Web-based relay output modules are flexible and easy-to-use solutions. They allow you to trigger a remote relay device from any location through a standard web browser like Microsoft Internet Explorer or Mozilla Firefox.
Web-based relay output devices feature a built-in web server for configuration, monitoring, and control. Modbus TCP communication over Ethernet provides easy integration with SCADA and other monitoring and control software through drivers.
-Ethernet-based data acquisition modules can communicate over the Modbus TCP protocol. The ET-7060, for example, has six power relay outputs and six Wet Contact (Sink, Source) digital input channels that support +10VDC to +50VDC voltage levels.
-Different users with passwords can be configured through the web HMI (Human Machine Interface). You can control access to the module through IP filters, restricting unauthorized IP addresses and allowing only hosts within a specific IP address range.
-The ET-7060 supports I/O pairing, allowing configuration through the web HMI so that the input on one module can trigger the output on another.
Some Ethernet-based data acquisition devices are powered over the Ethernet cable. They can be connected by an Ethernet cable to a Power over Ethernet (PoE) switch such as the NS-205PSE.
The PET-7060 can be powered over Ethernet or with 12–48 VDC auxiliary power. The NS-205PSE provides up to 15.4 watts of power per port. The PET-7060 has the same web HMI, Modbus TCP, and I/O features as the ET-7060.
Configurable Ethernet-based data acquisition controllers like the WISE-7160 can also be powered over Ethernet or with 12–48 VDC auxiliary power. They can be configured to implement up to 36 IF–THEN–ELSE IF type control logic conditions through a web page.
The WISE-7160 can be set to trigger a relay based on an input. It has 48 internal registers to hold temporary read/write data via Modbus TCP address. Up to 12 timers can be set up to provide timing and delay functions. The WISE-7160 can also be configured to send email messages based on specific conditions.
The WISE-7160 features the same Modbus TCP and I/O capabilities as the ET-7060 and PET-7060.
