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

The PET-2228 CR provides eight analog output channels for control and actuation tasks on Ethernet networks. Each channel can be set to one of several voltage ranges (0 ~ +5 VDC, ±5 VDC, 0 ~ +10 VDC, ±10 VDC) or current ranges (0 ~ 20 mA, 4 ~ 20 mA), with 12-bit resolution and an accuracy of ±0.1% of FSR. Power-on and safe output values are programmable, and open wire detection is available on the 4 ~ 20 mA channels.The module is designed for simple, low-cost installation. A built-in 2-port 10/100 Base-Tx switch with LAN bypass supports daisy-chain wiring, and the unit can be powered over PoE (IEEE 802.3af, Class 3) or from a +10 ~ +48 VDC terminal block. Dual watchdog monitoring (module and communication) and I/O pair connection (push and pull) help maintain predictable operation.Communication options include Modbus TCP and Modbus UDP, plus MQTT in which the module acts as a publisher and subscriber, and SNMP V2c with trap support for reporting channel status changes and restarts. A built-in web server handles configuration, and access is protected by password and IP filtering. The metal housing is rated for DIN-rail or wall mounting, with an operating range of -25 ~ +75 °C.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

The ET-2228 CR provides eight analogue output channels for driving voltage or current signals from an Ethernet network. Each channel can be configured for 0 ~ 5 V, ±5 V, 0 ~ 10 V, ±10 V, 4 ~ 20 mA or 0 ~ 20 mA, with 12-bit resolution and an accuracy of ±0.1% of FSR.A built-in 2-port 10/100 Base-Tx switch with LAN bypass allows the module to be wired in a daisy chain, which reduces the need for separate switches. Configuration is handled through a built-in web server, and the module supports Modbus TCP and Modbus UDP, MQTT publish and subscribe, and SNMP V2c with trap reporting.For reliable operation in industrial environments, the module offers 3000 VDC I/O isolation and EMS protection against EFT, ESD and surge. Power-on and safe output values are programmable, open wire detection is available on the 4 ~ 20 mA outputs, and dual watchdog functions are supported.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

The ET-2224 is a remote Ethernet I/O module that drives four analog outputs, selectable as voltage or current. Engineers can choose between 0 ~ +5 VDC, ±5 VDC, 0 ~ +10 VDC, ±10 VDC, 0 ~ 20 mA and 4 ~ 20 mA on each channel, with configurable power-on and safe values, and open wire detection on the 4 ~ 20 mA outputs.A built-in 2-port switch with LAN bypass allows modules to be daisy-chained along the network, which reduces cabling and switch hardware. The module reports I/O status over Modbus TCP/UDP, and can act as an MQTT publisher and subscriber or send SNMP V2c information and traps to network management software.The ET-2224 CR is the RoHS-compliant ordering variant. It offers 3000 VDC I/O isolation and EMS protection against EFT, ESD and surge, and it is configured through a built-in web server with password and IP filter access control.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

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
