ELM381 Datasheet (ELM Electronics) - 60Hz Long Interval Counter

ELM381, 60Hz Long Interval Counter

The ELM381 is a digitally configurable, multistage counter circuit in a single 8 pin package.

When connected to a 60Hz source, four time periods from one hour to one week are possible, as shown in Table 1 below.

Although the circuit has been optimized for a 60Hz input frequency, it is capable of bei
