Page 20: Example Wiring
HCFA Corporation Limited 4.5 Example Wiring 4.5.1 AC Power supply *1 It is recommended to use the same power source to power the main unit, powered extension units and special function blocks/units. If two sources are required, follow the below guidelines: - Supply power to the powered extension units and special function blocks/units before or at the same time the main unit is powered. -
Page 21: Dc Power Supply
HCFA Corporation Limited below guidelines: - Supply power to the powered extension units and special function blocks/units before or at the same time the main unit is powered. - The power supplies may be cut the same time after ensuring system safety. -
Page 22: Service Power Supply
HCFA Corporation Limited 4.6 Service Power supply An AC powered HCA2can supply a service current of 24V DC at 400mA when used on its own and, when used with extension or special function blocks. A DC powered HCA2does not have the capacity to supply a service current. However Additional extension blocks can be powered from the main units power supply. -
Page 23: Typical Wiring
HCFA Corporation Limited 5.1.1 Typical Wiring Note: The input circuit power supply provides a clean +24VDC supply for the inputs. Hence use an external +24VDC power supply at your own risk. The input circuit power supply cannot provide a service supply to special function blocks (SFB). -
