ET-7251 Ethernet I/O Module, 16-ch Wet Contact DI with 2-port Switch

The ET-7051 CR is an Ethernet remote I/O module that brings 16 wet contact digital inputs onto a Modbus network. Each channel can also be set up as a 32-bit counter, which makes the module suited to counting pulses from sensors, meters and switch contacts without a separate counting device.Isolation is provided between the Ethernet side, the I/O side and the power input, with 2500 VDC rated for I/O and 1500 VDC for Ethernet. Channels are not isolated from one another. The module is designed for installations where hazardous voltages may be present on the input side.The built-in web server and web HMI allow the module to be configured and monitored from a browser. Access is controlled through ID and password protection plus an IP filter, and the module offers a dual watchdog and I/O pair connection for supervised operation.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

PET-7051 CR is a PoE-powered Ethernet I/O module that monitors 16 wet contact digital inputs. Each input can also be configured as a 32-bit counter, which suits pulse counting and event logging on machines and building services.The module supports both Modbus TCP and Modbus UDP, and includes a built-in web server with web HMI for configuration and status viewing. Its I/O is isolated at 2500 VDC, and the inputs tolerate up to 70 VDC overvoltage. Channels are not isolated from each other, so the module suits applications where the input circuits share a common reference.Communication security features include ID, password and IP filter access control, plus a dual watchdog and programmable communication watchdog. The module is designed for DIN-rail mounting and operates from -25 ~ +75 °C.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The PET-7251 CR is a PoE Ethernet I/O module that brings 16 wet contact digital inputs onto a Modbus network. Each channel can also operate as a 32-bit counter, with a maximum count of 4,294,967,295 and an input frequency of 100 Hz, which suits pulse counting and status monitoring from field contacts.An integrated 2-port 10/100 Base-TX switch with LAN bypass allows the module to be daisy-chained along a line of devices. It can be powered either from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block. The built-in web server and Web HMI, together with ID, password and IP filter access control, support configuration and remote supervision.Optical isolation is rated at 2500 VDC for I/O, with transient overvoltage protection stated at 3750 Vrms. Note that there is no channel-to-channel isolation. The module is DIN-rail mounted and is specified for an operating range of -25 ~ +75 °C.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
