Unipi Extension xS11 is an extension module communicating via the RS485 serial interface (Modbus RTU). The module is a simple and inexpensive method of extending your project by additional inputs & outputs. The xS11 combines a higher number of digital inputs and relay outputs, making it suitable for a wide range of applications. The module is designed for installation on a DIN rail and is compatible with Unipi controllers, as well as PLCs from other vendors.
Note: The product is a development successor to the Extension xS10, xS30, and xS40 modules.

Digital inputs (DI) are designed to read binary logic states represented by direct voltage levels. That makes them suitable for reading data from various binary sensors and devices such as switches (on/off), motion sensors (movement detected/not detected), liquid level sensors (full tank/empty tank), etc. All digital inputs also feature counter functionality by default.
Relay outputs (RO) are primarily used for switching two-state devices with higher current draw such as lightbulbs, thermoelectric valve drives, water heaters, pumps, etc.
Extension modules communicate through the RS485 interface (Modbus protocol). The connection manual for extension modules can be found on this link.
Along with standard inputs and outputs, the module also features other functions broadening its possible uses. For more information on these features, please visit our Knowledge Base.
