PlantLinc^TM 5000 Industrial Wireless Serial Radio Modem for the 900 MHz ISM Band

PlantLinc^TM 5000 Industrial Wireless Serial Modem (model PLR5000) is an industrial serial RS232 radio modem designed for cost-effective, short-range PLC communications up to 4 miles. It operates in the license free 902-928 MHz band and uses frequency hopping transmission techniques for excellent reliability in noisy plant environments. It is a cost effective alternative to cable installation, trenching and leasing expensive phone lines to remote locations.

PlantLinc 5000 may be used for in-plant applications including PLC networking, data collection, mobile systems (cranes, conveyor systems, warehouse automation) and outdoor SCADA communications for remote pump stations and sub-stations. It supports all common serial protocols including DF1, Modbus ASCII, Modbus RTU, DNP 3.0 and Optimux with data rates up to 38.4 Kbps.

PlantLinc 5000 is field configurable and supports a number of operating modes including Master, Remote, Store-and-Forward Repeater and Remote/Repeater mode for added flexibility. It can accommodate most plant wireless projects using easy to install omni directional antennas or yagi antennas when a stronger signal is required.

PlantLinc 5000 is housed in a small, rugged, DIN rail mountable metal enclosure. It is rated for operation at -20 to +75°C (-4 to +167°F).

Industrial Applications

• Communications to PLCs on moving platforms

• In-plant SCADA network communications

• Remote pump stations/substations communications

• Maintenance of remote PLCs

• Factory floor for data collection
