Counter Input
The counter input serves for connecting a pulse encoder which is required when
using a belt scale in continuous operation. Twisted pair wiring should be used for
the connections.

Digital Outputs
The SIWAREX FTC has eight potential isolated outputs (DO) with a nominal
voltage of + 24 V and an output current of maximum 0.5 A per output (max. total
current 2 A).
These outputs are potentially isolated from the module group. The outputs share
common potential. They have a common ground and a secure 24 V supply.
They are short-circuit and overload protected.
DO status is indicated with and LED on the front of the SIWAREX FTC.
When connecting inductive consumers, the digital output that is used must be
equipped with a free-wheeling diode.
