    The WF-2026 is a multifunction module with Wi-Fi interface that includes 5 analog input channels, 2 analog output channels, 2 digital input channels and 3 digital output channels. It provides a programmable input range on all analog input (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA or 0 ~ +20 mA) and output range on all analog output (12-bit at +/-5 V, +/-10 V, 0 ~ +20 mA or +4 ~ +20 mA). Each analog input and output channel can be configured for an individual range and provides a high overvoltage protection of 240 Vrms. Analog Input and output can be jumper selectable as either voltage or current.

    With the popularity of 802.11 network infrastructure, the WF-2026 makes an easy way to incorporate wireless connectivity into monitoring and control systems. The WF-2026 also supports Modbus/TCP and UDP protocols and the network encryption configuration, which makes perfect integration to SCADA software and offer easy and safe access for users from anytime and anywhere.
