YodalightEx YO4IS — Intrinsically Safe Sounder
The Yodal EX YO4IS is an intrinsically safe audible signal designed for hazardous environments, delivering up to 100dB at 1 metre with 32 selectable tones and a two-stage alarm for reliable room or zone coverage. Built in flame-retardant ABS with stainless-steel fixings and a monitoring facility, it is rated for explosive atmospheres.
Like all YodalightEx IS products it must be powered via an approved Zener Barrier or Galvanic Isolator; powering it directly will damage the unit and void protection.
Reliable, certified sounder output for explosive-atmosphere process control.
IMPORTANT! This product must be used with an approved Zener Barrier or Galvanic Isolator. All connections into the product must be made via a suitably rated barrier or isolator — never connect it directly to the voltage supply without a barrier in place, as this will cause permanent damage to the PCB and void the warranty. Installation and connection should only be carried out by appropriately competent and qualified personnel.
Typical applications: oil and gas, petrochemical, chemical plants, offshore, hazardous-area process control.
