PET-2224CI PoE I/O Module with 2-port Switch, 4-ch Analog Output

The PET-2228CI is an 8-channel analog output module for Ethernet-based control networks. Each channel can be configured individually for 0 ~ 5 V, 0 ~ 10 V, 4 ~ 20 mA or 0 ~ 20 mA output, with voltage or current selected in software. Programmable power-on and safe values define the output state at start-up and during communication faults, and open wire detection is available on the 4 ~ 20 mA channels.Power can be supplied over PoE (IEEE 802.3af, Class 3) or from a +10 ~ +48 VDC terminal block. A 2-port switch with LAN bypass allows daisy-chain wiring, and the module supports dual watchdog monitoring. I/O pair connection lets remote analog input data be written to local AO channels in Pull mode via Modbus TCP, which is useful where data is shared between remote units.The module can act as an MQTT publisher and subscriber, publishing I/O status as topics and receiving messages from subscribed topics. Automatic reconnection and a Keep-Alive interval help maintain the broker connection. Isolation is rated at 3000 VDC for I/O and between channels, and the built-in web server handles configuration.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

ET-2228CI CR is an Ethernet I/O module that provides eight differential analogue outputs, each individually configurable for voltage (0 ~ +5 VDC, 0 ~ +10 VDC) or current (0 ~ 20 mA, 4 ~ 20 mA) operation. It suits engineers who need to drive field actuators and valves from a networked controller while keeping channels electrically separated from one another and from the I/O side.The module includes a built-in web server for configuration and a 2-port 10/100 Base-Tx switch with LAN bypass, so units can be daisy-chained along a network line. Power-on and safe output values are programmable, and open wire detection is available on the 4 ~ 20 mA channels. I/O Pair Connection allows analogue input data from a remote module to be written to local outputs in Pull mode via Modbus TCP.For MQTT-based systems, the module can publish I/O status as topics and receive messages from subscribed topics, with reconnection and Keep-Alive mechanisms to maintain the broker link. Typical use cases include factory and machine automation, building automation, remote diagnosis and maintenance, and test equipment.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

ET-2224CI is a 4-channel analog output module for Ethernet-based control networks. Each channel can be set individually to 0 ~ 5 V, 0 ~ 10 V, 0 ~ 20 mA or 4 ~ 20 mA, so one module can serve a mix of voltage and current actuators. Configuration is carried out through the built-in web server, and the power-on and safe output values are programmable for each channel.The built-in 2-port 10/100 Base-Tx switch with LAN bypass allows devices to be daisy-chained along a line, reducing the cabling needed back to the switch. Open wire detection is provided for each 4 ~ 20 mA channel, and dual-watchdog support helps the module return to a defined state if communication is lost. I/O Pair Connection lets remote analog input data be written to local outputs via Modbus TCP.For connectivity, the module supports Modbus TCP and Modbus UDP, and it can act as an MQTT publisher and subscriber, with automatic reconnection and Keep-Alive handling. SNMP V2c is also supported. The metal casing and DIN-rail mounting suit control cabinet installations, with 3000 VDC I/O and channel-to-channel isolation for noisy industrial environments.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

The PET-2224CIS drives four analog outputs from an Ethernet-connected remote I/O node. Each channel can be set individually to 0 ~ 5 V, 0 ~ 10 V, 4 ~ 20 mA or 0 ~ 20 mA, so one module can serve a mix of voltage- and current-input actuators and valves.Output read-back and over-value protection help confirm what the module is actually driving. Power-on and safe values are programmable per channel, and open wire detection is available on the 4 ~ 20 mA outputs. The module is also PoE-powered and includes a 2-port switch with LAN bypass, which simplifies daisy-chain cabling in panels and machines.Communication is available through Modbus TCP/UDP, MQTT and SNMP V2c. The module can publish I/O status as MQTT topics, subscribe to command topics, and reconnect automatically after a broker disconnection. Its I/O Pair Connection feature can also write remote AI data to local AO channels in Pull mode.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment
