The Autonics CT6M-1P4 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 1-stage preset output with an SPDT relay and a dual NPN open-collector output. It operates from 100–240 VAC at 50/60 Hz, with an external power 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 span from 0.001 s to 9,999 s and extend across multiple scales, and the front panel is IP65 protected. The counting range is -99,999 to 999,999 with a decimal point up to the fifth digit. Reset inputs have a selectable 1 ms or 20 ms width, while timer inputs INA, RESET, INHIBIT, BATCH, and RESET share the same 1 ms/20 ms option. Operating temperature runs from -10 to 55°C (storage -25 to 65°C) and humidity from 35 to 85% RH (storage the same). This model is well suited for compact industrial counting, timing, and interval control.
