Remote Data Acquisition

Remote Data Acquisition

ADVANCED CONNECTIVITY OPTIONS

Sometimes your sensors or the piece of equipment you are trying to control is not in a convenient place to have a PC close by. The sensors may be widely distributed through out your plant and it just wouldn’t be cost effective to run all your wiring to where the PC is. In addition, low level signals are more accurately acquired when digitized close to the signal source. In all these cases our REMOTE ACCES line of products will help. The REMOTE ACCES pods are intelligent, sensor to computer interfaces. Each pod can be used as an autonomous data logger to acquire data for later download. Or as many as 31 pods may be connected on a single two wire multidrop RS-485 network allowing a cable distance of up to 4000 ft. You can also go wireless and extend your range by adding RS-485 wireless transceivers to your serial port. Each unit comes in a rugged NEMA 4 enclosure and can withstand harsh industrial and marine environments.

All of our remote products share many features, including an integral microcontroller software programmable baud-rate, software-upgradeable firmware, EEPROM for configuration storage, optically-isolated RS485 serial operation at up to 28.8K baud, (non-isolated option at 57.6K baud) and availability in NEMA 4 sealed enclosures.

WM – includes a Wireless transceiver set. On the computer side, the Wireless module is powered by a wall adapter and plugs directly into an RS-232 port. These can be configured in a number of ways including 900MHz or 2.4GHz models. It includes a wire antenna, and no software is needed, thus making the Wireless link transparent to the user. On the Remote side, the unit has a Wireless transceiver installed in the lid of the protective metal enclosure which is then wired into the I/O Pod. One AC/DC supply is included with this which plugs into 115VAC and powers all the electronics of the I/O and the Wireless module. The unit ships with a power cable and DB9 connector to plug into the DC output of the supply. Alternately, if no AC power is available at the remote site, a battery can be purchased instead of the AC/DC supply. The Wireless version is handy for systems where you need to add a remote alarm or pick up a contact closure at some distance from a PC, without running any wires. Different ranges are possible with different antennas, from a couple-hundred feet up to 22 miles with a clear line of site. A Spread-Spectrum un-licensed radio set is used with a frequency hopping feature for higher reliability.

USB
U – is packaged for connection to a USB port. This solution uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the board. Communications with the host computer are accomplished via our USB-485 converter to a cable wired up to the serial data screw terminals on the board.

STANDARD RS-232
S – is packaged for connection to an RS-232 port via an RS-232 to RS-485 converter. This solution also uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the board.

ETHERNET
E – is packaged for connection to a Ethernet port. This solution uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the board. Communications with the host computer are accomplished via our ethernet to 485 module wired directly to the serial data screw terminals on the board.

RAD242These cards are 24-bit parallel, digital input/output cards designed for use in PCI-Bus computers. The difference between the models is that I/O connections to PCI-DIO24D are via a standard 37-pin D-sub connector while I/O connections to PCI-DIO24H are via a 50-pin connector. The cards are 4.80 inches long (122 mm) and may be installed in any 5V PCI-bus slot in IBM and compatible personal computers.Learn More
