Product Description:

The PC13802 PC Interface Board is developed and manufactured by Okuma for industrial automation systems. Okuma of Japan made this board, and it provides powerful ways for control units to receive and send signals to peripherals. The terminal blocks carry channel numbers, 24V/0V levels, and X101-X110 labels, showing their digital I/O channels.

The PC13802 interface board has both terminal screws and ribbon cable headers for quick signal connections. It is safely fixed to a printed circuit board using quality components. The board is set up to work with a 24V DC, digital control input. It guarantees clean inputs for digital devices due to its strong noise resistance. What the encoder supports are incremental rotary encoders that have open-collector or line driver output. When fast pulse reading is needed, the encoder input frequency is commonly up to 200 kHz. Configurations determine that the encoder voltage is typically between 5V and 24V. ThePC13802 interface board works well under the common environmental conditions found in industrial automation with CNC. The operation of this processor is not affected when the temperature is between 0°C and 55°C. Safe operation requires a maximum of 95% relative humidity, making sure it doesn’t condense.

The PC13802 interface board remains unaffected by vibrations of up to 0.5 mm amplitude, which occur at frequencies of 10–55 Hz. Machines can be used up to 2000 meters above sea level without problems. Most storage areas maintain temperatures ranging from -20°C to 70°C. The material has a minimum insulation resistance of 100 MΩ when tested at 500 VDC. Circuit to ground insulation between 1500 VAC for a minute is a standard requirement. Response time on I/O is under 10 milliseconds when used for fast control. Because the device is usually less than 500 grams, it is simple to grip and install.
