PlantLinc^TM 580D and 580DA Industrial Wireless I/O Extenders for the 900 MHz ISM Band

Data-Linc Group’s PlantLinc^TM 580 Wireless I/O Extenders offer the ability to economically transmit 4-20mA and discrete I/O signals without the cost or inconvenience of adding wires or additional devices. The PlantLinc 580 combines an analog/discrete signal digitizer with Data-Linc Group's short range PlantLinc industrial grade license free radio modem. The result is a cost effective, simple to implement wireless solution for I/O signal transmission up to 4 miles (6.5 km).

The PlantLinc PLR580D Wireless Discrete I/O Extender has eight discrete inputs and eight discrete outputs. The PlantLinc PLR580DA Wireless Discrete/Analog I/O Extender includes discrete signals plus eight analog inputs and eight analog outputs. The wireless extenders may be used in pairs for point-to-point signal transmission or in point-to-multipoint configurations, providing I/O signal transmission to multiple locations.

The PlantLinc RF section of the extenders operates in the license-free 902-928 MHz spread spectrum band and incorporates frequency hopping transmission techniques with 32-bit CRC error detection. The result is extremely reliable I/O communications even in high noise plant environments and at a range of up to 4 miles (6.5 km) with line-of-sight, using omni directional antennas. In the event of a communication link failure, discrete and analog outputs are software configurable.

PlantLinc 580 Wireless I/O Extenders are ideal for data acquisition and control applications such as tank level monitoring and pump control.
