The SFA900C Analog Sensor, Remote Control/Switch Followers are a system designed to provide a quick and cost effective solution for a variety of wireless switching and remote sensing applications. Each transmitter has 4-Analog inputs, 4-Digital inputs and 4-Relay outputs. Each receiver has 4-Analog outputs, 4-Relay outputs and 4-Digital inputs.
The universal Analog inputs are default 0-10 VDC but can be jumper selected for for 10k thermistors or 4-20mA inputs. The analog outputs are set up for both 4-20mA and 0-10 VDC on separate terminals. Custom versions are available to accommodate other analog inputs and outputs, as well as two-way communication.
The Digital inputs are opto-isolated and may be operated by an applied voltage that can be supplied by a power source from 5 to 24 Volts AC or DC through a switch contact, relay, sensor, PLC output, etc. The digital outputs are isolated relay contacts.
These products utilize spread spectrum technology and are immune to interference and multipath fading. These systems will not interfere with wifi networks.
