The Autonics CT6Y-2P4T is a six‑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 2‑stage preset output with SPST relays and an SPDT option, plus RS485 communication for integrated control. It operates on 100–240 VAC at 50/60 Hz 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 extend from 0.001 s to 9.999 s across multiple scales, and the device carries IP65 front‑panel protection. The counting range runs from -99,999 to 999,999 with the decimal point up to the fifth digit, and the minimum widths for RESET and timer inputs INA, INH, RESET are selectable 1 ms or 20 ms. Operating temperature is -10 to 55°C (storage -25 to 65°C) with 35–85% RH humidity (storage the same). This model is well suited for compact industrial counting, timing, and interval control with robust communication capabilities.
