S4AI, RS-485 MODBUS Module with 4 Analogue Inputs

The S4AI module from LUMEL is designed to measure standard signals (voltage, current) or readings from resistance or thermocouple temperature sensors, etc. and to provide the measured values in a digital form via the MODBUS protocol.
Input signals are divided into two groups of two inputs which are insulated from each other.
RS485 interface and USB are galvanically isolated from the input, output signals and from the power supply.
The module configuration is possible via the USB PORT or one of the available RS-485 interface ports with the use of free eCon software.
The RS-485 inteface can be connected via the connection terminals but also via the connections on both sides of the module under plastic covers which need to be removed for access. The lateral interface donnections offer the advantage that other modulse which also have side interfaces can easily be connected to each other using an optional inter-modular connector.

The S4AI module has the following features:

analogue inputs (current / voltage or resistance / shunt / thermocouple, depending on the module variant)
programmable individual characteristics of the inputs
MODBUS protocol on RS485 interface
timers of lower and higher threshold overrun duration for each input of the module
