Manual Power Monitor, PD 3260 1/79
1 General information.
The PD 3260 Power Monitor is a member of the 3000 series of modules from PROCES-DATA.
It provides a three-phase Power
Line Monitor and Generator Switch
Controller interface to the P-NET
Fieldbus EN50170 Vol 1.
The monitoring functionsoffered by
the module are useful for assessing
the operation of electric generators,
and for monitoring loads connected
to three-phase power lines, or those
having up to 3 single phases.
The generator switch functions are
designed to perform phase, speed
and acceleration controlled switch-
ing of synchronous or asynchronous
generators, connected to three-
phase power lines.
Switching is performed using the Digital Output Channels or via the Thyristor Switch Channel.
P-NET is a fieldbus network, designed for process control and data collection. The PD 3260
module has been developed to directly interface with digital process signals.
Configuration of the module for the functions required, and communication between the module
and a control computer, is carried out via the P-NET fieldbus. The PD 3260 module can be
controlled via P-NET, or it can operate as an autonomous unit.
The module possesses a programmable Calculator, which can be purpose programmed to control
the digital outputs and monitor the digital inputs. The Calculator can operate on a variety of
variable types, such as reals, integers, bytes, booleans, timers and arrays. User programmes can
be devised to produce application specific functions, such as digital control loops, and PLC
functions may be set up for use in a wide variety of local autonomous process applications.
The compact design and outstanding environmental specifications for the Power Monitor, makes
it an ideal process component in industrial, as well as less stringent environments.
