Description
Connection point for the digital outputs’ customer power supply and the relay contacts. Relay rated at 1A, 24VDC
The relay and user power connector X5 provides a connection point for the internal relay, the customer power supply used to power the digital outputs, and the digital input’s common connection. Power connections are assigned two pins to provide increased wiring capacity. The USR V+ and CGND connections on pins 5/6 and 9/10 are connected internally to the USR V+ and CGND pins on connector X4 - see section 4.6.4.
The relay outputs are isolated from any internal circuits in the NextMove BXII. The relay is controlled by a latch, which is cleared when the NextMove BXII resets. Reset can occur due to
The relay can be configured as a global error output using the Mint keyword
GLOBALERROROUTPUT.
