Phillips & Temro Industries (PTI) has launched its new solid state relay controller (SSRC) for diesel engines. The PTI SSRC is an application-specific product which performs supervisory and diagnostic functions to safely switch high electric current and quickly protect against overload and short circuit conditions. Initial product applications include quick-start air intake heaters that require high current control and safety monitoring to provide faster start times on diesel engines, according to an announcement.
With no moving parts, the PTI SSR controller avoids mechanical-failure modes associated with traditional electromechanical relays, such as sticking, chatter or permanent welding of contacts. It also offers more desirable characteristics and design advantages, such as low power consumption, long life, small size, fast switching speeds, shock and vibration resistance, short circuit protection and diagnostic feedback, the company says. The PTI SSRC features controller area network (CAN) communications or discrete logic control depending on application requirements. The SSRC features electric current ratings up to 400A 12V or 200A 24V.
“The solid state relay controller was developed to replace mechanical relays in complex high current applications,” says PTI President Tom Moser. “Our OEM customers have brought forward a need for additional communication, control and safety specific to their unique applications not provided in past relays.”
PTI’s solid state relay controller has the potential for additional applications, including power gen and off-road, which the company is currently exploring.
