Connecting a Counter /
Incremental Encoder
The connection of "Signal A", "Signal B" and
"Reset" is possible at any digital line.
Make sure to configure the relating digital
lines as input and to assign them to the
counter.
3.2
Interfacing Examples for Digital Outputs
Serial resistors in the output lines limit the current and protect the hardware from being destroyed.
3.2.1
Connecting an LED
Only so-called low-current LEDs can be
used, because they already work with
1mA current.
Please also observe the total current
listed in the technical data (see chapter
0).
3.2.2
Connecting a Relay
A connected relay is ideal to switch
higher currents. Since the field coil of the
relay requires a higher current than
provided by the measurement system at
one line, a transistor is connected ahead.
Relay cards featuring 8 outputs are
available at bmcm.
