The Autonics LE4S Digital Timer delivers versatile interval timing, high-contrast process visibility, and multi-mode relay switching engineered specifically for automated packaging machines, conveyor transfer tables, plastic injection auxiliary units, and industrial pumping panels.

High-Precision Timing Regulation with the Autonics LE4S Digital Timer

Designed to optimize machine-level sequencing, the Autonics LE4S Digital Timer provides programmable multi-operation timing within a compact 1/16 DIN (48 × 48 mm) enclosure. Featuring a high-visibility negative transmission LCD screen with bright backlight characters, the display presents real-time elapsed run time alongside programmed target setpoints with exceptional visual clarity from wide angles.

The unit incorporates comprehensive operational flexibility, allowing engineers to configure up to 10 distinct output timing modes—including ON-delay, Interval, Flicker, Star-Delta, and Twin Timer functions. With independent time-setting ranges spanning from fractions of a second up to 9,999 hours, the timer serves as a universal control standard, eliminating the need to stock multiple dedicated timing relays across machine assembly lines.

Technical Specifications

Industrial Applications and Process Integration

The Autonics LE4S Digital Timer is widely implemented across manufacturing equipment and automated control cabinets, including:

• Packaging heat-sealing bar dwell intervals, bag cutting pulses, and carton taper delays.
• Star-delta motor starter transition sequencing and conveyor index staging lines.
• Automated central lubrication dispensing systems and cyclic filter backwashing.
• Environmental chamber purge timing, curing oven exhaust cycles, and ultraviolet exposure units.

Frequently Asked Questions

What is the advantage of the Twin Timer mode on the Autonics LE4S Digital Timer?
The Twin Timer (TWN) mode enables independent configuration of ON time and OFF time durations. This allows technicians to create asymmetric cyclic flashing or continuous intermittent pump running and resting cycles without purchasing an additional secondary timing relay.

Can the timer accept both PNP and NPN field sensor triggers?
Yes. The input circuit is software-selectable between voltage input (PNP) and no-voltage contact/open-collector input (NPN), enabling direct interfacing with proximity sensors, limit switches, and PLC transistor outputs.

Which mounting socket is required for panel and DIN-rail installation?
The timer uses a standard 8-pin octal plug-in connection base, making it fully compatible with standard 8-pin DIN-rail screw sockets (such as the Autonics PG-08) for enclosure mounting or rear-clamping brackets for flush panel cutouts.
