Devices / Slaves

On a pair of Modbus wires, slaves can be addressed from 1 to 247. Each slave replies to Modbus Function Codes from the Master. Most slaves can measure data or interact with the environment, which is stored in registers. You can read/write registers with Function Codes.

Temperature and humidity sensor
This is a high precision temperature and humidity sensor module. It has a high precision probe that guarantees the products with excellent measurement performance. Thanks to this, it is ideal for real-time monitoring of multiple site environment.

Digital counter
This is an electronic unit with four digital counter imputs. It has a Modbus RTU communication interface to provide a simple way for integrating digital signals to supervisory system. The input signals are isolated from the power thus protecting the electrical instruments by eliminating ground loop effects.
