Product Descriptions
The SF Series switch followers are a two way system designed to provide a quick
and cost effective solution for a variety of wireless switching applications. Each
unit has four inputs connected to a transmitter and four 10 Amp SPDT relay
outputs connected to a receiver. Designed to work in pairs, the output relay at
the
receive
end of one unit will “follow” the input at the
transmit
end of the other
unit.
An optional
loopback
mode can be set for each channel separately. This will
activate the corresponding relay at the originating (TRANSMIT) end confirming
the switch change was carried out at the other unit. The inputs on the other unit
are ignored for those channels set in the loopback mode.
The 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.
Alternatively, instead of automatic switch following operation, the SF900 can
operate as a 4-channel wireless relay using a SFT900-4 4-button handheld
remote control. In this configuration, latched, momentary and toggle mode
outputs are available. When a button is pushed on the SFT900-4, a beep will
indicate that the proper relay was triggered in the SF900. In this configuration,
the SF900 is always in the loopback mode.
These products utilize frequency hopping spread spectrum technology and are
immune to interference and multipath fading. All inputs and outputs are
independently isolated from each other and from the power supply and ground.
Expected range with these products is 1 mile*. The receiver requires 12 to 24
Volts AC or DC (supply not included).
* Unobstructed, straight line-of-sight range, when used with the standard antennas
included with the units.
