ET-7253 Ethernet I/O Module with 2-port Switch, 16-ch Digital Input

The ET-7053 is an Ethernet remote I/O module that brings 16 dry contact digital inputs onto a Modbus network. Every channel can be used as a 32-bit counter, which suits pulse counting and event monitoring where input states must be reported to a host over Ethernet.Electrical isolation is provided on the input side, with 1500 VDC on the Ethernet interface and 2500 VDC on the I/O. The inputs are not isolated from one another, so channels share a common reference. The module is suitable for installations where hazardous voltages may be present, and its EFT and ESD immunity ratings are stated for use in industrial environments.The built-in web server and Web HMI, dual watchdog, I/O pair connection and access control with ID, password and IP filtering make the ET-7053 straightforward to supervise and secure on a plant network. It mounts on a DIN rail and operates from a +10 ~ +30 VDC supply over a wide temperature range.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

PET-7053 CR is a PoE Ethernet I/O module that brings 16 dry contact digital inputs onto a Modbus network. Every channel can also be configured as a 32-bit counter, making it suited to pulse counting and status monitoring tasks where a PLC or SCADA system needs remote visibility of field contacts.The module can be powered over Ethernet to IEEE 802.3af or from a +12 ~ +48 VDC terminal block, and it includes a built-in web server with web HMI for configuration and monitoring. Dual watchdogs (module and communication, programmable) help the module recover from faults. Access is protected by ID, password and IP filter.Optical isolation is provided between I/O and the system at 2500 VDC, with transient overvoltage protection rated at 3750 Vrms. Channels are not isolated from each other, so the module should be considered for applications where the inputs share a common reference. Its voltage rating allows use where hazardous voltages are present.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

PET-7253 CR is a PoE Ethernet remote I/O module that brings 16 dry contact digital inputs onto a Modbus network. Every input can also run as a 32-bit counter, which suits pulse counting and event tallying on machines and building systems.The built-in 2-port switch with LAN bypass lets you daisy-chain modules along a cable run without a separate switch at each point. Power can come from PoE (IEEE 802.3af, Class 1) or from a +12 to +48 VDC terminal block. Optical isolation gives 3750 Vrms transient overvoltage protection, although the channels are not isolated from each other.An embedded web server and web HMI allow configuration and monitoring from a browser, with access control by ID, password and IP filter. The dual watchdog and I/O pair connection support fault handling in unattended installations.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
