![]() If you need other IO features or additional IO, please contact Raveon sales personnel. Here is a summary of the standard IO features. The MODBUS protocol messages can be sent into the Tech Series radio over-the-air to set CLO output current. The Tech Series CLO version of the RV-M21 and RV-M22 series radio modems is ideal for SCADA and telemetry. Your SCADA PLC or MODBUS software can transmit a MODBUS message to the CLO radio to output the 4-20mA current you want sent out. Another Tech Series GPIO radio has 4-20mA input in it, and it sends the level information to the CLO radio.Ģ. The output currents can be sent over to this CLO radio in two ways:ġ. ![]() The Output Current coming out of this AIO interface has 2 4-20mA current outputs. The GPIO will mimic the sensor a long ways away to this modem with Current Loop Output ( CLO). On the GPIO radio, connect Sensors to Monitor. The Tech Series data radios have a myriad of IO terminal options, including CLO and GPIO. This CLO interface on the wireless link will send out 4-20mA signal that was measured miles away with the GPIO radio.
