Unipi Extension xS11

Product description

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 both Unipi Neuron and Unipi Patron controllers, as well as PLCs from other vendors. 

Features

Inputs & outputs description

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. 

Communication interfaces

Extension modules communicate through the RS485 interface (Modbus protocol). The connection manual for extension modules can be found on this link.
