EN1R-0144GE51 R1007 14
IMPORTANT
We recommend installing a fuse on the secondary side of the transformer
in order to protect the devices against miswiring.
Line Power Supply
The Excel 100C Controller is powered by an external transformer.
Transformer requirements for one Excel 100C Controller:
Secondary
Voltage 24 Vac
± 20% or 21-28 Vdc
Current 1.1 A
Power 15 VA (Excel 100C, only; no MCE/MCD)
25 VA (if fully equipped with MCE/MCD)
The transformer, already installed in the cabinet, can be used to supply several con-
trollers, communication devices, or peripherals (e.g. actuators, etc.) – provided it
delivers sufficient power.
For detailed information on transformers to be used in accordance to regional
requirements, please refer to the U.S. and European Specifications chapters.
