The Autonics CT6M-I4 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 features an indicator output. It operates on 100–240 VAC at 50/60 Hz with an external power supply option up to 12 VDC. Time operation runs on POWER ON START and SIGNAL ON START. 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 across multiple scales. The device includes IP65 front-panel protection, a counting range from -99,999 to 999,999 with a decimal point up to the fifth digit, and minimum input widths for RESET of 1 ms or 20 ms. Timer inputs INA, RESET, INHIBIT, BATCH, and RESET share the same 1 ms/20 ms option. Operating temperature is -10 to 55°C (storage -25 to 65°C) with 35–85% relative humidity (storage the same). This model is well suited for compact industrial counting, timing, and interval control.
