Beckhoff C63xx industrial computer power supply and shutdown configuration

After the industrial computer detects that PC_SON is at a high level, it triggers the operating system to execute a secure shutdown process (equivalent to Windows' "Start → Shutdown").

After the operating system completes shutdown, the Power Status (pin 2) switches from 24V to 0V - this signal can be used to drive external contactors or relays.

After the external circuit detects that the Power Status is 0V, it can safely cut off the main power supply (disconnect the 24V power supply to pins 6/7), achieving a complete system power outage.

Engineering value:

This mechanism avoids data loss or file system damage caused by directly cutting off the power supply of the industrial computer.

The feedback signal from Power Status enables the upper PLC or control cabinet main contactor to accurately sense the completion time of shutdown, thereby achieving a fully automated process of "pressing the shutdown button → automatic system shutdown → automatic disconnection of the main power supply in the cabinet".

2.3 Assembly process of power connector (stress relief shell)

The 5-pin connector equipped with C63xx-0020 requires users to assemble it themselves, and the assembly of its Strain Relief Housing directly affects the reliability of the cable in vibration environments. Please follow the following procedure:

Step 1: Wire stripping and pin connection

The stripping length of the wire is 8-9mm.

Maximum allowable wire diameter: 1.5 mm ² (approximately AWG 16).

Insert the wire end into the 5-pin plug according to the pin definition and tighten the screw.

Step 2: Stress relief shell assembly

Thread the lacing cord into the reserved slot on the lower half of the stress relief shell.

Insert the pre wired 5-pin plug into the lower half of the casing.

Tighten the cable tie and cut off any excess plastic ends to firmly secure the cable to the casing.

Buckle the upper part of the shell onto the lower part, and hear a "click" sound to indicate that it is locked in place.

Key engineering constraints:

When the length of the power cable is long, it is necessary to calculate the voltage drop - to ensure that the voltage reaching the power plug of the industrial computer is not less than 22V (the lower limit allowed for rated 24V). Using a 1.5mm ² cable can minimize the voltage drop during long-distance transmission.

An external 24V power supply must be equipped with a 16A fuse as line protection.

Chapter 3: Mechanical Installation and Heat Dissipation Space Requirements

3.1 Preparation for installation of control cabinet

The C63xx series industrial control computer is fixed inside the control cabinet through a mounting plate. Depending on the model, the mounting plate can be installed on the rear wall or right side wall (see Chapter 7 for specific location in the assembly dimension diagram).

Before installation, it is necessary to confirm:

The control cabinet wall has been machined with four fixed bolt holes according to the assembly dimension diagram.

At least 50mm of ventilation space should be reserved above and below - for fanless models (C6320/C6325/C6335), natural convection heat dissipation relies entirely on air circulation above and below.

The ventilation duct must not be obstructed, otherwise it may cause equipment overheating, frequency reduction or damage.

3.2 Grounding specifications

There is a dedicated grounding point on the top of the industrial computer chassis. During installation, a low impedance connection must be established:

Use copper braided tape or a wire with sufficient cross-sectional area to connect the grounding point to the central grounding point of the control cabinet.

The purpose of grounding connection is to discharge common mode interference coupled by external power lines and signal lines, ensuring that EMC performance meets the requirements of EN 61000-6-2/6-4.

Chapter 4: Interface Layout and Peripheral Connection

All interfaces of the C63xx-0020 series are located at the top of the chassis, making it easy to exit from the top of the cabinet.

4.1 List of onboard interfaces

USB 1/USB 2: Two USB 2.0 interfaces, mainly used for connecting CP68xx/CP78xx control panels (touch screen data and keyboard communication).

USB 3: The third USB 2.0 interface is used to connect other peripheral devices such as USB drives, code readers, keyboard/mouse receivers.

Network (LAN1/LAN2): Two 10/100/1000BASE-T RJ45 Ethernet interfaces - one can be dedicated to EtherCAT real-time communication, and the other is used for upper computer network connection or factory network access.

DVI-II interface: used to connect CP68xx/CP78xx control panel (video signal). To connect a VGA monitor, an adapter is required:

C9900-Z411: DVI-I-VGA plug adapter

C9900-Z413: DVI-I-TVI and VGA Branch Cable (15cm)

RS232 COM2: 9-pin Sub-D serial port, used to connect old serial devices.

4.2 Matching advantages with CP68xx/CP78xx control panel

The original text emphasizes that the C63xx-0020 is an ideal combination with the DVI/USB control panel (CP68xx or CP78xx). The advantage of this pairing is that:

Single cable video+USB: DVI transmits display signals, USB transmits touch screen and keyboard data, two cables can complete panel connection.
