Introduction:

The ET-7250A and PET-7250A provide full networking capabilities, and a variety of I/O functions, together with a web-based user interface server for easy configuration. Both modules can be remotely controlled using the Modbus TCP/UDP protocol via an Ethernet network. This helps the ET-7250A and PET-7250A to be well integrated with HMI, SCADA, PLC and other industrial control software systems.
 

I/O Pair Connection

The ET-7250A and PET-7250A provide 6 sink-type digital output channels and 12 wet/dry contact digital input channels, each of which is able to be used as a 32-bit counter.
The DI channels and DO channels can be paired over the Ethernet. That is to say, when the remote DI channels get the ON signal, the corresponding local DO will be turned on; while the DI channels get OFF, the corresponding local DO channels will also become OFF, it does not require another controller to implement the function.

 

Daisy-Chain Ethernet Cabling

The ET-7250A and PET-7250A include two built-in Ethernet switch ports, which are helpful to reduce implementation costs. No additional switch to be installed or maintained when you need to daisy chain the devices or to extend the network.


 

Power over Ethernet (PoE)

The PET-7250A supports IEEE 802.3af Power-Over-Ethernet (Class 1) specifications. By connecting to network devices that support the IEEE 802.3af PoE standard, power can be supplied via a copper Ethernet cable.
