Autonics CT4S-1P2 - Digital Counter

The Autonics CT4S-1P2 is a compact 4-digit 7-segment LED display/controller designed for precise counting and timing. It supports counter functions (count up, count down, count up/down) and timer functions (count up, count down), uses a terminal block, and features a 1-stage preset output with a SPDT relay and an NPN open-collector output. It operates from 24 VAC at 50/60 Hz or 24–48 VDC, with an external power supply option up to 12 VDC. Signal inputs accept voltage input (PNP) or no-voltage input (NPN). The maximum counting speed is configurable up to 10k cps, with a minimum input width of 1 ms or 20 ms. Memory protection is about 10 years. Setting ranges cover 0.001 s to 9,999 s and extend to longer scales, while the front panel carries IP65 protection. The counting range is -999 to 9,999 with a decimal point up to the third digit, and the minimum widths for RESET and INA/INH/RESET inputs are 1 ms or 20 ms. Operating temperatures range from -10 to 55°C (storage -25 to 65°C) with 35–85% RH humidity (storage the same). This makes the CT4S-1P2 well suited for compact industrial counting, timing, and interval control.
