B+B SmartWorx RS-232 High Energy Surge Protector - Terminal Block
The Model 232HESP is designed to help protect against lightning strikes, power surges, and other types of voltage disturbances. Five RS-232 signals on terminal blocks are supported with a clamping voltage of approximately 15 volts. The 232HESP offers three stages of protection starting with a gas discharge tube followed by a series resistor and finally a Transient Voltage Suppresser (TVS). In order for a surge protector to work properly it is important to have a good connection to earth ground. The 232HESP offers two terminal posts and two metal mounting brackets that provide a good ground connection for the user. The 232HESP has been tested to two specifications at 6 kilovolts, IEC 1000-4-5: 1995 "Surge Immunity Test" and IEEE C62.41-1991 "IEEE Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits". To ensure the best protection of your equipment some simple connection guidelines should be followed.

B&B PORT POW 4KV 232 OPTO ISO
Optical RS-232 isolators to suit almost any application
Our RS-232 optical isolators are ideally suited for many applications - from "control panel" installations requiring DIN Rail mounting to "in-line" or "bump in the cable" installations found in laboratory or retail systems. They provide 2 kV of isolation to protect your equipment as well as a variety of connector options. If you require extended temperature ranges and extra rugged construction, our industrial products will fit the bill. They have advanced EMC and emissions specifications that run the gamut from light industrial EN 61000-6-1 to heavy industrial EN 61000-6-2 with IEEE 1613. We also offer versions with UL 508 and UL Class 1 Division 2. Check out the specs on each product and select the optical isolator that is best suited for your needs. Learn More$140.83 -
