1. Introduction
Please check the packaging and contents for damage and completeness before commissioning.
Should any defects occur, please inform us immediately.
• Does anything on the packaging indicate that anything was damaged during transport?
• Are there any signs of use on the device?
Under no circumstances may you operate the device if it is damaged. If in doubt, contact our technical
service department.
Please read this manual carefully before installing the appliance!
1.1 Scope of delivery
• ALLDAQ card of the ADQ-40 series incl. mating connector

1.2 Safety instructions
Be sure to observe the following instructions:
• Never expose the appliance to direct sunlight when operating.
• Never operate the appliance near heat sources.
• Protect the device from moisture, dust, liquids and vapours.
• Do not use the device in damp rooms and under no circumstances in potentially explosive areas.
• Repairs may only be carried out by trained, authorized personnel.
• Please observe the installation regulations and all relevant standards (including VDE standards)
when commissioning the instrument, especially when operating with voltages greater than 42 V.
• We recommend to always connect unused inputs to the corresponding reference ground to
avoid crosstalk between the input channels.
• Always disconnect your eld wiring from the voltage source before you make or break cable
connections to the card.
• When handling the card, make sure that no static discharge can occur through the device. Follow
standard ESD protection measures.
• Never connect the devices to live parts, especially not to mains voltage.
• Precautions to avoid unpredictable misuse must be taken by the user.
ALLNET® GmbH Computersysteme is not liable for improper use and resulting
damage.
Make sure that the unit is very well ventilated, as the cooler can be-
come as hot as 170°C at full load.

Introduction
1.3 Installation and assembly site
The ADQ-40 series is designed for industrial use. The board may only be used in dry rooms.
Ensure adequate ventilation. Make sure that the connection cables are securely attached.
1.5 Control
• ALLDAQ ADQ-LINK-BUS
• For control please use the ALLDAQ ADQ-SCU or ADQ-153.
1.4 Brief description
The programmable current sinks of the ADQ-40 series are suitable for use in industrial automation
and measurement technology. The board is supplied in a trough, which allows mounting on a DIN-
rail according to EN50022. Load programming can be implemented either by ADQ-LINK data bus, by
external analog control signal or by integrated potentiometer.
Depending on the version, 2, 4 or 8 potential-free sink channels are available.
Features:
• Potential-free sink channels (connectable in parallel)
• Isolating relay in main current path
• AUX paths (switchable base load 120Ohm) protected by polyfuse
• Individual temperature emergency shutdown per channel
• Voltage (Usense and Usense) up to 20.48V (opt. 40.96V)
• Max. 25W Continous (Usink x Isink <= 25W; max Isink = 5A)
• Max. 100W peak power (max 5sec.)
• Internal current measurement from Isink is measured via a 20mO Shunt
• MMCX connector for external measurement of Usink and Isink (over 20mOhm shunt)
• Channel-specic alert function for Usink, Isink and temperature shutdown per channel
• Fan output (12V/1A) controllable by software
• Heat sink temperature readable via software

2.1 Connection
The box should be handled with care to ensure that the device is not damaged by electrostatic
discharge (ESD), mechanical stress or excessive current surges. Precautions should also be taken to
avoid electric shock. Follow standard ESD protection measures.

3.3 Control options
When switching to a manual control option, make sure that the main relays are switched via jumper J1
before powering up or sinking the current. If this is not done, there is a risk of damageing the relays.
3.3.1 ALLDAQ ADQ-LINK Bus
Control via the ALLDAQ ADQ-LINK Bus is the recommended method of control for the ADQ-40 series.
To do this, use the ADQ-4X app from the ALLDAQ driver. In addition to this APP, control via an API
library is also possible. It allows full control over all functions of the ADQ-40 series.
To activate this option, jumper J1 must be in the left position and the channel jumper must be in the
lower position.

3.3.2 Integrated potentiometer
With the analog control of the ADQ-40 series via the integrated potentiometers, the range of
functions is limited to the simple setting of a current. The temperature emergency stop is also active
to protect the hardware. All other functions cannot be operated in this control option.
To activate this option, the jumper J1 must be in the right position and the channel jumper in the
upper position.
3.3.3 External control line
With analog control of the ADQ-40 series via an external control line, the range of functions is limited
to the simple setting of a current. The temperature emergency shutdown remains active to protect
the hardware. It is also possible to measure the shunt voltage and the sense voltage via external
measuring devices. All other functions are not available in this control option.
The control voltage is in the range of 0V - 4.096V. The sense current results from the following cal-
culation:
Ucontrol = 2.048 + 0.00038*Sink (sink in mA)
To activate this option, jumper J1 must be in the right position and the channel jumper must be
removed.
