ALT Image showing three EQSP32 expansion modules displayed side by side on a light technical blueprint background, representing downloadable 3D CAD models for mechanical design and DIN-rail planning. The modules include the EQXPH01 pH meter expansion module, the EQXAI08 8-channel analog input expansion module, and the EQX2G quad-band GSM/GPRS cellular expansion module. Each module is housed in a compact DIN-rail enclosure with front-facing connectors and status indicators. The image highlights the availability of EQSP32 expansion module 3D models to support system integration, DIN-rail layout planning, enclosure design, and mechanical installation in industrial automation and IoT applications.

The modules are arranged in a row, illustrating the expandable architecture of the EQSP32 platform.

ALT EQSP32 Wireless IoT Controller demonstrating PCC (Pulse Capture Count) mode for super-high-speed pulse counting above 100 kHz in industrial automation. The image shows a stainless steel process pipe with a flow or pulse sensor connected to the EQSP32 Micro-PLC. The controller performs hardware-based pulse counting with selectable rising, falling, or toggle edge detection, up to four PCC channels active simultaneously, and frequency capture calculation using the EQTimer class. Ideal for flow metering, encoder feedback, and energy pulse monitoring in IIoT systems.

ALT The EQSP32 Library v1.0.x is here, bringing a major set of upgrades that make the EQSP32 Micro-PLC an even more powerful platform for automation. This release introduces long-awaited features including Ethernet connectivity (EQSP32CE) with automatic Wi-Fi/Ethernet switching and full support for OTA firmware updates. On the I/O side, the new library adds CIN (Current Input) 4–20 mA current loop support with built-in overcurrent protection, and a new PCC (Pulse Capture Counter) mode for precise measurement of pulse-based devices such as water flow meters, dosing pumps, and turbine sensors.
