I/O OPTIONS

■ Event Trigger Input: Dry contact or NPN open collector

Input current: ≤ 3 mA

Sensing: 6 V

Contact detecting: ≤ 1.5 V at ON; ≥ 3 V at OFF

Signal ID and Details

S_TMR: Startup Timer

Measuring starts in the predetermined time after

detecting the signal turning on.

TIMING: Timing

Used for various timing hold functions

ZERO: Forced Zero

Not used

HOLD: Hold data

Reading measured signal stops and the last value is held

when HOLD signal is turned on.

RESET: Reset data

The device is reset when RESET signal is

turned on.
