ET-2228

ET-2228 is an 8-channel analog output module. The module provides a variety of programmable output ranges, including 0 ~ 5 V, +/-5 V, 0 ~ 10 V, +/-10 V, 4 ~ 20 mA, and 0 ~ 20 mA. It offers configurable AO power-on value and safe value settings, as well as open wire detection for each 4 ~ 20 mA output channel. 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.

ET-2228 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.

ET-2228 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.
