Hollysys LE - IO-Collect/Logic-Control - Stable Energy-saving Industrial PLC

The Hollysys LE series is a next-generation compact programmable logic controller family, available in both 24VDC and 100-240VAC powered CPU variants. Representative models such as LE5107 / LE5108 / LE5118 combine an on-board I/O mix (e.g., 14DI/10DO up to 24DI/16DO, with optional 2AI/2AO on select units) and deliver 0.1 µs bit-instruction execution using a 32-bit architecture.

Highlights include up to 8 high-speed counter channels (200 kHz, bidirectional up to 400 kHz) and up to 4-axis 100 kHz pulse outputs on transistor-output CPUs, plus removable terminal blocks, DIN-rail / panel mounting, and USB memory-card based bulk download with encryption for faster commissioning and IP protection.

Designed for standalone machines and small production lines, the LE series scales to up to 20 local I/O expansion modules—reaching roughly 492 digital I/O or 162 analog I/O—and supports multi-CPU data sharing plus optional Ethernet / GPRS / Profibus-DP links for remote monitoring.

Its motion portfolio covers PWM output, HOME homing, absolute/relative positioning, JOG, and interrupt-driven fast-event handling, making it a strong fit for packaging, textile, printing, plastics, food-processing, HVAC, and constant-pressure water-supply equipment. The AutoThink IDE shortens development with drag-and-drop function blocks, wizards (PID, recipes, comms configuration), online monitoring/offline simulation, and password-protected upload/download—delivering a compact, cost-effective, and maintainable control platform.
