5. DL7 MODULES

Individual electrical connection diagrams are given in section
INSTALLATION.

5.1 DL7 basic kit

Each DL7 device is composed of the following:
 case
 face plate with an LCD display and USB port type A
 basic M module

5.2 Basic M module

The basic M module is made up of the following:
 USB type A port,
 Ethernet port,
 RS-485 communication interface connector,
 mini USB B socket with a button – for maintenance,
 connector for connecting the device to power supply.

5.3 The 0/4-20mA inputs modules DL7-IN6I(24V)

 interfacing with the passive transducers with standard 0-20mA or 4-20mA output,
transducers supplied with 24 VDC,
 linear current measurement within the range or sub-range of -20 .. +20 mA,
 6 measurement inputs galvanically separated from the remaining circuits.
 each input has a separate pin type four-wire terminal block.
 a two-colour LED diode informing about the module's operating status.
CAUTION: The maximum number of modules in the device – 4.

5.4 The 0/4-20mA inputs modules DL7-IN6I

 interfacing with the active transducers with the standard current output 0/4-20mA (or
passive transducers with additional external power supply),
 linear current measurement within the range or sub-range of -20 .. +20 mA,
 6 measurement inputs galvanically separated from the remaining circuits.
 each input has a separate pin type four-wire terminal block.
 a two-colour LED diode informing about the module's operating status.

5.5 The RTD inputs modules DL7-IN6RTD (DL7-IN3RTD)

 temperature measurements using the Pt, Ni, Cu, KTY type sensors (a complete list of
sensors is given in the chapter discussing the technical data),
 linear measurement of the resistance within the range or sub-range 0 .. 4000 Ω,
 6 (3) measurement inputs galvanically separated from the remaining circuits.
 each input has a separate pin type four-wire terminal block.
 a two-colour LED diode informing about the module's operating status.
