total rack current draw; disconnect module and see if bus stabilizes | Reduce load or replace PSU; if bus works without this module but fails with it, module may be internally shorted |
If you’re stuck, send photos of the module, rack layout, and a screenshot of the SafetyBUS p diagnostic buffer. That usually cuts diagnosis time in half.
Frequently Asked Questions (FAQ)
Q: Is the Pilz 301130 (PSS SB DI16) still available new from Pilz?
A: According to Pilz’s own e-shop, the 301130 PSS SB DI16 is listed as “no longer available” as a new item. What you’ll find on the secondary market is new surplus, open-box, or refurbished units. That’s why lead times and condition matter more than with current-series modules.
Q: Can I hot-swap this module in a running PSS SB system?
A: No. The PSS SB platform is not designed for hot-swapping safety I/O modules. Powering the rack while inserting or removing modules can cause bus errors or even damage the backplane. Always shut down the 24 VDC supply to the rack before swapping the 301130.
Q: Will this work as a direct replacement for my existing PSS SB DI16?
A: Yes, if your existing module is also a 301130 PSS SB . The hardware and pinout are identical, so you can swap it one-for-one. You still need to verify that your safety project configuration in the CPU matches the physical slot and module type, especially if the original card was replaced or moved in the past.
Q: Do I need to reprogram my safety logic when replacing this module?
A: In most cases, no. The safety program lives in the PSS SB CPU, not in the module. As long as you install the same module type in the same slot, the existing project should come up without changes. If the CPU reports a configuration mismatch, compare the hardware config in the project with the actual rack layout and adjust if needed.
Q: What condition are these modules in, and why are they cheaper than factory new?
A: These are refurbished (tested) units pulled from decommissioned systems or surplus stock. They’re cleaned, visually inspected, and functionally tested on a live PSS SB rack with SafetyBUS p. Because they’re not factory-sealed new and the series is obsolete, they trade at a lower price than original Pilz list.
Q: What warranty do you offer on the Pilz 301130?
A: Standard warranty is 1 year from shipment against functional failure under normal industrial use. If the module fails within that period and shows no signs of misuse (overvoltage, water damage, ESD burns), we replace it or refund, your choice.
Q: How do you test these before shipping?
A: Each 301130 is installed in a genuine Pilz PSS SB rack with a known-good CPU and SafetyBUS p network. We verify: 24 VDC power-up, module recognition on the bus, LED status for all 16 inputs, and basic test pulse operation. A simple test report (pass/fail + photos) is available on request.
