4.6.1.2 Fieldbus Net Box and Optional Solid State Threshold Relay
The solid-state relay is standard on the fieldbus Net Box.
The optional solid-state threshold relay has a quicker activation time than the
standard threshold relay and no moving parts to wear out.

The solid-state relay can operate at up to 30VDC and at a maximum current of
35mA. The relay can turn on within 500µs of a trigger load. The output is reverse
polarity protected to up to 1A (V r = 1.5V), 47V. The maximum delay from threshold
condition trigger to relay conduction is 500µs.
