The SX300 Counter is a microprocessor based, 6 digit counter housed in a standard DIN style case (68 mm square cutout). The small case and front bezel require minimal panel space, yet provides large, easy to read 36 inch LED display.
The SX300 Counter is designed for a single direction count input from a solid state sensor or switch. The DC input versions will count up to 2500 counts per second. The AC input version will count up to 2500 counts per minute. Two individually programmable relays provide a wide variety of output combinations to suit most applications.

MAX Series, count 6 Digital Preset Counters
Display: 6 Digit LED Display, .36" high
Decimal Point: User programmable, can be positioned between any of the 6 digits
Main Counter:
Setting Accuracy: ±0.05% of setting or 50 ms, whichever is larger
Repeat Accuracy: ±0.001% of setting or 35 ms, whichever is larger
Programmed Pulse: 0.01 to 99.99 seconds
Reset Time: 15 ms
Power on Response: 200 ms max.
Control Outputs:
Output 1 Modes: ON-Delay, Interval, ONTimed Pulse Output, Timed Pulse and Repeat, Repeat Cycle, ON or OFF Time Cycle First
ON-Delay: Output 1 is energized at the end of the timing cycle
Interval: Output 1 is energized during the timing cycle
ONTimed Pulse Output: Output 1 is energized for a programmable pulse time up to 99.99 seconds at the end of the timing cycle.
Timed Pulse and Repeat: Output 1 is energized for a programmable pulse time up to 99.99 seconds at the end of the timing cycle with the time cycle automatically repeating.
Repeat Cycle, ON or OFF Time Cycle First: Output 1 is energized and de-energized in repeating operation with either the ON or OFF time period first. The time periods are equal length. Unequal length time intervals can be obtained using the Early Trip prewarn output.
Output 2 Modes: Output 2 can be programmed to operate in parallel with Output 1, providing DPDT relay operation form the two SPDT relays, or it can be programmed as an Early Trip prewarn output that is energized at a predetermined time before the end of the cycle. An example of Early Trip prewarn operation with the ON Delay mode for Output 1 is shown here for reference.
