Omron has introduced a range of industrial high-power solid state relays (SSRs) that offers extended life and greater reliability thanks to a unique surge pass circuit. Omron’s SSRs are often required for heating control in industrial processes where products require drying or baking, for example within the food and beverage industry and also in the production process of flat-panel display equipment in the semiconductor industry. In such instances, furnaces and ovens are heated electrically using high currents passed through Ni-Cr alloy wire elements, or by halogen lamps.
Impervious to power surges
SSRs are known to be susceptible to (power device) damage in the event of high surge noise. As continuity is vital for productivity, Omron has made available an SSR which is able to handle surge noise. The new G3PH industrial high-power solid state relay offers superior resistance to surge voltages thanks to an original surge-pass circuit that gives the G3PH outstanding endurance and protects it against surge voltages in excess of 30 kV.
Cost effective solution
The non-zero-cross version of the G3PH, in combination with the Omron EJ1 modular temperature controller and the G3ZA multichannel power controller, offers a cost effective solution compared to the more expensive option of using a standard power controller. The G3PH series also offers other benefits, including replaceable power device cartridges for ease of maintenance, zero-cross load switching, built-in heatsinks and operational indication. It conforms to all current safety standards, including CE, cULus, and TUV.

IT in Manufacturing
Ten years ago, I was quite proud of how smart the machines in our factory were. Now, with my current definition of smart, I realise they were quite stupid. Why? Because although they were doing what they were designed to do, the minute they encountered anything unexpected or out of the ordinary, they were stumped.
