Control Units for Gamma System Products
The control units are used to continually control the functionality of pressure sensitive MATS, pressure sensitive EDGES and pressure sensitive BUMPERS. Two safety relays with forced open contacts detect voltage at the leads of sensor terminals (safety mats, edges and bumpers). The control unit is fundamental to continually check the good operation of safety devices. This means being sure that when such devices are activated, the desired electrical signal is generated. The control unit is capable of controlling several safety devices. EN ISO 13849-1 – EN ISO 13856-1-2-3 – EN 60947-5-1 EN 50205 (TYPE A) |

Control units for 8.2kΩ conductive edge
Two symmetric circuits detect the current in the edge, adjusted for a resistance of 8,2 kΩ. When the circuits detect a variation of ± 4 kΩ, caused by a fault or operation of the edge, they desexcite the outlet relays, that open the safety contacts.
