Autonics CT4S-1P4 Counter Timer Relay Module

Autonics CT4S-1P4 is a compact 1/16‑DIN, 4‑digit digital counter/timer that combines pulse counting and time‑based control in a single module. It operates from 100–240 VAC and provides both a SPDT relay output and an NPN open‑collector output, enabling immediate actuation of a load or direct PLC input without external interfaces. In counter mode, CT4S-1P4 supports multiple input configurations (9 input modes) and a broad set of output options (11 modes) to accommodate different counting schemes, while in timer mode it offers 13 distinct output behaviors for on‑delay, off‑delay, interval, and related timing sequences. The unit is designed for 1‑stage preset control and mounts in a standard 1/16‑DIN panel with screw terminals, measuring about 48 × 48 mm face area to fit compact control panels. This combination of a four‑digit LED readout, dual outputs, and flexible counter/timer functionality makes the CT4S‑1P4 well suited for discrete counting, event timing, and process control tasks on small automation projects or on larger production lines where a compact, locally configurable timer/counter is beneficial.
