CT4S1P2 Counter/Timer — compact, reliable control for counting and timing tasks Why this model helps Compact panelmount size (W48 x H48 mm) saves space while providing clear control information on a 4digit display. Accepts either PNP or NPN sensor inputs for fast, straightforward integration with common proximity sensors and photoelectric detectors. Builtin prescale value setting lets you handle frequency signals or reduce resolution without extra hardware. Single preset simplifies automation: compare counts or elapsed time against one setpoint and actuate equipment automatically. SPDT relay output (1c) rated 250 VAC, 5 A provides a robust switching interface for valves, motors, solenoids, alarms, or PLC inputs. Key attributes Model: CT4S1P2 Function: Counter / Timer (combined functionality for counting pulses or timing events) Display: 4digit readout for clear numeric feedback Presets: 1 preset (single setpoint) Sensor input compatibility: PNP or NPN input types supported Prescale: Prescale value setting available to adjust counting resolution and handle frequency sources Output: Relay SPDT (single pole double throw, 1c), rated 250 VAC, 5 A Size: W48 x H48 mm panelcompatible footprint How it solves common problems Eliminates the need for separate counter and timer modules by combining both functions in one compact device. Supports both PNP and NPN sensors, avoiding compatibility issues and extra wiring adapters. Prescale setting prevents missed counts on fast signals and reduces wiring complexity by letting the device scale inputs internally. The relay output provides a dependable electromechanical contact suitable for a wide range of loads, reducing dependence on more complex solidstate outputs. Typical applications Production line part counting: count items on a conveyor and trigger a diverter or stop the line when the preset is reached. Process timing: measure and control cycle times in assembly, curing, or dwell operations where a single timing setpoint is required. Packaging and filling: monitor fill cycles or bottle counts and activate a reject or indexing mechanism when target counts are achieved. Installation and integration notes Designed for panelmounted installation with a standard W48 x H48 mm footprint for spaceefficient control panels. Works with standard PNP or NPN sensors; verify sensor wiring convention to match the CT4S1P2 input. Use the prescale setting to match signal frequency and desired counting resolution; ideal when inputs exceed direct counting capability. Reliable control for compact panels The CT4S1P2 delivers a straightforward, dependable solution when you need accurate counting or timing, sensor compatibility, and a reliable relay output in a small panel footprint. It is suited to production, packaging, machine control, and general automation tasks where one preset and clear numeric feedback are sufficient.
