SLT- Threaded Signal Line Protector
The Novaris SLT is a threaded signal line protector designed to be installed in a spare cablegland within a field instrument enclosure. These devices are designed with 10kA of common mode protection and MOV based transverse mode components. This combination provides an excellent level of protection in a very convenient form factor for signals up to 200V.
The SLT protection devices are available in 2, 3 and 4 wire variants, suitable for the appropriate process control transmitter signal configurations.
The SLT also supplies a shield connection wire which provides 2 functions:
- Ground Loop Isolation: Isolating the shield from the ground prevents current flow on the shield, reducing induced noise onto signal pairs.
- Equipment Bonding: During a surge the Gas Discharge Tube will fire, bonding the earths of the two sites together through the larger shield conductor. This reduces the earth potential difference between the sites.
The SLT is available with enclosures designed for M20 x 1.5 and ½” NPT glands.
