3.1.9 User programmable Discrete I/O (GPIO)

The ACE1553-3U-4 module provides 2 user programmable discrete I/O signals. Discrete input
signals are always active whereas the discrete output signals are per default inactive. An open
collector circuitry is used for the discrete output with approximately 4V provided by default. An
external voltage from 0 to 35V can be supplied externally for switching higher voltages.

Please Note:

The discrete outputs don’t provide a series resistor for over current protection. In case a discrete
input is used, make sure that the output-mode for that discrete is disabled, before connecting an
external voltage, otherwise a high short circuit current to GND can damage the output transistor.

Figure 3.2: GPI/O ACE-1553-3U-x circuitry

Be aware that a series resistor must be provided when a user voltage is used (Figure 3.3). This
serial resistor must limit the current through the open collector transistor to max. current (see
technical data chapter for details). Otherwise the open collector transistor can be damaged.
EMC aspects are covered by filter circuitry.
