All the digital inputs and outputs are TTL. Under normal operating conditions, the voltages on the I/O pins range from near 0 volts for the low state, to near 5 volts for the high state. The voltages and currents of external devices usually exceed these values. Because of this, external relays are usually employed to handle higher current and voltage loads.

In addition to load matching, digital signal sources often need to be filtered or "de-bounced". Refer to the Guide to Signal Connections for information on digital interfacing. This document is available at www.mccdaq.com/signals/signals.pdf
