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 | |
| 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
