The Rice Lake TP232 RS-232 Serial Surge Protector is a high-performance surge suppression device designed to protect serial communication equipment from damaging voltage spikes, transient surges, lightning-induced disturbances, and electrical noise. Engineered for industrial weighing systems, automation controls, data communication networks, and process control applications, the TP232 helps ensure reliable operation of critical equipment while reducing costly downtime and repairs. It features a proven three-stage protection system consisting of a gas discharge tube, series resistor, and transient voltage suppressor (TVS), providing layered defense against high-energy surge events.
Designed for use with RS-232 communication lines, the TP232 protects transmit, receive, request-to-send (RTS), clear-to-send (CTS), and signal ground circuits through dedicated terminal block connections. The unit is safe for use with computers, PLCs, printers, remote displays, indicators, and other industrial communication devices. In addition to RS-232 applications, the TP232 can also be used with RS-485, RS-422, and 20 mA communication systems, making it a versatile protection solution for a wide range of industrial environments.
The surge protector incorporates two grounding terminal posts and includes metal mounting brackets to facilitate proper installation and grounding. Effective grounding is critical for surge protection performance, allowing transient energy to be safely diverted away from sensitive electronic equipment. Its compact housing enables installation within control panels, instrumentation cabinets, or equipment enclosures without consuming excessive space.
With rapid response characteristics and industrial-grade construction, the TP232 helps safeguard communication equipment from power disturbances commonly found in manufacturing facilities, warehouses, processing plants, transportation systems, and industrial automation environments. Whether protecting a weighing indicator, industrial printer, PLC, or remote display network, the TP232 provides dependable protection that helps extend equipment life and improve system reliability.
