‧Features::


Easy to Operate
Easy to operate: each digit has a reset switch, which is the same as a DIP Switch.
No complicated input design.

Multiple Operation Modes
Output operation, auto delay reset, instant reset, manual/auto reset.


Adjustable Time Output
0.1-999.9 sec., can be input from panel


Various Input
Users can input digits individually through aseries of additions/subtractions,or simply follow the directional instructions.


EEPROM Memory
Uses an IC to memorize counting values and setting values. Memory will 10 years without battery deterioration.


High-Speed Calculation
3,000 cps (max)


Timing Pause
Uses of GATE terminal can stop time count temporarily


Digital Filter
With connection signal less than 25cps,reducing flickers.


Complete Output Terminals
Provide two connections: N. O. and N. C.; and output terminals without connection.


Large Seven-section
Tube Model Display
Use different colors to separate setting values and counting values. Using a zero countdown, the digits are easy to identify.


Dustproof Structure
One-piece-formed model, membrane panel, without leakage and free from oil and dust.

Counting Input

Individual input (CP1: addition/CP2: subtraction)
CP1 (counting input), CP2 H (addition), CP2 L (subtraction)

Input
Non-connection input: ENCODER, application: proximity switches; L: 0-3V, H: 6-30V
Using DIP SW setting to setup H!÷L input (connection closed) or L!÷H (connection open)

Counting Speed
Without connection input: 3KHz (fastest), H/L: 170￡gS (min)
With connection input: 25KHz (fastest), H/L: 20ms (min)

Output

Connection output: from each of the connections (a, b) (AC250V, 3A)
Non-Connection output: NPN capacitor utput (DC30V, 0.5A)

Output Time


P1:Switches from N movement to P2 movement, and follows P2 mode.


P2:Operation or 0.1-999.9 sec. (setting by panel)





Output Mode


N, R, C (setting by DIP SW)


P1:Switches from N movement to P2 movement, and follows P2 mode.


P2:N,R,C, (setting by DIP SW)






Reset
External reset, panel button "RESET," an automatic reset by timing operation.


Counting Function override protection
When Counting is inprocess,users can'trevise settings and the terminal for receiving input digits will stop.

Counting Pause
When counting is in process, users can't revise settings, and the terminal for receiving input digits will stop.

Button Instructions

Use LED to indicate setting values and delay values
With LED indicators for P1,P2,and Time"Delay".

Output instructions

Use LED to indicate panel Time"Delay".
Use LED to indicate panel P1,P2,and Time"Delay".

Saving Memory
EEPROM can last 10 years. Setting values, counting values, and delay values can be memorized (max. 12V, 50mA)

Power
AC 110V/220V

Operating Temperature
-10°C~+50°C
