The present invention relates to a digital block apparatus having excellent compatibility. An objective of the present invention is to provide a digital block apparatus having excellent compatibility in which a malfunction signal, a rail signal and a signal of a signaling device are implemented in a digital electronic control scheme based on not relay logic but a CPU, so that a signal is exchanged with a commercial automatic block apparatus including three-phase, four-phase, five-phase, a signal line or duplicated lines, so the digital block apparatus has a small size, is economically excellent and has a low error rate. When the digital block apparatus of the present invention is applied, the digital block apparatus can exchange a signal with a commercial automatic block apparatus including three-phase, four-phase, five-phase, a signal line or duplicated lines, so that the digital block apparatus has excellent compatibility, a small size and has a low error rate, and is very economically excellent.
