Output Hardware Connection
Output Example:
Shown in the example below is the equivalent MReX internal electronics of the output that is shared
with input 1. The output is an open collector suitable for sinking a maximum of 50mA. The ex-
ample is being used to drive an LED from an external supply. Should the output be presented to po-
tential ESD conditions (such as any terminal screw or external connection), ESD devices should be
fitted. If the output is to be used to control a small relay, it is essential that a flyback diode is fitted
across the coil of the relay.
