Main Page / Machine Automation / Analog Timers

Analog timers provide an excellent low cost alternative to digital set point versions.

Analog timers by Autonics offer LED indication when timing (flashing LED), and when the elapsed time has reached the set point (solid LED).


The AT series offers 3 models to choose from:

AT8A: On-delay function, 2 normally open time limit contacts
AT11D: Four step operation, 2 normally open timed contacts
AT11E: Four step operation, 1 instantaneous, and 1 timed contact

Operating Modes
Features and Benefits

A.

Starts timing on leading edge of start signal.
Output is given when elapsed time is equal to preset time.
Output will remain on until reset or power is interrupted.

time limit is easily selected by turning the front timing ring
the time range available is from 0.05 seconds to 100 hours (all on one timer)
one LED shows timing state
panel, DIN rail, or surface mount
various functions available (on-delay, off-delay, flicker, on/off delay)
very cost effective

B.

Starts timing on leading edge of start signal.
Output will be off for the set time, and then on for the set time.
This cycle will be repeated until reset or power is interrupted.

C.

Starts timing on trailing edge of start signal.
Output is turned on at the leading edge of the start signal.
Output is turned off when timed out.

D.

Starts timing on leading and trailing edge of start signal.
Output is turned on during timing, and off when timed out .
When timed out (from the trailing edge), the timer is ready for another start input.
