WHAT IS IT? The Model RSB is a heavy-duty safety control that provides a positive shut off of dangerous equipment in an emergency or for normal operation. A cable pulled by endangered personnel actuates it. The output contacts of the Model RS can control up to two separate circuits, one for machinery shutdown and one for an alarm. The Model RSB has the built-in advantage of cable break detection.
WHY IS IT NECESSARY? Safety minded operators of conveyors, production lines, elevator equipment, assembly lines, material handling systems, cranes, etc. consider it a must for employee protection. Most states have safety statutes that require these switches on conveyors and related equipment. American National Standard Institute recommends their use in ANSI standard No. ASME B20.1 - 1993-5.11. This ANSI standard will probably soon become part of the William-Steiger Act of 1970- the OSHA act.
