Data Acquisition
-DI/Counter: 8 Channels
-DO: 8 Channels
The WF-2255 is a dual bands 2.4/5 GHz Wi-Fi interface and 8-channel isolated digital input with 32-bit counters, 8-channel sink type isolated digital output module. With the popularity of 802.11 network infrastructure, the WF-2255 makes an easy way to incorporate wireless connectivity into monitoring and control systems. The WF-2255 also supports Modbus TCP protocol and the network encryption configuration, which makes perfect integration to SCADA software and offer easy and safe access for users from anytime and anywhere.
