Output Circuit
Output circuit
The output circuit of these boards is illustrated in the
following figure. The output channel is a photocoupler-
isolated open-collector (sink type). You need an additional
power supply that is isolated from the PC to drive these
insulation circuits. The maximum output current ranting is
100mA per channel.
