Product catalog summary

Introduction
CIRCUTOR provides a range of programmable digital indicators and instruments for displaying electrical parameters and setting up alarm systems. These digital instruments offer numerical information with higher accuracy and reliability than analogue instruments, featuring advanced input capabilities like higher input impedance and automatic scale selection.

Product Selection
The document categorizes digital instruments and transducers by series, such as DC, DH, Royal, DM45, and CMM 96, each designed for specific applications including single-phase and three-phase measurements.

Specifications and Features
Digital instruments are available in various sizes and are multi-scale programmable. They measure true root mean square (TRMS) values for voltage and current with high accuracy and resolution up to 16 bits. They support module connections including relays, analogue outputs, and PC communications via RS-232 and RS-485 with MODBUS RTU and ETHERNET protocols, and are compatible with PowerStudio software for data centralization and recording.

Applications
These instruments are used for displaying numerical values of electrical parameters, setting up alarm systems, and controlling processes via software, managing voltage, current, frequency, temperature, harmonics, and time control.

Series Details
DC Series: Digital indicators for panel mounting with programmable scales, TRMS measurement, and optional relay outputs, designed for measuring voltage, current, frequency, and temperature with high accuracy and a 4-digit display.
DH Series: Designed for panel mounting, displaying programmed values of electrical variables or process signals, offering high luminosity displays, true RMS measurement, and multiple expansion module options.

Transducers
The document covers narrow profile and high-precision transducers for single-phase and three-phase applications, emphasizing their accuracy and industrial application.

Standards and Compliance
All instruments and transducers comply with current regulations and standards, ensuring high protection degrees and reliability in measurement processes.

Communication Specifications
Communication speeds range from 1,200 to 19,200 bits/s with parity options and stop bits selection. RS-232 and RS-485 modules offer EDS protection and thermal protection, adhering to EIA standards.

Relay and Analogue Output Features
Relays are available in 2 or 4 configurations with specific nominal current and voltage standards. Analogue outputs have a resolution of 14 bits with insulation standards.

Digital Instruments and Measuring Transducers
M2 series offers optional output programming and programmable output range, with high luminosity displays and TRMS measurement for single and three-phase systems.

Converters
Convert voltage, current, or frequency in single-phase systems, with high-precision transducers for industrial environments.

Overview
The document provides technical specifications and ordering information for digital instruments and measuring transducers, detailing input types, measurement accuracy, and coding for non-standard orders.

Specifications
Auxiliary Power Supply: Standard is 230 Vac, 40...90 Hz. Non-standard orders require specification of code, input range, output range, and auxiliary power supply.
Measurement Accuracy: Generally ±0.2% reading for most transducers, with exceptions like active power and power factor transducers at ±0.5%.

Transducer Types
Includes various transducers for DC voltage, leakage current, frequency, galvanic insulation, temperature, resistance, active power, reactive energy, power factor, Cos j, and current distortion factor, each with specific codes.

Ordering Information
For non-standard orders, specify code, input range, output range, auxiliary power supply, and additional parameters as per the coding table.

Coding Table
Provides internal codes for various input and output standards, including voltage, current, resistance, temperature, and frequency.

Accessories
Includes software like PowerStudio and various front panel adaptors with specific codes for different sizes.
