Lumel-S4AI
Module of 4 analog inputs

S4AI is a module of 4 analog inputs dedicated to convert standard signals (current, voltage, temperature, resistance) into digital RS-485 signal with Modbus protocol. The input signals are divided into 2 sets of 2 inputs, which are isolated from one another. RS-485 and USB ports are isolated from input signals and the supply. The module setting can be easily done through USB or one of the RS-485 interfaces using the free e-Con program. programmable individual characteristics of the inputs. operation in Modbus Slave mode. possible connection via the internal RS-485. two programmable alarm outputs. mathematical functions: addition, subtraction, multiplication, division, average, minimum, maximum. two virtual measurement channels to perform mathematical functions on the channels or between the measurement channels. programmable operating time counters. possibile configuration via USB (power supply of the module is not required) modular design and is dedicated to be mounted on the S-type rail acc. to EN 62208 ( module’s width is equal to 3 standard modules). It is perfect to be mounted  in a switchboard cabinets. external dimensions: 53 X 110 X 60 mm
