MZERO
The smart solution for industrial safety
MZERO: Stand alone configurable safety controller
Compact and configurable Safety controller. Bringing full configuration capabilities at the cost of a standard Safety relay.
In the world of industrial automation, safety is not an optional extra, but a fundamental necessity. MZERO was created to meet the market need for a complete, simple and economical solution, even in situations where there is machinery already in operation and retrofitting or a simple upgrade is required.
MZERO configurable safety controller
Key features
MZERO is a stand-alone configurable safety hub able to manage all safety functions of a machinery or a plant allowing cost reductions and minimal wiring.It is designed to ensure simple installation, with significant savings in both cost and time. With its compact design, MZERO makes it possible to reduce wiring and manage safety with a single device, in situations where a safety controller and its expansion would be required.
MZERO can manage safety sensors and signals such as:
Light curtains, photocells, laser scanners, emergency stops, electromechanical switches, guard-lock door switches, magnetic switches, RFID switches, mats and edges, two-hands controls and hand grip switches.
Main features
A. 16 digital inputs for safety device management
B. 4 inputs for EDM and restart functions
C. 4 pairs of safety OSSD outputs (PNP 400 mA) up to SIL3 PLe with integrated protection
D. 4 status outputs (PNP 100 mA) SIL1 for system monitoring
E. 4 test outputs to check for short circuits on electromechanical devices
F. 64 logic operators for customizable configuration
G. Dedicated MZD software for fast and intuitive programming
H. USB Connection – USB 2.0 serial bus for the connection to Mosaic Safety Designer (MSD) software
I. Removable terminals – Two versions available with clamp contacts or with screw contacts
MZERO Advantages
Compared to “traditional” electromechanical safety-relays-based safety circuitries, MZERO has the following advantages
Project optimisation
- Reducing the number of devices and wiring used and, therefore, the overall size of the project
- Speeding-up control panel construction
- Simply adding or removing safety function blocks at any stage of machine design
- Allows tamper-proof system configurations as:
detection of tempering attempts through specific tests (i.e. mandatory test of the safety device at machine start-up)
Protection against unauthorized changes to the project through a 2-level password - All logic is configured through a graphic interface. No more laborious wiring is needed as with traditional solutions
- A lower number of electromechanical components also means a better Performance Level and, therefore, a higher Safety Level
MZD software
- MZERO is configurable via the MZD (MZERO Safety Designer)
- MZD is a graphic interface configuration software (provided with each units at no extra cost)
- Providing logic configuration via a quick and easy-to-use software. Machine designers are always able to change configuration logic
- MZD is able to check the logic configuration of the application during the designing phase through the validation
- Function and Simulation as well as to test it during the installation through the monitor function
- The project report provides the actual values of PFHd, DCavg and MTTFd according to EN 13849-1 and EN 62061
When is it worth choosing MZERO?
MZERO is the perfect solution for those who need to manage several safety devices while having limitations in the control cabinet. It is especially advantageous for those who need to manage up to 20 inputs*, offering a cheaper alternative with less wiring.
*If more than 20 inputs are required, the master unit + expansions solution may be needed. Contact ReeR to find out which solution is best for you.

Success story
From theory to practice: the Meccanotecnica case
Meccanotecnica, a company based in Torre de‘ Roveri (BG), specializes in the production of groups and lines of automatic thread stitchers and industrial bookbinding machines from offset and digital printing. They have chosen MZERO controllers to easily and effectively manage the safety devices installed along their production line.
Specifically, the MZERO controller is used on the Multiplex, an automatic book collecting and stitching line. The line consists of MX4 picker modules connected to three stitching units (asterPRO, aster-PRO/52 or asterTOP). The system can be configured with up to 8 modules and used by one or two operators.
Each module of the Multiplex picker is equipped with a MZERO controller that controls 4 RFID sensors attached to the movable guards plus an emergency button and communicates through the module’s local PLC via a coded digital output of the MZERO itself.
The different MZEROs are connected to each other and with individual devices, fewer wiring and power supply cables needed manage to ensure safety control along the entire line.
Configuration and use:
- Each module of the Multiplex harvester is equipped with a MZERO controller.
- The system can be configured up to 8 modules.
- For each module, 4 RFIDs are connected for guards and an emergency button.
Communication and diagnostics:
- Diagnostics between MZERO and the module’s local PLC is via a coded digital output of the MZERO.
- This allows the safety status of the module to be monitored accurately and effectively.
Main function:
- The MZERO manages machinery safety by monitoring access to guards and activation of emergency buttons.
- It ensures compliance with safety regulations, reducing operational risks.
