INPUT/OUTPUT SIGNAL SPECIFICATIONS
The input/output signals wired to the J1 through J4 connectors can be grouped by type as
follows; their electrical characteristics are discussed below.
• Digital inputs
• Digital outputs
• Analog inputs
• Analog outputs
• Power
• Communications ports
Digital Inputs
These signal lines can be used as digital (ON/OFF ) inputs. Normally, the ON signal is made by
a connection direct to B+ and OFF is direct to B-. Inputs 1 through 18 will pull low (OFF) if no
connection is made. Inputs 19 through 26 will pull high (ON) if no connection is made.
Inputs 1 through 18 are associated with driver outputs. Inputs 19 through 26 are low voltage
“TTL” level inputs and can be used when connecting to other low voltage (5v) logic circuits or
sensors. The encoder channels are normally used for pulse count inputs from quadrature (2
channel) encoders, but they may also be used as 5v logic level digital inputs. Take careful note
of their much lower voltage range.
