Videographic paperless recorder ElMetro-ViER-104K
Videographic paperless recorder ElMetro-ViER-104K (10.4”) is intended for measurement, record, visualization and conversion of electric signals of sensors and instruments: current and DC voltage, resistance, resistance thermometers, thermal couples, pyrometers, digital signals (RS-485, CAN, Ethernet) as well as calculation of mediums flow. Recorder is designed as a switchboard device, it is equipped with a display and touch-sensitive keyboard (capacitive type). There are general purpose industrial and Ex-proved ([Exia] IIC) types of the recorder. All inputs of Ex-proved type are of intrinsically safe electric circuit with [Exia] IIC marking.
Recorders ElMetro-ViER-104K are designed to replace paper chart recorders and could serve systems for data collection and transmission to control system as they are equipped with RS-485 (Modbus RTU), CAN 1.0/2.0 and Ethernet (Modbus TCP) interfaces. Recorders ElMetro-ViER-104K accomplish functions of regulation, signaling and mathematical processing of measured parameters. Measured parameters could be represented as trends, scales, numerals, trends + scales, dials and mnemonic schemes with a wide range of display settings.
Using mnemonic schemes of the technological process makes understanding of information easier, especially in emergency situations at the site. A liquid crystal display with sensitive keyboard simplifies recorder configuration and control. It is possible to design distributed data collection and data logging systems on the basis of recorder ElMetro-ViER-104K with the usage of input-output modules ElMetro-IOM. Recorders could be applied almost in all industries, including at consignment and hazardous manufacturing:
- Metallurgy – multichannel types (control of large quantity of parameters), vandal-proof construction (front panel is protected by 5 mm tempered glass);
- Energy and machine-building industry – 1 or 2-channel types (installation at operational loop, rolling lines and etc.);
- Petroleum, chemical and gas production – Ex-proved type.
Due to advanced mathematical and logical capabilities recorders could fulfill functions of industrial controllers. They could also be used as flow rate calculators according to the pressure drops or gas correctors in accordance to GOST 8.586.(1-5)-2005.
Technical characteristics:
ElMetro-ViER-104K recorder is designed in metal housing with 264 mm (10.4”) diagonal TFT-display in the front panel and resolution of 800х600 pixels. Display is equipped with LED backlight. Front panel is fully covered by 5 mm tempered glass which ensures display protection from mechanical damages as well as dust and moisture. Keyboard is touch-sensitive (capacitive type), pressing a button is accompanied by diode emitting above it. Multichannel recorders has a slot construction (slot is a plug connection for a board installation). There are 6 input/output slots where different boards could be installed (boards of analog inputs, boards of current outputs and etc.), type and number of boards are defined at ordering. Central processor of the recorder collects data of all analog, discrete and pulse-frequency inputs and initiates commands to control current outputs and output relays. Processed information is stored in internal non-volatile memory and is output to the display. Recorder construction excludes possibility of a switch usage. Each analog input has its own ADC. In such way data from all channels is collected in parallel, in other words all channels are polled simultaneously. As a result a higher reliability and high-speed response could be reached – measurement cycle of all channels makes only 0.1 s. Built-in interfaces enable data interchange between the recorder and PC or other devices with relative interfaces.
Recorders ElMetro-ViER-104K are divided into three types:
- General purpose industrial type (multichannel);
- 1 or 2-channel general purpose industrial type;
- Ex-proved (ViER-104К-Ex) - with [Exia] IIC Ex-proof marking.
According to a task, recorders could have different number of inputs/outputs. Dependence of inputs/outputs number on the recorder type is provided in the table below:
Recorder type Number of inputs/outputs (analog, discrete) A input A output D input D output general purpose industrial up to 20 up to 8 up to 32 up to 32 general purpose industrial 1 or 2 channels 1 or 2 1 or 2 0 4 or 8 Ex-proved up to 10 none up to 16 up to 16 Maximum number of mathematical channels is up to 64.
Maximum number of analog channels could be extended to 32 if external input/output modules ElMetro-IOM or ElMetro-IOM-02-Ex are connected.
In order to provide power supply of connected sensors supply package of the recorder may include a single-channel power supply (based on 1AI-1AO-1PS) with following parameters:
- Output voltage – (24±2) V;
- Maximum output current– 25 mA;
- Built-in protection from short circuit and overload;
- Isolation voltage – 1500 V (rms value) to power input ~220 V;
- Protection from short circuit and overload at output.
or 4-channel power supply with following parameters:
- 4 isolated outputs of power supply Uout = (24.0 ± 2.4) V;
- Output current – not less than 100 mA per a channel;
- Output ripple voltage amplitude – not more than 50 mV;
- Isolation strength – 1500 V (rms value) to power input ~220 V;
- Control (indication and record) of short circuit or overload at output;
- Protection from short circuit and overload at output.
Board of power supply 4PS could power up to 16 sensors, which are connected to the recorder, from current loop 4-20 mA. Board of power supply PS is an independent power supply which works separately from analog inputs with sensors power channels AP and AIP.
