The Safe Speed Monitoring Module is able to connect to two sensors with PNP outputs. It features output relays that de-energizes when speed exceeds set value for over-speed monitoring and energizes output relays when speed drops below set value for under-speed monitoring. It also features feedback input monitors for external machine control systems with a 24V ac/dc operation. It is equipped with a 45 mm DIN-rail mountable wide enclosure with a removable terminal blocks with two the same forced guided output contacts rated at 4A, plus one auxiliary N.C. output contact.
