The SZL-VL-S-G is a safety control system from Honeywell that is used to control an electrical contactor's start and stop function in hazardous and non-hazardous locations. The system includes a VL-S-G relay, which can control a contactor from an external source, such as a push button, as well as from a direct voltage source. It includes two programmable logic outputs that can be used to provide indication, control, or alarm functions. The system also features a self-confirming dual lock safety contactor that provides safe switching and, when the voltage is removed, it will return the contactor to its default position. The SZL-VL-S-G system is certified to UL and CSA standards, and is backed by a five-year limited warranty.
