PROCESS CONTROL RO-4 Radio Frequency (RF) Receiver with Four Universal Outputs duplicates point information received from up to four different transmitters. Each of the output points may be individually configured for an SPDT contact output or an analog output of 0-20 mA or 0-10 VDC. There is no RF tuning, no external RF antenna, and no specific radio experience required to install or use the system. The RF signal uses proven spread-spectrum technology, and has an open-air range of 2700' (823m).
