DIN-rail data line surge protector
Citel's data line surge protector model DL180 is DIN-rail mountable with a compact design that makes it suitable for applications with space limitations. I/O connections are made with screw terminals. It uses a multistage circuitry that automatically resets after every surge. Citel DL180 protects against lightning surges and electrical transients in 4-20mA loops, phone lines, RS232, RS422, RS423, RS485, and 50mA current loops.
