CROMPTON INSTRUMENTS Integra 1560 and 1580 Digital Transducer Systems

Description

Integra 1560 and 1580 transducers provide high accuracy <0.2% measurements and communicate up to 50 major electrical and power quality parameters, including true RMS system values, power quality data and total harmonic distortion (THD) measurement up to the 31st harmonic. The range includes the rail mounted 1560 DIN version and the 1580 variant with a base plate for surface mounting.
Operation
The multi function Integra 1560 and 1580 transducers offer uncomplicated operation and high accuracy <0.2% measurement of single and three-phase voltage, current, frequency, Watts, VAr, VA, energy and power factor, and total harmonic distortion measurement of both phase and system current and voltage. A simple Windows based software package is provided to configure the transducer. Once configured, up to 50 electrical and power quality variables can be simultaneously input into building management systems via pulsed, analogue and digital communication options. Status may also be monitored via a PC through a software package.
Alternatively, an optional menu driven display unit can be used to configure and monitor up to 32 measured parameters. Display panel unit can be permanently mounted next to the transducer or simply connected at times when configuration, adjustment and/or status information is required.
Accuracy
Integra transducers utilise true RMS measurement techniques up to the 31st harmonic, providing <0.2% accuracy. An exceptional tolerance to high harmonic frequencies is achieved from the robust frequency detection method, which is able to lock the fundamental frequency onto any phase. High integrity measurements are possible where the system approximates CT current in the absence of voltage signals.
System Input
Designed for all low, medium and high voltage switchgear and distribution systems, the transducers offer programmable VT and CT ratio capability. Direct connection up to 480V AC with 5A CT inputs is standard, and 1A CT inputs are optional.
System Outputs
Pulsed outputs
Optional pulsed outputs enable retransmission of kWh and kVArh time based parameters. Outputs are pulsed at a rate proportional to the measured kWh active energy, with programmable pulse width and rate. Output relays have fully insulated volt free contacts, with connection via screw clamp terminals.
Analogue outputs
Up to four analogue outputs may be included, enabling transmission of linear parameters. Each analogue channel can be assigned to one of 47 measured parameters with fully adjustable output span and can be configured to operate in normal, reverse, threshold or constant current modes. Analogue outputs share a common return which is galvanically isolated from non-analogue output terminals.
RS485 Digital Communications
RS485 Modbus RTU
Integra 1560 and 1580 transducers have two RS485 communication ports for direct connection to SCADA systems with Modbus RTU protocol, or optionally a single Johnson Controls Metasys NII protocol. The Modbus option includes function 8 subfunction 0, which provides return query data diagnostic support and the ability to change Modbus word order to suit user requirements.
Lonworks Option
The Lonworks option conforms to LonMark Interoperability Guidelines version 3.2. Transducers can be integrated into a single control network without requiring a custom node or network tool development. Lonworks implementations include a Modbus port. This Modbus port is used when a local Integra display is required or for setting up the unit from Crompton Instruments configuration software.
