Supplying external devices.
 | Comply with the maximum power consumption The total power consumption of the Embedded PC and any device connected to the Embedded PC may not exceed 100 W. Measure the maximum power consumption as follows:
|
A further device, e.g. a control panel or a monitor, can be connected to the CX2100-0914 power supply unit. To do this, use the X940 BAT connection (+24 V, 0 V, earth) on the power supply unit. The device is supplied with 24 V DC and a maximum of 48 W. The output is not short-circuit proof and must be protected with a 2 A fuse.
Requirements:
- Cable for the power supply (+24 V, 0 V, earth) with a 1.5 mm² conductor cross-section.
Connect further devices as follows:
- 1. Switch off the supply of power to the power supply unit.
- 2. Configure the cable (+24 V, 0 V, earth) and mount the cable on the plugs supplied.
- 3. Make sure that the plugs are configured correctly (+24 V, 0 V, earth).
- 4. Protect the external device with a 2 A fuse.
- In normal operation, the CX2100-0914 power supply unit supplies power to the external device. If you use a battery pack, the device will continue to be supplied with power in the event of a power failure. Comply with Behavior in the event of a power failure.
Behavior in case of a power failure
In the event of power failures, the voltage briefly drops to approx. 15-16 V before increasing again to 24 V. There are technical reasons for this behavior, which may lead to problems with connected devices. Be aware of this behavior for your device configuration.
