3-3.1.1 Power Input
The Genesis II Direct Digital Controller's power requirements are one of the following:
• 24VAC ±10%, 50/60 Hz, Power Consumption: 15 VA.
• 24VDC ±10%, Power Consumption: 8 Watts.
The operating voltage must meet the requirements of Safety Extra Low Voltage (SELV) to EN60730.
The transformer used must be a safety transformer in compliance with EN60742 and be designed for
100% duty. It must also be sized and fused in compliance with local safety regulations.
A single transformer may be used to supply voltage to more than one unit (such as a Genesis II Direct
Digital Controller and associated Remote Expansion Modules) providing the planned load is well
within the transformer’s rating. The transformer output terminal designated as AC Neutral must be
solidly earthed to the enclosure’s main earth link.
Power input terminals are Terminals 1, 2 and 3 and are detailed below in Table 3-2.
Terminal AC Supply DC Supply
1 24VAC +24VDC
2 0VAC (Neutral) 0VDC
3 Earth Earth
