Production introduction:
TRSS-DB9 and TRS-DB25 surge protector are designed to protect sensitive equipment linked to datalines equipped with D-sub connectors, as RS232, RS422 and RS485lines. They are equipped with D-sub connectors for fast and easy maintenance. In order to comply with the line configuration, all the wires are transmitted and protected.
Product Feactures:
1. D-Sub surge protector
2. For RS422 communication lines
3. 9-pin connector
4. Fast and easy installation
5. Secondary protection
