4-20 mA Signals Repeater RAL-3500
Between local and remote stations via radio
Up to 20 signals 4-20 mA in any direction

The RAL-3500 Systems are based on wireless devices destined to retransmit (recopy) remote mV or mA signals by radio in the ISM unlicensed 868 MHz band with transmission power up to 500 mW.
Appropriate to reproduce mA current loops and logic signals in a remote system, from the corresponding inputs in a local system.

Analog signal repeaters via radio without PC
A mA signal variation in one input of the local modules is reproduced exactly in a mA output of the remote modules
25 mW, 100 mW or 500 mW transmission power
SMA connector for external antenna
Up to 10 km under appropriated conditions
Anticross system for several devices in the area
Standard version from 2 up to 20 signals total
Version to retransmit signals in both directions
Enclosure in DIN rail mounting or optional enclosure IP65 for field mounting
Power supply 85...265 Vac or 12 / 24 Vdc (option) 868 Mhz
