    Description

    SM2, RS-485 MODBUS Module with 2 Analogue Inputs

    The SM2 4-channel module of analogue inputsfrom LUMEL is destined to convert standard signals, resistance or temperature signals into numerical data, accessible via the RS-485 or RS-232 port by means of the MODBUS protocol.
    The measurements are carried out independently infour channels. The RS-485 and RS232 output ports are galvanically isolated from the input signals and the supply voltage. The module programming is possible by means of the RS-485 or RS-232 port via the free eCon software.

    An interface cable for the connection of the module witha computer (RS-232 with D9 plug) is supplied with the SM2 module.

    TheSM2 module realisesthe following functions:

    • Mathematical operations on channels and between measuring channels
    • Conversion of measured or calculated quantities based on the individual linear characteristic
    • Storage of minimum and maximum values for both channels
    • Programming of the measurement averaging time
    • Pragrammable digital filters, independent for each channel
    • 2 programmable open-collector alarm outputs
    • Servicing ofRS-485 and RS232 interfaces in MODBUS protocol, both in ASCII and RTU mode
