The Autonics CT6Y-1P4 is a 6-digit 7-segment LED display/controller with display method on a 6-digit 7-segment format. It supports counter operations (count up, count down, count up/down) and timer operations (count up, count down), uses a terminal block, and offers output options including SIGNAL ON DELAY, POWER ON DELAY, FLICKER, INTERVAL, SIGNAL OFF DELAY, ON-OFF DELAY, and INTEGRATION TIME. It operates on 100-240VAC at 50/60 Hz, with an optional external power supply up to 12VDC. 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 of 1 ms or 20 ms. Memory protection is rated for about 10 years. The setting ranges cover from 0.001 s to 9999 h across multiple scales, and the device provides a 1-stage preset control output via SPDT relay and an NPN open-collector output. Its front panel is IP65 protected, and the counting range spans from -99,999 to 999,999 with a decimal point up to the fifth digit. Reset and INA/INH/RESET inputs have selectable 1 ms or 20 ms widths. Operating temperature ranges from -10 to 55°C (storage -25 to 65°C) with 35 to 85% RH humidity (same range for storage). This makes it suitable for precise counting, timing, and interval control in industrial settings.
