Bently Nevada ORBIT 60 SERIES Power Input Modules

Description

The Power Input Modules (PIM) always reside in a special

purposed slot located in the first slot of the chassis. This slot

accommodates two PIMs for redundancy.  At least one PIM

must power every chassis, and every chassis requires its own

PIMs and power sources. Redundant PIMs and power sources

are strongly recommended.

The PIM is a half-height module that connects an external

power source to the system. Each Orbit 60 Series chassis

supports two stacked redundant power input modules.

Failure of one power source does not affect the operation if

the system uses both power inputs. The PIM employs out-of

range protection for miswiring, overvoltage, and overcurrent

protection for the input power sources.

The PIMs support input voltages ranging from +21 Vdc to +32 Vdc.

The most common power source comes from external DIN rail mounted

AC/DC +24 Vdc output power supplies.

The Instrument Common(IS) and Protective Earth connections for the

system are made at the utility side of the PIM.

External redundant power supplies are recommended for the system.

Remove and insert a single Power Input Module without disrupting system operation,

as long as another PIM remains installed and connected to its input power source.
