Compact Power Transducer CPT DIN
Basic and Advanced functions
CPT DIN is a compact transducer available as a Basic
version for measurement and data retransmission and as
an Advanced version with many kinds of outputs and PLC
type control functions suitable to be used also for critical
applications. This unit for 3-phase and single-phase
systems is recommended for the measurements of both
main electrical variables in electrical distribution systems
and on board of machines as working survey equipment.
Moreover it represents an excellent compromise among
price, value and features.
The most important benefits in the advanced version are:
• Integrated and extended AC and DC power supply for
full application coverage.
• Metering of both total and partial active and reactive
energies in order to survey both load parameters and
consumptions.
• Hour counter function for machine maintenance planning.
• RS485 communication port (with iFIX SCADA
compatibility) for data transmission to PC, or pulse or
analogue outputs to PLC. All of them for remote
monitoring and control of the variables.
• Dupline bus compatibility for full Building automation
integration.
• OR, AND, OR+AND control of up to 16 selected
variables to grant together with the asymmetry, phase
sequence and phase loss functions an extended load or
line control by means of 2 digital outputs.
• Combination of RS485 port and 1 digital output
