PET-2228CI PoE I/O Module, 8-ch Analog Output with 2-port Ethernet Switch

The PET-2224CI CR provides four analog outputs that can each be set to 0 ~ 5 V, 0 ~ 10 V, 0 ~ 20 mA or 4 ~ 20 mA, with voltage or current mode selected in software. Every channel has a programmable power-on value and safe value, and the 4 ~ 20 mA channels include open wire detection.Networking is handled by a 2-port Ethernet switch with LAN bypass, which suits daisy-chain wiring. The unit can be powered over PoE (IEEE 802.3af, Class 2) or from a +10 ~ +48 VDC terminal block. Its I/O Pair Connection feature lets remote AI data be written to local AO channels in Pull mode via Modbus TCP.MQTT publisher and subscriber support, with automatic reconnection and a Keep-Alive interval, helps keep I/O status available to a broker. Isolation and EMS protection are provided for electrically noisy industrial environments.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-2228CIS is an Ethernet I/O module for engineers who need eight analogue outputs controlled over the network. Each channel can be configured individually for 0 ~ 5 V, 0 ~ 10 V, 0 ~ 20 mA or 4 ~ 20 mA operation, so one module can serve mixed voltage and current loads.Output integrity is supported by readback of the output values, over-value protection, short-circuit protection and open wire detection on the 4 ~ 20 mA channels. Programmable power-on and safe values define the state of the outputs at start-up and during communication faults, while dual watchdogs help the module recover from faults.The built-in 2-port switch with LAN bypass allows daisy-chain wiring, and the module can be powered from PoE or from a +10 ~ +48 VDC terminal block. I/O pair connection can write remote analogue input data to local outputs in Pull mode via Modbus TCP, and MQTT publish and subscribe features support integration with broker-based systems.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment
