Relay control panel was originally intended for the Board of Education for New York City specifications for operating DC solenoid valve to control gas flow for home cooking classes, school kitchens, metal, and ceramic shops. Due to its numerous features as well as silent operations, the panel is used in numerous other related institutions as well as Schools outside the city of New York. Malicious mischief and vandalism have caused a few cities Governments for making it mandatory, which gas supply, become secured during the hours when schools are clogged. Other consulting engineers and governmental bodies have also accepted this requirement and identify when not authorized by the code. Relay can also be utilized in the industrial as well as commercial installations whereas control of different fluids and gases are significant.
Operations
Operating key switches for panel control station boosts relay, opening the normally closed DC solenoid valve that turns on gas flow.
Panel Features
Reliability
Longer experience with control makes sure the highly reliable system particularly when utilized in the combination with the valves. In case, relay is lost totally, or reduces for approximately 50% for normal value, spread de-energizes usually closed valve for shutting off gas flow. Gas can also become shut off through depressing usually closed switch located on control station. This valve cannot open the voltage restoration of pending the authorized person operating key switch for control station. It eliminates risk of gas mistakenly escaping. For the expediency, auxiliary push-buttons can be situated at different access points all the way through the building of instant shutoff under the emergency conditions.
Silent Operation
Utilization for DC output given by relay for valves eliminates the constant AC drone.
Appearance
Shallow depth NEMA flush increased enclosure allows installation directly to the wall of convenience, as well as elimination of the obstructions with corridors or the highly traffic areas.
Long Life
The dust-tight industrial impart as well as solid condition rectifier are specially designed for providing longer life.
Easy Installation
Clearly marked installation drawings as well as terminals are positioned on the door inside.
Approvals
Originally designed as well as approved for the use in related fields.
Relay Control Panel (AC)
Relay offers same features like DC panels before described, apart from with the AC voltage production of the AC valves. Relay features the key-operated switch with the manual on/off buttons straight on cover. It is for the flush mounted applications as well as supports the surface mounted installations. It is also accessible with different outputs.
Master Controlling Stations
Relay consists of the key-operated, usually-open switched as well as normally-closed button increased in the faceplate of stainless steel of flush installation. The switches are tagged "Open" over key switching as well as "Shut" over button.
Control Stations
Relay consists of the momentary mushroom button known as "Emergency Stop". While button is dejected Power to the valves is off, cut off the gas flow with below 0.1 seconds.
