Connecting Output Signals
Connect the output signals to a current-driven controlled device such as a relay or LED.
The connection requires an external power supply to feed currents.
The board controls turning on/off the current-driven controlled device using a digital value.
Output Circuit
* Output pin represent output signals.
Figure 3.13. Output Circuit < DIO-3232L-PE >, < DO-64L-PE >
The output circuits of interface blocks of the < DIO-3232L-PE >, < DO-64L-PE > is illustrated in
Figure 3.13. The signal output section is an opto-coupler isolated, open-collector output (current sink
type). Driving the output section requires an external power supply.
The rated output current per channel is 100 mA at maximum.
The output section can also be connected to a TTL level input as it uses a low-saturated transistor for
output. The residual voltage (low-level voltage) between the collector and emitter with the output on
is 0.5 V or less at an output current within 50 mA or at most 1.0 V at an output current within 100 mA.
To protect against surge voltage, a Zener diode is connected to the output transistor. Also, an
overcurrent protection circuit is attached to a unit of eight output channels.
When the PC is turned on, all output are reset to OFF.
