1/4 DIN Counter and Timer/Counter for Industrial Automation
ATC Diversified Electronics offers the 653 Series Multi-Function Multi-Range Solid State Timer Counter for industrial applications requiring both programmable timing and electronic counting from one control. The 653 can function as a timer, counter, or electronic repeat-cycle timer, making it suitable for OEM machinery, packaging equipment, material handling, production systems, batching, process control, and machine-cycle monitoring.
In counter operation, the 653 provides three selectable count speeds up to 7,500 counts per second, count-input scaling, a cycle counter, programmable count values, and a 4-1/2 digit LCD that can display the count remaining or elapsed.
When used as a timer, five timing ranges cover values from 1 millisecond to 199 hours 59 minutes. The controller also provides six single-cycle and eight repeat-cycle timing modes, allowing the same device to support both counting and sophisticated timed machine sequences.
Why Choose the ATC 653 Timer Counter?
Timer and Counter in One Control: The 653 combines electronic counting and programmable timing, reducing the need for separate timer and counter devices in applications requiring both functions.
High-Speed Counting: Three selectable count speeds support counting applications up to 7,500 counts per second.
Count Input Scaling: Input scaling allows incoming count pulses to be adjusted to correspond with the quantity or process value being monitored.
Cycle Counter: The 653 can track the number of completed operating cycles in addition to performing its active timer or counter function.
Six Single-Cycle and Eight Repeat-Cycle Modes: Fourteen selectable timing modes provide flexibility for machinery and process applications requiring one-time or continuously repeating sequences.
Five Timing Ranges: Timing extends from 1 millisecond through 199 hours 59 minutes, supporting both short machine events and long-duration process timing.
Elapsed or Remaining Display: The 4-1/2 digit LCD can indicate either elapsed or remaining time or count according to the selected operating configuration.
Front-Keypad Programming: Time and count values are entered using the front-panel keypad, which also provides access to reset, immediate time/count out, inhibit, display direction, cycle-count display, and cycle-counter clearing functions.
Data Retention Options: Selected 653 models use EEPROM circuitry while others use lithium-battery memory to retain programmed values.
Electronic Counter Operation
In counter mode, the 653 industrial counter accepts electrical count inputs and compares the accumulated value with the programmed setting. Three selectable count speeds allow the controller to be adapted to different sensor, switch, and electronic pulse applications.
Counting can be performed using line-voltage signals or 12-48 VDC / 24 VAC inputs, depending on the selected wiring and jumper configuration.
Count-input scaling provides additional flexibility where the incoming pulse does not directly represent one displayed unit or where a machine process requires conversion between raw pulses and the desired count value.
Electronic Repeat-Cycle Timer Operation
The 653 can also function as an electronic repeat-cycle timer. It provides six single-cycle and eight repeat-cycle timing modes, for a total of 14 selectable timing functions.
Timing modes, timing range, and count speed are selected through an internal DIP-switch assembly. This allows one controller to be configured for different machine-control sequences without changing to another timer or counter family.
Timing from 1 Millisecond to Nearly 200 Hours
Five timing ranges provide an overall span from 1 millisecond to 199 hours 59 minutes. This broad range allows the 653 to support fast machine sequencing as well as extended industrial process timing.
The LCD can show either elapsed or remaining time, giving operators a clear indication of the current timing cycle.
Instantaneous and Programmable Relay Outputs
The 653 provides both an instantaneous relay output and a programmable relay output. The programmable output operates according to the selected timer or counter sequence.
This arrangement allows the controller to provide both an immediate control response and a second response based on the programmed timing or counting logic.
Programming, Inhibit and Cycle Monitoring
The 653 front keypad is used to enter the desired time or count value. Secondary functions include reset, immediate time/count out, time/count inhibit, changing the direction of the display, viewing the number of completed cycles, and clearing the cycle counter.
An external input can also determine whether the time-inhibit or count-input function responds to the application or removal of voltage, depending on the selected setup.
Memory Options for Retaining Programmed Settings
Selected 653 configurations use EEPROM data-retention circuitry, while other versions use a lithium battery. These memory options allow programmed values to be retained according to the selected model configuration.
Current EEPROM models include the 653-8-4000 and 653-8-4001, while 653-8-5000 and 653-8-5001 models use lithium-battery data retention.
653 Timer Counter Applications
The 653 can be used in packaging machinery, conveyors, material handling, production equipment, batching systems, food and beverage machinery, processing equipment, machine-cycle control, and other industrial automation applications where counting, timing, or repeating sequences must be controlled electronically.
ATC specifically identifies counting and batching as applications within material-handling systems, and the sealed faceplate can also be useful in industrial environments where the front of the control may be exposed to typical operating debris.
Find the Right 653 Timer Counter Configuration
Selecting the right industrial timer counter depends on whether timing or counting is required, maximum input frequency, input voltage, count-scaling requirements, desired timing mode, operating voltage, memory type, relay-output sequence, and the required installation configuration.
