Therefore, the following measures are mandatory for a successful installation and operation:
•Use shielded cables for all signal and control input and output lines.
•Cables for digital controls (digital I/O, relay outputs) must not exceed a length of 30 m and are
allowed for in building operation only
•Use shield connection clamps to connect the cable shields properly to earth
•The wiring of the common ground lines must be star-shaped and common ground must be
connected to earth at only one single point
•The unit should be mounted in a metal enclosure with sufficient distance to sources of
electromagnetic noise.
•Run signal and control cables apart from power lines and other cables emitting electromagnetic
noise.

Dm350_01a_oi_e.docx / Jul-23 Seite 8 / 57
Introduction
The DM350 is a unit for connecting one DMS full bridge sensor, whose converted measured values
are available at an analog output (current/voltage) and at four control outputs (depending on the
option).
Optionally, an RS-232 or RS-485 communication interface with LECOM or MODBUS protocol is
available.
The Control outputs transmit the rising above, the falling below of switching points, as well as
movements outside of a range. A DMS error can also be detected.
The COM+ connection determines the voltage level of the control outputs. At 24 V this corresponds to
the HTL level.
The HTL Control inputs can be used to release the self-holding at the outputs.
Furthermore, a set function of the analog output can be realized via the HTL Control inputs.
Optionally, two relay outputs can also be used as outputs.

Dm350_01a_oi_e.docx / Jul-23 Seite 9 / 57
Electrical Connections DM350
The terminal screws should be tightened with a slotted screwdriver (blade width 2mm).
DC Power Supply (GND, 24V)
The unit accepts DC supply from 18 to 30 V at the terminals 1 (GND) and 2 (24V). The power
consumption depends on the level of the supply voltage with approx. 100 mA and the additional
bridge current required from the bridge voltage supply output.
DMS Full Bridge Supply (SUP+/-)
With the terminals 4 (SUP-) and 5 (SUP+) the DMS sensors can be supplied by a programmable bridge
supply voltage of 3V - 10VDC with max. 50 mA.
DMS Full Bridge Readback (MEA+/-)
With the terminals 8 (MEA-) and 9 (MEA+) the DMS sensor bridge supply voltage can be read back.
These terminals must be connected with SUP ± in any case, ideally directly at the full bridge, in order
to avoid voltage drops at the supply line. Read back is via monitor (page 0) by code <2.
DMS Full Bridge Voltage (BRI-/+)
With the terminals 6 (BRI-) and 7 (BRI+) the DMS bridge voltage can be evaluated.
The bridge voltage in units can read back via monitor (Page 0) by the codes <4 and <5.

Dm350_01a_oi_e.docx / Jul-23 Seite 10 / 57
Example of Connection DMS Sensor
The picture below shows an example of the connection of a DMS sensor.
(SUP = Supply, MEA = Measurement Supply, BRI = Bridge Voltage)
Control Outputs (Ctrl. OUTx, COM+)
At the terminal 20 to23 (Ctrl. OUTx) four control output signals are available. Terminal 19 (COM+)
supplies the outputs and thus determines the voltage level at the output. The outputs can transmit
different states by the parameterization and are designed as high-side drivers. The status of the
outputs is directly visible in the Outputs field of the OS.
The switching states is displayed (display with unit and status bar) as C1 to C4.
Control Inputs (Ctrl. INx)
At the terminal 10 to12 (Ctrl. INx) three control inputs with HTL PNP characteristic (internal pull-down
resistor) are available. The inputs can be used for HTL control signals. They can be programmed for
different functions depending on the parameterization. The status of the inputs is directly visible in
the Inputs field of the OS. The circuit below shows a PNP circuit.

Continuation “Control Inputs (Ctrl. INx)“:
Analog Outputs (AGND, 20 mA, ± 10V)
At the outputs of the terminals 13 to 15 (AGND, 20 mA, ± 10V) a voltage output ((+/-10V, 0-10V) and a
current output (0-20mA, 4-20mA) are available. The voltage output is located at the terminals 13 and
15, and the current output at the terminals 13 and 14.
Attention:
Only either the current or the voltage output may be used.
Serial Interface (GND, RxD/B, TxD/A)
A serial interface (RS232 or RS485) is available at terminal 16 to 18 (GND, RxD/B, TxD/A).
The following drawing shows the connection to a PC by using a standard Sub-D-9 connector:
