Eurotherm Zelio Solid State Relays
Thermal Devices is an authorized Distributor of Eurotherm Controls' Zelio products and carries the full line of Zelio solid state relays. Solid State Relays have been the standard in switching technology since the early 70's due to their high switching frequency, resistance to shock and vibration and superior lifetime. All Continental Industries and Eurotherm solid state relays are now obsolete and can be replaced by Eurotherm's Zelio solid state relays.

Features of the Eurotherm Zelio solid state relays:
Long Life Reliability
When properly used, a Solid State Relay (SSR) provides a high degree of reliability, long life and reduced electromagnetic interference (EMI), together with fast response and high vibration resistance, as compared to an electromechanical relay (EMR).
Fast Switching
Solid state relays can switch up to 120 times per second, much faster than any electromechanical relay. When used in heating applications, fast cycling can dramatically improve the life of the heater by reducing thermal stress.
Low Input Power Required
SSRs allow the switching of large loads via ultra-sensitive input power. A low level logic signal (TTL) can activate a switch for as much as 125 Amps.
Quiet Operation
Completely quiet switching, beneficial in medical applications, environmental controls or other areas where quiet operation is desirable. Zero-crossing control also means low electrical noise when used near computers, PLC™s, SCADA systems, or other factory automation control systems.
Relay Packaging
Eurotherm by Schneider-Electric is an industry leader in product innovation. We were the first company in the U.S. to produce and market a fully integrated DIN Rail mountable solid state relay with heat sink. We have proven that leadership again with the introduction of the Zelio family of SSRs.
