S4ai

- MOdUlE Of ANAlOg iNPUTS

• Processing 4 analog signals (standard signals, resistance thermometers, thermocouples)

to RS-485 Modbus.

• 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.

• To be mounted onTS35 rail in typical installation cabinets.

• galvanic isolation between inputs divided into 2 groups of 2 inputs

• Possibile configuration via USB (power supply of the module is not required).
