For applications where the price of the system is crucial ED has developed family of digital temperature and humidity HYT sensors with economical price but quality and accuracy of much more expensive devices.
 

HYT sensors can make network of 127 devices. The connection is made with economical telephone cable. Network can end with USB to RS485 adapter plugged into a standard PC.

 

 

 

When connecting measurment system to an outside source, there is always a risk of ground loop or overvoltage. Signal conditioners and transmitters with galvanic isolation of 1500Vrms (4kV for 1 minute) can prevent these risks.
 

Input signal is filtered, level-adjusted, linearized, isolated and converted to voltage or current sutable for data acquisition system, or any other measurment device.

Tipical accuracy is 0,03%, with 0,01% linearity. There are models with voltage, current, RTD, thermocouples, potenciometers, measurment bridge, RMS to DC, transmitter and other inputs. Special ranges can be ordered on customer demand.

About signal conditioners and transmitters

VTS is industrial, digital, temperature and relative humidity sensor. One modbus controller can connect to up to 247 VTS sensors. With USB-485 adapters 247 VTS sensors can be connect to each USB port on a standard PC computer. Electronic Design recomends using A7 industrial computer with VTS sensors. VTS sensors can be optionaly made with analogue 4-20mA outputs on customer request.

 

VTS sensors are designed for pharmaceutical and food manufacturers and storage facilities. They can be used in freezers, cold rooms, clean rooms, hospitals, hot chambers and other facilities. VTS can work in temperatures from -40C to +85C, and relative humidity from 0 to 100% (non condensing). Accuracy is better then 0,5C in range from -10C to +50C (0.3C at 25C). Relative humidity accuracy is better then 3% in range from 20% to 80% rH. Resolution is 0.1C or 0.1% rH.

VTL is a miniature, precise, batery operated temperature and relative humidity logger. It's used for cold chain temperature and humidity tracking during transport, storage space mapping, in production and storage of food and drugs, and for many other applications.

 

 

Measuring range for humidity is from 0 to 100%, and for temperature from -20 to +60C. VTL hal very low power consumtion and typical battery life of 7 years. Collected data is transfered to a PC using standard USB mini cable, using free software. Data can be printed or saved to XLS file.

  

RS-485 is one of the most popular comunication standard in the industries. Many protocols like modbus, profibus, Interbus, Optomux Data Highway, Measurment Bus, P-Net and others, use RS-485 as hardware base for comunication. When RS-485 is used with computer or PLC, protocols can be easily implemented through software. All you need is RS-485 adapter for standard computer perifery like RS-232 or USB.

 

ISO-485/422 is a proffesional, industrial, opticaly isolated serial adapter that converts RS-232 to semi-duplex RS-485 or full-duplex RS-422. ISO-485/422 is ideal for heavy industrial applications. No programming is required. Transmition rate from 150 to 115200 bit/s.Maximum range up to 11km, depending on other devices used, cable properties and baud rate.

PLC is good. Industrial PC is BETTER!
 

 

A7, is new, inovative design that integrates advanced technological solutions. It is using low power INTEL processors to work without fans, and in fact, without any moving parts, so it is quite suitable for aplications where machanical motion or vibrations can damage other computers.

 

A7 is the smallest (115 x 99 x 25 mm) compleatly functional industrial PC, specially designed for DIN rail mounting.

 

A7 is designed in PLC manor, but it is fully PC compatibile system with much higher processing power. It has USB 2.0 and 3.0 ports, isolated RS-232 and RS-485 ports, gigabit LAN and SSD. User can install any PC operating system, and use standard PC programing for A7 system.

 

A7 works with ATOM processors. It uses natural air convection for cooling, and SSD for storage, so there are no moving parts. This drasticaly increases reliability of the processor module.

 

 

 

A2 industrial PC can improve your existing IT infrastructure and connect it with physical processes in production, storage and power supply. This can increase economy, productivity and performances of any industrial facility.
 
            
Based on compatibility with open PC standard,
A2 allows for easy integration with hardware and software into an existing network, using familiar operating system, comunication protocols and existing knowlege using PC systems.

 A2 has analogue and digital I/O modules for data acquisition, measurment and process control. It's using powerfull PC processors and large amount of RAM and disk space. Models without moving parts are available on customer request.

AC/DC switching power supplies of CS series are designed to supply devices with stable voltage of 5, 12, 24 or 48V DC. CS are designed for use on a DIN rail, and they can work with T-BUS connectors, over a DIN rail, in order to reduce the number of wires used. T-BUS connectors can be used with CA, ISO-485/422, A7 and many other devices. Available are power supplies with 48W and 90W output. Input can range from 85V to 265V AC, or from 100V to 400V DC.
 

 

USB-485 converter is optically isolated (1.5kV rms continuous or 4kV rms for 1 minute) adapter which converts USB to RS-485 semi-duplex comunication. It can work on baud rates from 150bps to 500kbps. It can operate on cable range up to 11km (depending on other RS-485 devices used, cable properties and baud rate). Protection against overvoltage and transients.
