Modular safety relay
myPNOZ
Between a single relay and a configurable controller sits a gap: several safety functions that interact, but not enough to justify programming. myPNOZ fills it — a modular relay assembled to your specific combination of functions and produced individually in batch size 1, configured in a browser rather than in an engineering tool.

Why it is specified
Effect of the modular approach
The value is in matching the device to the function list exactly, without either wiring several relays together or moving to a programmed controller.
Built to the function list
Produced individually in batch size 1, tailor-made to the stated requirements.
Wide application range
From a small application with just two safe input functions to larger applications with up to 30 input functions.
Configured, not programmed
The myPNOZ Creator defines the assembly online, so no engineering software or programming skill is required.
Adaptable over life
The modular design means the relay is flexible to adapt and expand at all times.
Applications
myPNOZ is used
The manufacturer states the modular relay covers a wide range of applications and can be used on almost any automated plant.
Relay consolidation
Replacing a wall of relays
Existing panels where functions were added one relay at a time until the wiring became difficult to follow or to modify.
ConfirmConfirm existing devices and circuits.
Series machinery
Repeatable machine builds
A defined function combination repeated across a machine range, where the same assembly can be ordered again reliably.
ConfirmConfirm the standard function set and quantity.
Technical data
Selection parameters that matter
myPNOZ is specified by its function list rather than by a single part number. These are the parameters that shape the assembly.
Because the device is built to order, the function list must be complete and correct before the assembly is defined.
| Concept | Modular safety relay produced individually in batch size 1, tailor-made to requirements |
|---|---|
| Application range | From two safe input functions up to 30 input functions |
| Configuration | Defined in the myPNOZ Creator online tool |
| Programming | No programming required — the assembly is configured |
| Module widths | Modules from 12.5 mm and 17.5 mm |
| Flexibility | Modular design allows the relay to be adapted and expanded |
| Scope | Covers a wide range of applications on almost any automated plant |
| Ordering | The configured assembly is ordered as a defined build |
The combination logic is fixed by the assembly. Where functions must be changed frequently, or where diagnostics and communication are required, review PNOZmulti 2 instead.
Models
Assembly definition
The build is decided by the function list, so the specification work happens before the order rather than after it.
Scale
2 to 30 input functions
The number of safe input functions is the primary sizing parameter for the assembly.
- Minimum
- 2 functions
- Maximum
- 30 functions
Modules
12.5 and 17.5 mm
Module widths determine the overall width in the panel once the function list is fixed.

Configuration and integration
The main dependency is the function list; beyond that, the relay integrates like any other evaluation device.

Before quotation
Application review
Because the device is built to order, the function list carries the whole specification. Getting it complete is the main task.
Function list
- Every safety function to be evaluated, with its input device
- How many safe input functions in total
- Which functions interact, and how
- Required performance or integrity level, if determined
Inputs
- Type of each input device and its output arrangement
- Single or dual channel per function
- Whether any devices are connected in series
- Cable lengths and connection method
Outputs
- Number of safe outputs required
- Stopping element for each output group
- Whether feedback loop monitoring is required
- Required stop category per function
Panel and lifecycle
- Available panel width for the assembly
- Supply voltage
- Expected future changes to the machine
- Quantity and repeat-order requirement

myPNOZ sits in the architecture
It occupies the middle ground: more capable than a single relay, simpler than a configurable controller. The boundary is usually diagnostics and the expectation of change.
