ET-2242U-32 Ethernet I/O Module with 32-ch DO (Sink/Source)

The ICP DAS ET-2242U-32 is a 32-channel digital output (Sink/Source-type) module. Each channel provides photocoupler isolation and short circuit protection, capable of driving a 300 mA load. The module includes a built-in 2-port Ethernet switch, facilitating a daisy-chain topology. This feature offers flexibility in device configuration, simplifies installation, and reduces infrastructure costs. Additionally, the module provides EMS (EFT/ESD/Surge) protection and 3000 VDC I/O isolation to enhance noise protection capabilities in industrial environments. It also offers configurable DO power-on value and safe value settings.

Moreover, the module supports I/O Pair-Connection functionality, allowing the establishment of DI-to-DO pairing connections with the remote module via Ethernet. Once configured, remote DI data can be written to local DO channels in Pull mode via Modbus TCP.

The ET-2242U-32 supports the MQTT protocol, serving as a publisher and subscriber of messages. When connected to an MQTT Broker Server, it can publish real-time statuses of I/O in the form of topics and receive messages from subscribed topics. If a disconnection occurs between the module and the broker during communication, its mechanism for reconnecting can automatically restore the connection. Additionally, its Keep-Alive Interval mechanism ensures a continuous connection with the broker.

The ET-2242U-32 supports the SNMP V2c specification, enabling it to transmit both module and I/O information to SNMP network management devices or software (SNMP Network Management Software). This allows administrators to monitor module status in real-time. Additionally, if the Trap function is enabled, the module can proactively send messages to administrators when there are changes in I/O statuses or during restarts, keeping them informed of channel statuses at all times.

It is equipped with removable terminal block connector for easy and robust wiring in industrial situations, and features a powerful 32-bit ARM MCU to handle efficient network trafficking.
