Produktinformasjon "tWF-PD4SR2A Wi-Fi I/O Module, 4-ch Isolated DI and 2-ch AC SSR Output"
The tWF-PD4SR2A CR is a compact Wi-Fi remote I/O module that brings wireless connectivity to monitoring and control systems. It complies with IEEE 802.11 b/g/n and can operate in Access Point (limited AP) or Station (STA) mode, so it can be added to existing 802.11 network infrastructure. Modbus TCP support and network encryption options (Open, WEP, WPA2) allow it to connect to SCADA software and HMI Modbus applications.
The module provides four photo-isolated dry contact digital inputs, each with a 32-bit counter, and two AC solid state relay outputs rated AC 240 V/1.5 A. Its 9 to 48 VDC supply input includes reverse polarity protection. Configuration is supported through a PC utility, an Android app or a web browser.
