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 kΩ

Number of inputs

• 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.
