B.6.2 Wiring requirements
The operating threshold for the auxiliary I/O port inputs is set in the configuration of the
unit and can be either:
•
5 V: ON by 2 V, OFF by 0.8 V (TTL)
•
24 V: ON by 14.5 V, OFF by 5.8 V
Thermal fuses protect the 24 V and 5 V supply outputs – to reset a fuse, remove the
power from the RCU10 unit for a number of seconds. All signal pins (both input and
output) are fully protected against a direct connection of an external supply, up to ±30 V.
