10.1 Digital I/O Specifications
The specifications of the digital I/O terminals of the LF232 converter are as follows:
Digital Outputs:
(DO1) Output type Transistor open collector (standard)
Number of outputs 1
Capacity 30 VDC, 200 mA maximum
(DO2 to DO4) Output type Solid-state contact output (non polarity) (option)
Number of outputs 3
Capacity 150 VDC, 150 mA maximum
150 VAC (peal value), 100 mA maximum
Digital Input (option):
(DI1, DI2) Signal type Voltage signal of 20 to 30 VDC
High input level: 20 to 30 VDC
Low input level: 2 VDC maximum
Input resistance Approx. 2.7 k
Number of inputs 2
Each terminal can be set to select each function.
Terminal “CO2” is the common terminal of DO2 to DO4 and “CI” is the common terminal of DI1
and DI2.
Each terminal is isolated from internal circuit.
(Output terminals are not isolated between them.)
In the case of the standard specification (without digital I/O specification), a solid-state contact,
photo-coupler and resistor are not provided internally.
