Applications
You can use the C 579 expansion unit in combination with all the C 57x basic units. It extends the number of release circuits. Depending on the external connection, category 4 as per DIN EN 954-1 is achievable with this device.
Functions and connections
The C 579 expansion unit has four release circuits (safety circuits) confi gured as NO circuits. Two LEDs indicate operating state and function. The device is controlled via any release circuit of the safety relays C 57x. When the EMERGENCY STOP pushbutton or the limit switch is unlocked and the ON button is pressed, the internal circuit of the safety relay and the external contactors are checked for correct functioning.
