Solutions Handbook (AADvance Controller)

Power Supply Requirements

A controller requires the following power supply sources:

 A dual redundant power supply of + 24V dc with an operating range of 18V dc to

32V dc.

Note: An AADvance controller is designed to accept supply transient and interference

according to IEC 61131 part 2.n

An over current fault in the controller must not result in the whole system losing

power. Consequently, the power sources must be able to deliver the peak current

needed to open any over current protection devices (such as fuses) without

themselves failing.

The power supply protection of the controller is within the modules, the power

distribution arrangement must provide a circuit breaker on the input side of each

power source.

Note: A controller is designed to withstand a reverse polarity connection without

permanent damage.

The power sources should come from a commercially available industrial un-

interruptible power supply (UPS) system. A suitable UPS should have capacity sufficient

to meet the entire system load (including field devices as well as the controller) and a

suitable contingency allowance for any projected future expansion.

Adding Cable Management

The field, power and other system wiring will be connected to terminals along the top

of the base units. It is recommended a length of trunking or similar be located above

each set of base units, for cable management.
