The Autonics CT6Y-2P4 is a 6-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 provides output options including SIGNAL ON DELAY, POWER ON DELAY, FLICKER, INTERVAL, SIGNAL OFF DELAY, ON-OFF DELAY, and INTEGRATION TIME. It operates on 100–240 VAC at 50/60 Hz, with an external power supply option up to 12 VDC. Signal inputs can be voltage input (PNP) or no-voltage input (NPN). The maximum counting speed is configurable up to 10k cps, with a minimum input width selectable as 1 ms or 20 ms. Memory protection is about 10 years. Setting ranges span from 0.001 s to 9999 h across multiple scales, and the device features a 2-stage preset output with SPST and SPDT relays and an NPN open-collector output. The front panel is IP65 protected, and the counting range is -99,999 to 999,999 with a decimal point up to the fifth digit. Reset input width is selectable 1 ms or 20 ms, and INA/INH/RESET inputs have a 1 ms or 20 ms minimum width for timer operation. Operating temperature is -10 to 55°C (storage -25 to 65°C) with 35–85% RH humidity (storage the same). This makes the CT6Y-2P4 well suited for industrial counting, timing, and interval control with enhanced output options.
