PET-7228 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

The PET-7028 CR is a PoE-powered Ethernet module that provides eight analogue outputs for driving actuators, valves and instruments from a networked I/O point. Each channel can be set by jumper to voltage or current, giving a choice of +0 ~ +5 VDC, ±5 VDC, +0 ~ +10 VDC, ±10 VDC, 0 ~ 20 mA and 4 ~ 20 mA ranges.Communication runs over a single 10/100 Base-TX RJ-45 port with Modbus TCP and Modbus UDP support. The module includes a built-in web server with Web HMI, access control by ID, password and IP filter, communication security, a dual watchdog and I/O pair connection. Power can come from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, and reverse polarity protection is fitted.Designed for DIN-rail installation in a 72 x 123 x 35 mm housing, the module offers 2500 VDC intra-module I/O isolation and ±4 kV EFT and ±4 kV contact ESD protection. It operates from -25 ~ +75 °C and is rated for 10 ~ 90% RH, non-condensing.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The PET-7224 CR is a PoE-powered Ethernet I/O module that combines four analogue outputs, five digital inputs and five digital outputs in one DIN-rail unit. Each analogue output can be set to voltage or current through its jumper, covering +/-5 V, +/-10 V, 0 ~ 20 mA and 4 ~ 20 mA ranges, so one module can suit a wide mix of actuators and valves.Communication is handled over Modbus TCP and Modbus UDP, with a built-in web server and web HMI for configuration and monitoring. A 2-port switch with LAN bypass allows units to be daisy-chained along a network, reducing the cabling needed for distributed I/O.Electrical protection includes 2500 VDC intra-module isolation and 4 kV ESD protection. Dual watchdogs, programmable power-on and safe values for outputs, and the device's I/O pair connection support dependable operation in automation and remote diagnosis tasks.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
