One Channel SRWSS Receiver. The Short Range Wireless Switch System (SRWSS) is designed for short range (up to 1/2 mile) and simple wireless switching. The SRWSS is the simple solution for applications where faulty wire replacement or new installation of conduit is not possible or practical. The SRWSS (01245) consists of a one-input (12 VDC) transmitter and a one-output (SPDT Class C Relay) receiver. The SRWSS comes complete with power supplies and antennas. Simply make your connections, and the SRWSS is ready for use and guaranteed to perform. Turnkey, 12 VDC solar panel kits are available for locations without electricity. Possible Applications: Control: pumps, grain augers, conveyors, lights, valves & almost anything with a switch. Activate PLCs or for use in wireless automation. Radio Specifications: Frequency: 27.195 MHz FM, Bandwidth: 25 KHz at -20dB, FCC Part 15 compliant (no license required). Modes of Operation Relay contact rating: 5A @ 250 VAC Relay type: SPDT Class C Mode 1: Momentary (MOM) Mode 2: Flip Flop (FF) Mode 3: Latching-On (Off Delay 1-300 sec) Power Requirements: 12 VDC (power supply included), relay ON current: 45 mA, STBY current: 10 mA. SWRSS One Channel Receiver Contains: Relays with 5A @ 250 VAC Rating, NEMA 4X plastic enclosure, power supply, high-gain antenna, mount, and coaxial cable. Operation is Simple: The SRWSS is designed to be mounted to a wall or in another enclosure; the transmitter is triggered by supplying 12 VDC to the terminal blocks. This sends a coded set of instructions to the receiver. A two-position DIP switch allows the user to select from four modes of operation which control transmission duration. The receiver has several modes of operation. These modes determine how the output(s) function once a properly coded signal is received. A set of DIP switches located next to the microcontroller allows the user to select the mode of operation for the output(s).
