Wiring Example of External Control Inputs
Section 3-5
Example 5: With Encoder
Conversion Adapter
In the following example, open collector outputs from an encoder is connected
as line driver inputs through the C500-AE001 Encoder Conversion Adapter.
Note
Connect the wires so that a counter input to the High-speed Counter Unit will
be turned ON when an output from the encoder is turned ON.
The C500-AE001 Encoder Conversion Adapter uses an Am26LS31-compati-
ble line driver. H will be output to the positive terminal and L will be output to
the negative terminal of the C500-AE001 when an input to the C500-AE001 is
H.
