Symbio 800 Power Supply Requirements
Power the Symbio 800 controller as follows:
• The PM014 power supply module, through inter-module-communication, is the preferred
method of powering the Symbio 800 controller.
– PM014 Output: 1.4 A max at 24 VDC at 70°C. Refer to the PM014 Power Supply IOM (BAS-
SVX33).
• Any 24 VDC power supply can be used if it has sufficient power output, as shown in Figure 5,
p. 17 .
– Any user-provided power supply must provide power for three line cycles if AC power is
interrupted. This can prevent controllers from rebooting with shorter, but more frequent,
power losses.
• Powering the Symbio 800 from a XM70, or XM90 Expansion Module is not advised.
If the max operating temp is 60°C or less, the current draw for the Symbio 800 is 400mA
@24VDC, which includes up to 1000mA of current supplied to the 5 Volt USB Host ports. At max
operating temperature of 70°C, the current on the USB Host ports is limited to 500mA. See
Table
4, p. 17 .

Direct Current Requirements for Symbio 800 and Peripherals
The Symbio 800 output is 24 Vdc. The table below provides the current draw per component for
DC power budgeting.
