JPX A and JPX B select isoiated
or non-isolated
|
|
JPOB to JP7B are used to select isolated
or non-isolated. When JPXB-1, JPXB-2 is sort, then the corresponds channel
is in isolator mode. When JPXB-2, JPXB-3 is short, the IxL is short with
system GND. So the external signal is in non-isolated mode. JP0A to JP7A
are used to select power signal input or non-power signal input for the
correspond channel. JpxA-1 and JpxA-2 short is power signal input mode. JpxA-2,
JpxA-3 short is non-power input mode.

JP 17 Internal / External power selection |
|
User may use jumpers to select external
or internal power supply. When the input signal is non-power signal (e.g.
Switch etc��), internal power is selected; user can select the PC bus power
+12V or 5V. When the input is voltage or current, the external supplier
is mean the signal itself that can adjust from +5V to +30V.
|
JP17 is
used to select internal or external power supply of input channels. When
JP17-1 is shorted, the PC bus +12V power is selected, when JP17-2 is shorted,
the PC bus +5V power is selected. If we short JP17-3, then the external power
supplier is selected.
