Description

2-CHANNELS MODULE OF ANALOGUE INPUTS

The SM1 – 2 channels module of analogue inputs is destined to convert standard signals, resistance or temperature signals into numerical data accessible through the RS-485 or RS-232 port by means of the MODBUS protocol.

The SM1 2-channel module of analog inputs 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 measurement is carried out independently in two channels. RS-485 and RS-232 output ports are galvanically insulated from input signals and the supply. The module programming is possible by means of the RS-485 or RS-232 port.

In the set of SM1 module there is a connecting cable, to connect with the PC computer (RS-232).

The SM1 module realises following functions:

• mathematical operations on channels and between measuring channels,

• conversion of measured or calculated quantities basing on the individual linear characteristic,

• storage of maximal and minimal values for both channels,

• programming of the measurement averaging time,

• servicing of RS-485 and RS-232 interfaces in MODBUS protocol, both in ASCII and RTU mode.
