[Description of J5 connector]
PCIe-FRM11 Board has six photo-coupler isolated digital inputs and four equivalent outputs. Each
is available from J5 connector. The equivalent circuit is as shown Figure [3-5].

[Figure 3-5. Photo-coupler Input/Output Circuit]
The input resistance is 2.4K ohms thus the flow current is about 5mA when 12V input is applied and
about 10mA when 24V power applied. Maximum operation input voltage is from 9V to max 24V.
The output current is limited by output resistance, the output resistance is 22 ohms. Continuous
output current has to be used under 10mA. The user can change the Input/Output resistance for special
operation.
The pin map of the connector is shown below.
