2Product description
The DHCON DRC Compact is a universally usable computer for control and connectivity tasks and can be used as
gateway, router, or soft-PLC due to its variety of industrial interfaces. Due to its compact and robust design, it fits
perfect to industrial surroundings. The DRC Compact controller differs from other available devices due to two
special features:
▪Modular communication interface extensions
It is possible to choose between the second RS485 interface or RS232 interface or CAN.
Depending on the chosen configuration the board has one of the three interfaces above available.
▪Optional WiFi/BT connectivity
A configuration of the DRC Compact with WiFi/BT connectivity is also available. The device is fully certified
and supports all of the needed standards.

3.4 User group
The device may only be used by trained specialists. The specialists can carry out the tasks mentioned in Chapter
3.2 independently. In case of failures and for maintenance tasks, please contact a technical sales employee.
3.5 Danger
Inappropriate use of the device can lead to damage of objects or the injury of people. Therefore, please make sure
to bear in mind the safety instructions included in the user manual and do not deviate from the recommended
measures, especially regarding commissioning and decommissioning, maintenance, or in case of failure.
3.6 Special precautionary measures
If you comply with the precautionary measures contained in the user manual and take into account warning and
safety indications, you should be able to operate the device without problems. Should you ever be under the im-
pression that a secure operation cannot be guaranteed, disconnect the device from the power supply as quickly
as possible and contact a technical sales employee.
4Prepare the use of the product
The following paragraph describes the correct approach before the actual use of the product.
4.1 Transport and storage
All products of DH electronics are delivered in professional packing. In any case, the products are protected from
vibrations; if necessary, a special ESD packaging is used. Our products may only be transported and stored in the
provided original packaging, as only then can a high product quality be guaranteed for a longer transport or stor-
age period. The scope of delivery should be controlled when the product is unpacked; afterwards, the packaging
has to be disposed appropriately. The customer is responsible for this.
4.2 Disposal of product and packaging material
Packaging material always has to be disposed appropriately by the customer. In addition, he is responsible for
disposing of the delivered product after termination of use at his own expense according to
legal regulations. The customer indemnifies DH electronics GmbH from the take-back obligation and related
third-party claims. Should the product be passed on to third parties, the customer must instruct these third
parties by contract regarding taking over the duty of disposal and reiterating this duty. Should the customer re-
frain from doing so, he is obliged to take the delivered product back after termination of use at his own expense
and to dispose of it according to legal regulations.

4.3 Preparation of the installation
Safety information
▪In electric systems, voltages can occur that are dangerous for people.
When live parts are touched, this can lead to an electric shock.
▪Make sure that the device is disconnected from the power supply.
▪
Do not supply the device via an alternating current network.
▪The device has to be grounded before use.
▪Do not drop the device.
▪Make sure that the ventilation slits of the housing are not covered and bear below instal-
lation instructions in mind!
▪The device must not be operated in inflammable or explosive surroundings.
Installation instructions
The device is clipped into a DIN rail by means of a clip on the bottom of the housing. For this purpose, put the
device onto the side opposite the clip and then push it down. The device may only be installed horizontally; a de-
viating installation is not permitted.

4.4 Setup
The device is delivered in an operational condition. For setting up the device, proceed as described in the follow-
ing paragraph and bear in mind the safety instructions from Chapter 3.
▪Make sure that the power supply on the customer side is switched off at first.
▪Put the device into the DIN rail (see Chapter 4.3).
▪The device has to be grounded before use. For that purpose, connect X1 with the protective conductor.
For the power supply of the device, use a +12/+24 VDC power supply unit.
Do not supply the device with alternating voltage.
▪Connect the negative lead of the power supply with X1-GND.
▪Connect the positive lead of the power supply with X1-24 V.
▪Switch on the supply voltage.
▪The device will boot automatically.
5Operation
Bear in mind the safety instructions from Chapter 3 and the instructions for setup from Chapter 4.4. To guaran-
tee a secure operation, the device must only be used by trained staff according to Chapter 3.2.
5.1 Interfaces
The device contains various interfaces, which are listed and described briefly in the following.
5.1.1 Power supply
▪The device is supplied via a power supply unit with +10,8 to 26,4 VDC; for this a pin header with 3 poles is
used. A supply with alternating voltage is not permitted.
▪Input voltage is protected against polarity reversal, the input current is limited to 2,5 A.
▪The current limit is carried out by a 2,5 A fuse. Should you suspect it to have blown, please contact us im-
mediately.
