PILZ 773400 PNOZ mi1p – 8-Channel Safe Input Expansion Module | PNOZ multi 2 Platform
The PILZ 773400 PNOZ mi1p is a dedicated safety input expansion module engineered for the PNOZ multi 2 modular safety controller platform. Designed to extend the safe input capacity of a base unit, it enables procurement engineers and system integrators to scale safety architectures without replacing the core controller — delivering certified functional safety at the field level for machinery, robotics, and process automation.
Konmask.com supplies the PILZ 773400 from verified distribution channels, with full traceability documentation available on request. Suitable for OEM builds, retrofit projects, and safety-critical production lines requiring IEC 62061 SIL 3 or EN ISO 13849-1 PLe compliance.

Proven Application Environments
- Industrial Robotics: Expanding safe input channels for multi-axis robot cell guarding, two-hand control, and enabling device monitoring.
- Press & Stamping Machinery: Connecting additional E-stop buttons, light curtains, and safety mats beyond the base unit’s native I/O capacity.
- Conveyor & Material Handling: Monitoring multiple zone-entry sensors and pull-wire switches across extended conveyor lines.
- Packaging Machines: Integrating door interlock switches and safety edges on multi-door enclosures.
- Process Automation: Acquiring safe digital signals from field devices in SIL 3-rated process safety loops.
- AGV / Mobile Platforms: Monitoring bumper sensors, laser scanner outputs, and emergency stop circuits in autonomous guided vehicles.
Engineering Advantages
- Seamless Scalability: Plug directly onto any PNOZ multi 2 base unit via the integrated system bus — no additional wiring harness required.
- Certified SIL 3 / PLe: Meets the highest functional safety standards, eliminating the need for external safety relays on each input channel.
- Compact 22.5 mm Profile: Minimizes control cabinet footprint when multiple expansion modules are stacked.
- Unified Configuration: All I/O logic is programmed within PNOZmulti Configurator software — no separate module configuration tool needed.
- Diagnostic Transparency: Per-channel status LEDs and software-readable diagnostics accelerate fault isolation during commissioning and maintenance.
- Wide Certification Portfolio: CE, UL, cUL, and TÜV approvals support global machine export compliance.
System Architecture & Signal Flow
The PNOZ mi1p connects to the right-hand side of a PNOZ multi 2 base unit (e.g., PNOZ m B0, m B1) via the proprietary system bus connector. Safe input signals from field devices (E-stops, light curtains, interlocks) are wired to the module’s screw terminals in 1- or 2-channel configuration. The base unit’s safety CPU reads all input states over the internal bus, evaluates the safety logic defined in PNOZmulti Configurator, and drives output modules accordingly. Up to 8 expansion modules can be connected per base unit, providing up to 64 additional safe inputs in a single safety controller node.

Technical FAQ
Q: How many PNOZ mi1p modules can be connected to one base unit?
A: Up to 8 expansion modules (mix of input and output types) per PNOZ multi 2 base unit, subject to the base unit’s power budget.
Q: Is the PNOZ mi1p compatible with PNOZ multi (first generation)?
A: No. The mi1p is designed exclusively for the PNOZ multi 2 platform. First-generation PNOZ multi uses a different system bus and is not compatible.
Q: Can inputs be configured as single-channel (1oo1) or dual-channel (1oo2)?
A: Yes. Each input pair can be configured independently in PNOZmulti Configurator as 1-channel or 2-channel (equivalent/complementary) depending on the connected device and required safety level.
Q: What is the maximum cable length for safe inputs?
A: PILZ recommends a maximum of 100 m for standard 24 V DC input wiring. Shielded cable is recommended in high-EMI environments.
Q: Does this module require a separate 24 V DC supply?
A: No. The PNOZ mi1p draws its operating power from the PNOZ multi 2 system bus. Only the field-side input signals require an external 24 V DC source.
