Unipi Extension xS53

Product description

Unipi Extension xS53 is an extension module communicating via the RS-485 serial interface (Modbus RTU). The module is a simple and inexpensive method of extending your project by additional inputs & outputs. The xS53 features a set of analog inputs, but also digital inputs and outputs. This makes it suitable for implementation in more complex projects involving the measurement of analog components. The module is designed for installation on a DIN rail and is compatible with Unipi controllers, as well as PLCs from other vendors.

Basic 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.

Analog inputs (AI) are designed to measure 0-10 V⎓ voltage and 0-20 mA current, which makes them suitable for collecting data from analog sensors.

Communication interfaces

Extension modules communicate through the RS-485 interface (Modbus protocol). Instructions for connection and commissioning, including a description of SW and HW configuration of communication parameters, can be found on this link.
