The Autonics CT6M-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 a 2-stage preset output with SPST and SPDT relays and a multi‑output NPN stage. 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 cover from 0.001 s to 9,999 s across multiple scales, and the device features IP65 front-panel protection. The counting range runs from -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 timer inputs INA, RESET, INHIBIT, BATCH, and RESET share the same 1 ms/20 ms option. Ambient temperature ranges from -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.
