WebRelay-Dual is an Ethernet based, high performance, mini I/O module that has two electromechanical relays, two optically-isolated inputs, non-volatile memory for logging, and a real-time clock for full-calender scheduling, which can be used to turn on/off relays at preset times. It can be controlled via the Internet or a local intranet.
WebRelay-Dual has two optically isolated inputs that can be used to monitor the state of devices, control the local relays, control a remote relays somewhere else on the network, or send email (SMTP, no SSL) alerts. No software is required for setup or operation. Supports BASIC scripts for advanced configuration.
The ControlByWeb product line facilitates systems integration by offering Modbus/TCP functionality and simple XML control pages. You can also remotely access your Webrelays by using the CBW Mobile App.
This model has 2 relays (3A@28V) and 2 opto-input (4-12Vdc). The required power supply is 9-28Vdc. Model with PoE is mentioned below.
