Relay Output

Through the connector marked Relay Output
page 28) you may utilise the floating relay contacts for switching functions and for error
monitoring.

NOTICE:
Contact 25 serves the purpose of powering relays with a higher switching
capacity. The contact is protected by means of a PTC resistor limiting the
maximum current to 200 mA. The PTC resistor is self-resetting when
switching the instrument off or pulling the plug out of the socket marked Relay
Output.
DANGER: Dangerous voltage
Voltages exceeding 60 VDC or 30 VAC are dangerous when touched. You
may only switch at the connector marked Relay Output voltages of 30 VDC or
30 VAC with a maximum current of 1 A. The voltage must comply with the
requirements of a safety extra-low voltage (SELV-E in accordance with EN
61010).
Connecting:
 Connect the peripheral components using a shielded connecting cable to the connector
marked Relay Output on the rear of the GRAPHIX controller.
