Short Description

The Processor Module is a central unit for AC500 with high performance.

Each Processor Module can operate up to 2 Communication Modules through its communication module interface. The Communication Modules are mounted on the left side of the Processor Module. On the right side of the Processor Module, up to 10 digital or analog I/O expansion modules can be attached. Each of these I/O Modules require its own I/O Terminal Unit, whose type depends on the module type.

Note

Mounting, disassembling and electrical connection for the I/O Modules are described in detail in the S500 System Data chapters Mounting and Disassembling the Processor Module PM595.

Warning

:strong:Removal/Insertion under power

The devices are not designed for removal or insertion under power. Because of unforeseeable consequences, it is not allowed to plug or unplug devices with the power being ON.

Make sure that all voltage sources (supply and process voltage) are switched off before you are

• connecting or disconnecting any signal or terminal block
• removing, mounting or replacing a module.

Disconnecting any powered devices while energized in a hazardous location could result in an electrical arc, which could create a flammable ignition resulting in fire or explosion.

Be sure that power is removed and that an area has been thoroughly checked to insure that flammable materials are not present prior to proceeding.

The devices must not be opened when in operation. The same applies to the networking interfaces.
