Description
Rexroth HSZ01.1-D08-D04-NNNN safety module — description and application
The Rexroth HSZ01.1-D08-D04-NNNN safety module is a brand new (factory new), unused industrial automation component bearing the Bosch Rexroth logo. The housing carries the "SAFETY ON BOARD" marking, indicating that the device performs machine-safety functions – most likely as a safety I/O module working with a central control unit or a safety controller within a Rexroth system. The product is aimed at maintenance departments, system integrators, and service companies involved in the modernisation and repair of control cabinets for production machinery.
The exact function of the module within the safety architecture (e.g. monitoring of E-Stops, safety guard doors, light curtains) needs to be confirmed in the manufacturer's technical documentation – the "D08-D04-NNNN" designation in the part number suggests a specific input/output configuration whose full meaning remains to be verified by the buyer.

Applications
Modules of this type are used in safety systems of production machinery, assembly lines and control cabinets wherever safety functions need to be monitored in line with the Bosch Rexroth control architecture. The Rexroth HSZ01.1-D08-D04-NNNN safety module can be applied in the machine-building and automotive industries, as well as in industrial automation installations that require integrating safety functions with the central control system. Compatibility with the target system should be verified before ordering.
Condition and scope of delivery
This unit comes from surplus stock (new-old-stock) – it is a fully functional, brand new (factory new) component, unused and never installed, supplied in the manufacturer's original packaging with a Bosch Rexroth shipping label (packing date 06-03-23) and ESD marking protecting the electronic components. The photos show the original label with the full catalogue number, material number and serial number. Products like this are often unavailable through regular distribution or involve long lead times when ordered from the manufacturer, so a surplus-stock offer shortens the delivery time. Buyers should review all photos, as they form an integral part of the product description.
