Introduction

The ET-7259M-16 provides 16 AC/DC digital input channels. Each input channel can be used as a 32-bit counter. It features optical isolation for 2500 VDC of transient over voltage protection but doesn't provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present.
