Channel-Disconnect Switch
Channel-disconnect switch is used to connect or disconnect the digital input and output to the
front I/O connector.
Note
The channel-disconnect switch is controlled through software and the
switching rate is software-dependent.
Short-Circuit Protection
Digital output channels are protected against short-circuit faults.
Note
Short-circuit protection is based on hiccup-mode protection where the control
logic will disconnect the channel using the channel-disconnect switch once short-
circuit fault is detected. This channel will stay disconnected for one second before
the control logic attempts to enable this channel again automatically. However, if the
short-circuit fault is not removed, then this channel will continue to operate in
hiccup protection mode with invalid input or output signal.
