Buffered AI Trigger & CLK Source

The ECU-P1706 has a double-clock system, with a 

SCAN clock and CONV clock, to generate efficient 

A/D conversion clocks at specific times. A/D 

conversion clocks come from internal clock sources 

or external signals on a connector. The CLK has 

several sources.

 

ƒ

Internal A/D clock derived from 32-bit divider 

 

ƒ

External A/D clock from terminal board 

With ECU-P1706, user can define the type of trigger 

source as rising-edge or falling-edge. The Trigger has 

several sources.

 

ƒ

External digital (TTL) trigger from terminal 

board

One-shot Connection

When the Gate pin receives a trigger, Counter begin to 

count using internal clock or external clock. The Out 

pin output a pulse or Toggled signal after the counter 

count the number of delay count that can be set by user.
