The TP232 RS-232 Serial Surge Protector is a robust, multi-stage surge suppression solution engineered to protect serial communication lines from high-energy transients. Suitable for use in industrial and commercial environments, the TP232 is safe for PLCs, computers, weighing indicators, printers, and other devices that rely on RS-232 or similar protocols.
Its three layers of protection—a gas discharge tube, series resistor, and transient voltage suppressor (TVS)—work together to guard connected equipment against harmful spikes and voltage surges. This setup ensures both low clamping voltage and fast response time, critical for preserving signal integrity in serial communication lines.
With five-position terminal blocks, the TP232 offers simple wiring for essential serial signals like transmit, receive, RTS, CTS, and signal ground. The device is housed in a durable enclosure with dual ground terminals and includes two mounting brackets for quick installation near critical equipment.
