More Info:

The RCI-100-FSK is a bi-directional remote communication system that exchanges the status of 1 dry contact input and 1 analog input between a master and remote unit. Both the master and remote unit have inputs and outputs to allow remote monitoring and remote control.

Since the master and remote units are connected via leased telephone line, and hence are ‘always-on’, a change in signal at one end is transmitted to the other end with very little delay. This makes this unit ideal for real-time monitoring of remote tanks, pumps, etc.

The bi-directional operation allows for control signals to be sent back to the remote site to take action based on the incoming monitored signal.
This unit may also be used as a remote unit in a multi-remote system where the master is a multi-channel device such as the RCI-200-FSK, RCI-400-FSK or RCI-800-FSK.

Set Up

…I speak of you often because I have always been impressed with being able to get immediate attention from you. I tell folks that not only do I get help; it’s the only business I call where I speak with the President of the company!…I appreciate your personal attention in this age of “press 1, or press 2”. Add that to your “bulletproof” product, and you are my definition of a” world class company”. Keep up the great work. Thank you
