Description
The FS500 Series flash rate is adjustable from 10 to 100 FPM. A locknut is provided to hold selected flash rate. The long-life electronic circuit combined with a quality electromechanical relay provides flexibility and reliability in most applications. Operation Upon application of input voltage, the output relay is energized and the ON time begins. At the end of the ON time, the output relay de-energizes and the OFF time begins. At the end of the OFF time, the output is energized and the cycle repeats as long as input voltage is applied. Reset: Removing input voltage resets the output and the sequence. Features & Benefits FEATURES BENEFITS Solid-state circuitry with electromechanical relay Long life circuitry at a reliable low cost Industry standard octal plug connection Eliminates need for special connectors Adjustable flash rate Provides flexibility for user to select flash rate between 10 - 100 FPM 10A, DPDT isolated output contacts Allows control of loads for AC or DC voltages Accessories BZ1 Front Panel Mount Kit Provides an easy method of through-the-panel mounting of 8- or 11-pin plug-in timers, flashers, and other controls. NDS-8 Octal 8-pin Socket 8-pin 35mm DIN rail or surface mount. Surface mounted with two #6 screws or snaps onto a 35 mm DIN rail. Uses PSC8 hold-down clips. PSC8 Hold-down Clips Securely mounts plug-in controls in any position. Provides protection against vibration. Use with NDS-8 Octal Socket. Sold in pairs. C103PM (AL) DIN Rail 35 mm aluminum DIN rail available in a 36 in. (91 .4 cm) length. L1 N/L2 V = Voltage
