PET-7028 PoE Ethernet I/O Module, 8-ch Analog Output

The ET-7028 CR is an Ethernet I/O module that provides eight analogue output channels for controlling field devices from a network. It suits engineers who need networked analogue control in building, factory and machine automation.Each channel can be set to a voltage range (+0 ~ +5 VDC, ±5 VDC, +0 ~ +10 VDC or ±10 VDC) or a current range (0 ~ 20 mA or 4 ~ 20 mA). The output type is chosen per channel by jumper position, and channels can be configured individually. Output resolution is 12-bit with an accuracy of ±0.1% of FSR, and open wire detection is available for 4 ~ 20 mA use. Power-on and safe values are programmable.Communication uses one RJ-45 10/100 Base-TX port with Modbus TCP and Modbus UDP. A built-in web server and web HMI, ID, password and IP filter access control, and programmable module and communication watchdogs support secure and supervised operation. The module is powered from +10 ~ +30 VDC with reverse polarity protection and is designed for DIN-rail mounting over -25 ~ +75 °C.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The ET-7228 provides eight analogue output channels for engineers who need Ethernet-based control of analogue field devices. Each channel can be set to voltage (+0 ~ +5 VDC, ±5 VDC, +0 ~ +10 VDC, ±10 VDC) or current (0 ~ 20 mA, 4 ~ 20 mA) using the jumper for that channel, so one module can cover mixed field devices.Modbus TCP and Modbus UDP are supported, and the built-in web server and Web HMI provide browser-based access to the module. The two RJ-45 switch ports with LAN bypass allow daisy-chain topologies, and the power-on and safe values of each output are programmable.Isolation is rated at 1500 VDC for Ethernet and 2500 VDC for I/O. The module runs from +12 ~ +48 VDC with reverse polarity protection, and is designed for DIN-rail mounting over an operating range of -25 ~ +75 °C.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

PET-7228 is an Ethernet I/O module for distributed analogue control. Its eight outputs can be set to voltage or current on a per-channel basis using jumpers, which lets one module serve a mixed set of actuators and valves without changing hardware.Each output supports +0 ~ +5 VDC, ±5 VDC, +0 ~ +10 VDC, ±10 VDC, 0 ~ 20 mA and 4 ~ 20 mA ranges. Outputs can be given individual configurations, and power-on and safe values are programmable so the process can fall back to a defined state. Modbus TCP and Modbus UDP communication is supported, and the built-in web server provides a web HMI.The integrated 2-port 10/100 Base-TX switch with LAN bypass allows the module to be daisy-chained along a network line. It can be powered over PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, and it is designed for DIN-rail installation.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
