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) away.

The PlantLinc 580D Wireless Discrete I/O Extender (model PLR580D) has eight discrete inputs and eight discrete outputs. The PlantLinc 580DA Wireless Discrete/Analog I/O Extender (model PLR580DA) 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 radio 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 outputs will default to open, while analog outputs will default to 4mA.

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

Industrial Applications

• Field and factory floor discrete and analog signal communication for all industries

• Wireless connection between instruments or controllers/relays and PLC or RTU analog/discrete input and output blocks

• Water/Wastewater example - monitor tank levels with 4-20 mA analog signals and control pumps with contact closure discrete signals.
