ET-7261 Ethernet I/O Module with 2-port Switch, 11-ch Power Relay

The PET-7261 CR is a PoE Ethernet I/O module that switches 11 form A (SPST N.O.) power relays over Modbus TCP or Modbus UDP. Each relay is rated at 5 A at 250 VAC or 24 VDC for resistive loads, so the module suits switching duties in building, factory and machine automation without an extra interface layer.Relay outputs are optically isolated with 3000 VDC of transient overvoltage protection. Channels are not isolated from each other, so the module is best suited where the relay channels share a common reference. The power-on value and the safe value of each relay are programmable, which lets you define a known output state at start-up and on communication loss. The module is intended for use where hazardous voltages are present.A built-in 2-port 10/100 Base-TX switch with LAN bypass supports daisy-chain wiring, and the module can be powered either from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block. It is configured through its built-in web server and carries CE, UKCA, FCC, RoHS and WEEE certifications.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

ET-7260 CR is a DIN-rail Ethernet I/O module that combines six wet contact digital inputs with six form A power relays. Each input can be set up as a 32-bit counter, which suits pulse counting and status monitoring on distributed machines and panels.The built-in 2-port 10/100 Base-TX switch, with LAN bypass, allows modules to be daisy-chained along a network line. Communication is via Modbus TCP or Modbus UDP, and a built-in web server and web HMI support configuration and monitoring. Dual watchdogs and programmable power-on and safe values for the relays help the module respond predictably to faults.Isolation is rated at 1500 VDC for Ethernet and 3000 VDC for I/O, but the input channels are not isolated from each other. When switching inductive loads, fit a flyback diode for DC loads or a metal oxide varistor for AC loads to protect the relay contacts.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The ET-7260A CR is an Ethernet I/O module for remote monitoring and switching in distributed control networks. Six digital input/counter channels and six Form A power relay outputs are built in, so a single unit can read field contacts and switch loads without an extra I/O stage.Each module runs a built-in web server with a web HMI for setup, and it supports both Modbus TCP and Modbus UDP. This allows it to be integrated with HMI, SCADA, PLC and other industrial control software. Access control uses ID, password and IP filtering, and communication security is included as a listed feature.The two RJ-45 ports form an Ethernet switch with LAN bypass, so units can be daisy-chained along a line without a separate switch. Dual watchdogs, I/O pair connection and programmable power-on and safe values for the relays support robust operation. The module mounts on DIN-rail and accepts +12 ~ +48 VDC.HmmApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The ET-7267 CR switches loads through eight form A (SPST N.O.) power relays, with each channel rated at 5 A @ 250 VAC/24 VDC for resistive loads. Relay operate and release times are 10 ms and 5 ms maximum, and the module is configured over Ethernet with Modbus TCP or Modbus UDP.A built-in 2-port Ethernet switch with LAN bypass allows the module to be daisy-chained along a network, which simplifies cabling in distributed installations. The built-in web server and Web HMI provide browser-based access, and access control uses ID, password and IP filtering.The power-on value and safe value of each relay are programmable, and I/O is optically isolated to 3000 VDC. Because there is no channel-to-channel isolation, the module suits applications where hazardous voltages are present, provided the wiring is planned accordingly. Dual watchdogs cover both the module and communication.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
