The Weintek IR-ETN40P is an industrial-grade Ethernet remote I/O module designed for high-performance automation environments.
As a modular I/O device, the IR-ETN40P provides standardized digital I/O channels (the "40P" configuration typically denotes a 40-point setup including various input and output channels). It connects to digital input devices such as pushbuttons, proximity switches, and photoelectric sensors, as well as digital output actuators like relays, solenoid valves, and indicator lights.
Features one Ethernet port for direct connection to PLCs, HMIs, SCADA systems, or industrial gateways. It fully supports Modbus TCP/IP for integration with Weintek CMT HMI series, cMT-CTRL PLCs, and third-party controllers from brands like Siemens, Mitsubishi, and Schneider Electric.
Designed for compact spaces, supporting standard 35mm DIN rail mounting. The secure screw-fastened terminals are built to handle frequent vibrations in demanding workshop settings.
Operates on a 24VDC industrial power supply (with tolerating voltage fluctuations of Ā±20%). It offers reverse polarity and overcurrent protection, and holds an IP20 rating ideal for dry control cabinet installations.
Enables structured distributed control, reducing wiring overhead by sending input signals from field sensors directly to higher-level controllers via Ethernet, and returning command signals to output actuators.
Configurable via EasyBuilder Pro or standard Modbus tools. Setup of IP addresses and mapping is straightforward, and hot-swappable module designs optimize maintenance routines.
Mix and match with other Weintek IR series modules (analog and special function modules) to dynamically expand your Ethernet control network from small machinery to massive production lines.
Withstands operating temperatures from -10Ā°C to 60Ā°C. Optimized electromagnetic compatibility (EMC) protects communication from shop floor electrical noise.
Single-Machine Equipment Control: Applied in injection molding, packaging, and printing machines to manage status signals (e.g., pressure and temperature) and output operations.
Distributed Production Lines: Used in automotive assembly and electronics fabrication, linking isolated assembly stations to central controllers over Ethernet.
Environmental and Room Monitoring: Integrates sensors monitoring temperature, humidity, and security/smoke alarms back to facility management portals.
Legacy Equipment Upgrades: Easily bridges non-networked traditional hardware to modern Ethernet infrastructures.
The IR-ETN40P serves as Weintek's core Ethernet I/O solution for small-to-medium project expansions as well as high-capacity distributed networks, bridging the physical field device layer to high-level system control.
Available Models: Weintek IR series IR-ETN40P / iR-ETN40R Ethernet I/O Module
