ET-7255 Ethernet I/O Module, 8-ch DI, 8-ch DO, 2-port Switch

PET-7255 CR is a PoE Ethernet I/O module that combines eight dry/wet contact digital inputs with eight source-type digital outputs. Each input can be configured as a 32-bit counter, and each output channel can drive up to 650 mA per channel at 25°C, making the module suitable for direct switching and counting tasks on a network-attached I/O node.A built-in 2-port 10/100 Base-TX switch with LAN bypass allows units to be daisy-chained along a cable run, reducing the switching hardware needed at each point. The module offers a built-in web server with Web HMI, Modbus TCP and Modbus UDP support, access control by ID, password and IP filter, and dual watchdog protection.Optical isolation of 2500 VDC is provided between I/O and the system, although channels are not isolated from one another. The power-on and safe values of the digital outputs are programmable, so outputs can be set to a defined state at start-up or when communication is lost.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The ET-7250A is an Ethernet I/O module from the ET-7000/ET-7200 series that brings 12 digital inputs and 6 digital outputs onto a Modbus TCP/UDP network. Its built-in web server and Web HMI allow the I/O to be monitored and controlled from a browser, and the module can be read or driven by HMI, SCADA and PLC software over Ethernet.Each digital input accepts either dry or wet contact signals and can be configured as a 32-bit counter, with a maximum count of 4,294,967,295 and a frequency of 100 Hz. The six outputs are isolated open-collector, sink-type channels rated for 500 mA per channel, with programmable power-on and safe values.Two RJ-45 switch ports with LAN bypass allow the module to be daisy-chained along the Ethernet line without an external switch. Isolation is rated at 1500 VDC on Ethernet and 2500 VDC on I/O. The unit is powered from +12 ~ +48 VDC and is designed for DIN-rail mounting with an operating range of -25 ~ +75 °C.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The ET-7251 is an Ethernet remote I/O module for collecting signals from 16 wet contact digital inputs and passing the data to a host over Modbus TCP or Modbus UDP. Each input can also be configured as a 32-bit counter, which suits pulse counting and event logging on machines and building services.Built-in switch ports allow modules to be daisy-chained along a network line, reducing cabling between cabinets. The module provides a built-in web server with a web HMI for configuration and monitoring, and access control based on ID, password and IP filtering. Watchdog functions cover both the module and the communication link.Isolation is provided between the Ethernet and I/O sides, but the inputs are not isolated from one another, so channels should share a common reference. The unit is DIN-rail mounted and is rated for operation from -25 to +75 °C.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The ET-7252 is a DIN-rail Ethernet I/O module that brings eight wet-contact digital inputs and eight source-type digital outputs onto a Modbus network. Each input can also be used as a 32-bit counter, which suits pulse counting and event logging without a separate counter module.Two integrated RJ-45 switch ports with LAN bypass allow the module to be daisy-chained along a line of devices, reducing the cabling needed for distributed I/O. A built-in web server and Web HMI are provided, and access is controlled by ID, password and IP filter.Optical isolation rated at 2500 VDC on the I/O side and 1500 VDC on the Ethernet side helps the module suit applications where hazardous voltages may be present. Digital output power-on and safe values are programmable, so each output can be given a defined state.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
