Industrial control boards, STM32 embedded controllers, modular I/O hardware, and complete PLC systems designed for demanding automation, OEM, and engineering environments.
EA Control Tech designs practical industrial control and embedded hardware for automation, prototyping, and system integration applications — from individual I/O boards to complete modular PLC systems.
Our products are engineered to integrate reliably into demanding environments — from factory floors to OEM equipment — with a focus on well-documented, modular designs that engineers can trust and customize.
Every board and system ships with thorough documentation, connector pinouts, and wiring guidelines, making integration straightforward for both embedded and industrial engineers.
Industrial STM32F407 controller with 24VDC input, RS485, CAN, SPI, I²C, RTC, Flash, and microSD. Designed for embedded automation systems requiring robust, well-connected processing.
16-channel digital input module based on MCP23017. Designed for reliable input monitoring in industrial and embedded applications over a simple I²C interface.
16-channel I²C relay output module based on the MCP23017. Compact, daisy-chainable design for controlling multiple relay loads from a single I²C bus.
8-channel I²C relay output module based on the MCP23008. A compact solution for applications needing fewer channels with the same reliable I²C interface.
4-channel AD74412R analog I/O with software-configurable modes: 0–10V / 0–11V voltage, 0–25mA / 4–20mA current loop, and 2-wire PT100/PT1000 RTD temperature measurement.
Flexible industrial PLC platform built from stackable 24VDC modules. Combine the STM32F407 CPU with analog I/O, opto-isolated digital inputs, and relay outputs in any supported configuration. Up to 128 DI, 128 DO, and 4 analog channels in a single system.
