1 itronics Digital Power Transducer i t r o n i c s D / 3 r i o n The itronics instrument is a utility-grade, three-phase, digital power transducer that connects directly to instrument transformers. Direct-connect high-voltage inputs are also available. The design and components are field-proven in the substation environment with all inputs transformer isolated. The multiple microprocessor design uses advanced digital signal processing for true MS measurements including power. This instrument is a multifunction transducer that calculates Voltages, urrents, Power (real, reactive, apparent), Power Factor, Frequency, and Energy Values. eal-time Harmonics, K-Factor, Displacement Power Factor, and Demand measurements with Min/Max memory are also available. The itronics instrument is an Intelligent Electronic Device (IED) and stores these measured values in internal registers for serial communication access. The itronics instrument is designed to meet IE standard 1010 and is certified by Underwriters Laboratory to meet UL and S standards. Features Multiple measurements with accuracy and fast response Demand/Min/Max values with local/remote reset Direct connect up to 480V ac Supports input from reference potential Field-selectable element switch S-485, S-232, Modbus physical ports Modbus TU, DP3, Modbus protocol nalog utputs (with optional ) Universal Power Supply option a single supply that operates from 24, 48, 125, or 250V dc source or 115V ac service Self-diagnostics, network accessible outine calibration not required enefits to Design Engineers Precise and timely measurement of all needed parameters Easy to use and mount without expensive panel rework Simple connections for transmitting values to serial, analog or mixed systems. o post installation headaches with rugged, utility grade design Lowers purchase, installation and operating costs Precise and Fast Measurements The itronics transducer is a precise instrument for measuring multiple electrical parameters. True MS measurements are standard and accommodate signals containing harmonics in both current and voltage inputs. This results in accurate measurements despite waveform distortions. The instruments feature many per-phase measurements for phase-balance assessment. The itronics TH models provide additional demand and harmonic measurements by digitally integrating instantaneous samples to obtain thermal demand and harmonic values. These demand values are used to record the minimum and maximum thermal demand values since last reset. TS (Modbus only) models also measure volts, frequency, and phase difference from two power sources for synchronizing applications.

3 Serial Transmission ptions educe wiring, terminations and input signal conditioning costs by transmitting the measurements to other digital devices using serial data communications. The family provides several serial options to interface with a wide variety of TUs, PLs, Ps, and other digital devices. The Modbus serial output option is a high-speed, high-capacity serial bus and protocol that is very suitable for real time distributed control and automation strategies. The S-485 bus is well suited for a medium speed multiple instrument monitoring system and has excellent noise immunity. The S-232 allows for short interconnection with a broad range of digital devices. The S-485 and the S-232 serial ports can be equipped with either Modbus TU or DP3 protocol. This provides for five combinations of serial ports and protocols that form network connections. Protocol hoices Modbus, certified by Schneider Electric, supports: 64 user selectable addresses; lobal Data, ead Holding egisters, and Preset Single/Multiple egisters for energy reset, demand reset, and scaling. Modbus TU Slave supports: 247 user selectable addresses; ead Holding egisters, and Preset Single/ Multiple egisters for energy reset, demand reset, and scaling. DP3 Slave supports: 256 user selectable addresses; ead by class, object or point; and Direct perate commands for energy reset, demand reset, and scaling. TH models include a configuration register to limit the class 0 response. PL Peer-to-Peer Serial Port Modbus, 9 pin D connector, 1Mbit/sec. Uses Modbus Protocol. S485 MDEM HMI nalog Transmissions ptions Transmit the itronics measurements to other devices using analog signals from a itronics nalog utput converter (). The communicates with the itronics serial port using Modbus TU or DP3 protocol over an S-485 bus, and then converts the register values to analog signals proportional to these measurements. Using a bus provides for several useful configurations. The S-485 bus allows for configurations with multiple instruments with cable runs up to 4000 feet (1200M). This distributed architecture also allows Hybrid configurations for use with mixed analog and serial solutions. nother useful feature of the distributed architecture is that the instruments can continue to be used, at no additional costs, when later upgrading to a serial communications network.
