AVAILABLE I/O MODULES
Individual electrical connection diagrams are given in section ELECTRICAL
INSTALLATION .
4.1 Base set
Each device is composed of:

housing,

front panel with touchscreen colour LCD, LED diode and USB port (type
– A),

the basic M module, which is made up of:

USB port (type
– A) – second port,

USB port (type
– B mini) – service,

Ethernet port,

RS-485 communication interface connector,

Power supply from 24 VDC.
Depending on the client needs, in the device can be installed up to seven input/output
modules. Detailed technical descriptions of individual modules are given in section
TECHNICAL SPECIFICATIONS .
4.2 IN6I(24V)
– six channel 0-20mA or 4-20mA input type module

standard current loop inputs 0-20mA or 4-20mA for passive or active transducers (internal
24 VDC voltage source for loop power supply),

linear current measurement within the range or sub-range of -20 .. +20 mA,

galvanic separation from the remaining device circuits, no separation among the input
channels,

each input has a separate four-pole plug-in terminal block,

two colour LED informing about the module's operating status.
Note: The maximum number of IN6I(24V) modules in the device: 4.
