The DP-IP-3113 provides economical method for interfacing digital I/O signals. It supports continuous data rate of 8MB/s on word access and 4MB/s on byte access. All I/O’s are RS232 compatible which is differential standard providing high noise immunity.
Field inputs are provided with debounce circuitry that offers programmable time delays. The debounce clock can be programmed from 125ns to 8ms in binary steps. Hand shake signals are provided using input strobe, data acknowledge and output trigger for inter system communication.
Features:
- 16 channels of differential I/O’s
- Programmable interrupts
- Programmable debounce time
- Built in self test
- Register programmable TTL / CMOS
- Selectable interrupt masking for all channels
