DIO-1616B-LPE
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
* O-xx represents the output pin.
Figure 3.5. Output Circuit
The output circuits of interface is illustrated in Figure 3.5. The signal output section is an opto-
coupler isolated, open-collector output (current sink type). Driving the output section requires the on-
board internal power supply or the external power supply.
The rated output current per channel is 100mA 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 0.5V or less at an output current within 50mA or at most 1.0V at an output current within 100mA.
A zener diode is connected to the output transistor for protection from surge voltages. A overcurrent
protection circuit is provided for every 8 output transistors.
