Option card OPT-SIO-1
The option card can provides:
1 general purpose analog input
6 general purpose digital inputs
4 general purpose digital outputs
1 RS485/ RS422 serial port
One analog input with a 12-bit resolution receives a wide range from -10V to +10V.
Six digital input channels are divided into 2 groups. Each group is powered by
separate external power supply and allows the input signal to be connected with
either polarity. All digital outputs share one common external power supply and the
maximum voltage across the outputs when active is 30VDC. Serial port supports
4-wire or 2-wire connections. DIP switch SW2 is used for connecting terminal resistor.
See OPT-SIO-1 option card user’s manual (code:3AXD50000351336) for details.
Note: The firmware build version that supports the option card is MicroFlex e190
Build 5900.4.0 and later.
