10.1Digital 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 kΩ

 

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.

Solid-state contact (option)

Photo-coupler (option)

Resistor (option)
