MSC is a modular safety controller for protecting machines and personnel. MSC is capable of monitoring several safety sensors and commands, such as safety light curtains, non-contact switches, photocells, mechanical switches, zero-speed monitoring, safety mats, emergency stops, two-hand controls. MSC-CB base unit with 8 inputs, 2 digital outputs and 2 pairs OSSD outputs can run stand alone or can be expanded. A single MSC-CB base unit can control several remote expansion modules. The MSC 'Euchner Safety Designer' Software with timing, counting, logical and memory operators, communications and muting options is provided at no extra cost with every MSC-CB base unit.
