Network relay
For load currents up to 16 A
Wiesemann & Theis is expanding its range of network-based 230 V remote switches to include two products with potential-free normally open and changeover contacts for load currents of up to 16 A.
The Web-IO 4.0 230V relay 1xNO, 1xCO switches one NO and one changeover contact up to 16 A each. The 'big brother' - the Web-IO 4.0 230V relay 4xNO, 4xCO - switches four NO contacts and four changeover contacts with up to 6 A per channel. The industrial-grade network relays, which can be installed on a 35 mm top-hat rail, can be queried and controlled via the network. In addition to the web interface and apps for iOS and Android, various communication protocols are available for data access: Modbus/TCP, OPC, MQTT and REST support integration into Industry 4.0 and SCADA applications. Integration into any other network products is possible via TCP, UDP, SNMP and FTP. According to the provider, the Web-IOs meet high security requirements. The individual network services can be activated independently of each other. For each operating mode, it is possible to specify which outputs may be switched. An overview page provides information about active services and assigned channels. Access to the web interface and the sending of emails can be TLS-encrypted on request.
