Its I/O pair connection function links local DO channels to DI channels on a remote module over Ethernet, with remote DI data written to local outputs in Pull mode via Modbus TCP. Dual-watchdog support, a built-in web server and password and IP filter access control add to its configuration and operational options.For electrically demanding sites, the ET-2242 CR provides 3000 VDC I/O isolation and EMS (EFT/ESD/Surge) protection.

The ET-7060 CR combines six wet contact digital inputs with six form A power relays in a single Ethernet-connected DIN-rail module. Each input can also operate as a 32-bit counter, which suits pulse counting and status monitoring in automation and remote supervision tasks. Relay power-on and safe values are programmable, so outputs can be set to a defined state when the module starts or communication is lost.Communication is handled over a 10/100 Base-TX RJ-45 port using Modbus TCP or Modbus UDP. A built-in web server and web HMI allow configuration and monitoring through a browser, while dual watchdogs (module and communication, both programmable) help maintain system reliability. Access can be restricted with ID, password and IP filter controls.Isolation is rated at 3000 VDC for the I/O and 1500 VDC for Ethernet, with no channel-to-channel isolation. When switching inductive loads, fit a flyback diode for DC loads or a metal oxide varistor for AC loads to protect the relay contacts and extend relay life.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
