PCU/1 is a modular, configurable safety controller for protecting machines and plants. PCU/1 is capable of monitoring several safety sensors and products, such as safety light curtains, safety edges, safety bumpers, ribbon switches, laser scanners, photocells, mechanical switches, mats, emergency stops, two-handed controls, concentrating managment of these in a single, flexible device.

The PCU software, installed on a PC, can be used to create complex logical conditions using logical operators and safety functions, such as muting, timer, counters, memories, etc. via an easy, intuitive graphic configuration interface. Configuration data are transferred to the PCU/1 unit via a USB link. Expansion modules are available for larger installations.
•  Reduces the number of components and thus reduces footprint and wiring
•  Promotes faster electrical cabinet construction
•  Affords the necessary logical configuration using a single, simple programming software, facilitating modifications by
    machine designers
•  Makes it possible to setup tamper-proof safety systems
•  Simplifies machine maintenance through the PCUMCM/1 memory card, which can be used to transfer the configuration
    program to a new PCU/1 in just a few simple steps.

This response times depends on the
following parameters:

1) Number of slave modules installed
2) Number of operators
3) Number of OSSD outputs

For the right response time refer to the one
calculated by the PCU software (see Project
report)
