Input Connections

Input Connection Contact Input

When the H7EC-NP is used, relay chattering may be counted. Use
the H7EC-NLP, one of the low-speed input models.

Solid State Input

Use a transistor for input that satisfies the following conditions:

Collector breakdown voltage

≥

50 V

Leakage current < 1

Use a diode (D) having a forward voltage as small as possible (0.1 V
max. at I

of 20

A).
