DESCRIPTION
The SW-100 accepts a frequency input, and controls a single relay (SPDT) based on the value of the input frequency. The Trip frequency can be set to any value from 0.1 Hz to 25 KHz. The SW-100 can be set to trip on overspeed, or underspeed (including zero speed). Offset and hysteresis values can be incorporated into the trip setting to eliminate output chatter. LED indicators for both the Input signal and the Relay status are provided. Two separate input connections for external push-buttons are also provided. One external input overrides the trip detection function, and holds the relay in the release state as long as the input is pulled to common. The other external input clears a latched trip condition when pulled to common.
The SW-100 utilizes a seven position DIP switch, a rotary switch, a push­button and two indication LEDs to accomplish input circuit configuration, operational parameter set-up, input signal, and relay status indication. The input circuitry is DIP switch selectable for a variety of sources.
The indication LEDs are used during normal operation to display the input signal and relay status of the SW-100. These LEDs are also used to provide visual feedback to the user of the current parameter settings during parameter set-up.
DIMENSIONS In inches (mm)
The SW-100 operates in one of six output modes, as selected by the user. The programmable Minimum Response Time provides optimum response vs. input filtering for any input frequency. The offset and hysteresis settings provide flexible adjustment of the relay trip and release points.
The unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails, including top hat profile rail according to EN 50 022 - 35 x 7.5 and 35 x 15, and G profile rail according to EN 50 035 - G32.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
WARNING: SPEED SWITCHES MUST NEVER BE USED AS
PRIMARY PROTECTION AGAINST HAZARDOUS OPERATING
CONDITIONS. Machinery must first be made safe by inherent design, or the installation of guards, shields, or other devices to protect personnel in the event of a hazardous machine speed condition. The speed switch may be installed to help prevent the machine from entering the unsafe speed.

Notes:
1. This device was designed for installation in an enclosure. To avoid electrostatic discharge, precautions should be taken when the device is mounted outside an enclosure. When working in an enclosure (ex. making adjustments, setting switches, etc.) typical anti-static precautions should be observed before touching the unit.
2. For operation without loss of performance: Unit is mounted on a rail in a metal enclosure (Buckeye SM7013-0 or
equivalent) and I/O cables are routed in metal conduit connected to earth ground.
Refer to the EMC Installation Guidelines section of this bulletin for
additional information.
