Surge protection with filter function for a 2-wire floating signal circuit, e.g., 0(4) ... 20 mA current loop, HART-compatible.
EMC filters limit high-frequency interference voltages and currents generated by equipment during normal operation and occurring under fault conditions. Using our EMC filters, you ensure smooth operation in environments subject to interference.More information
FIL provides effective protection against high-frequency interference. Additional PE terminal points improve the filtering effect in the event of high-frequency interference between the active conductors and the ground potential for filters in plastic housings.
The new, universally applicable TTC-6-SFP... interference suppression filter limits and filters high-frequency interference on signal lines. In addition, overvoltages are safely discharged.
Frequency converters, switching power supplies, and lighting system drivers are often sources of interference in power grids. Some of the EMC interference is mitigated directly at the sources of interference by special filter circuits. However, the remaining interference can propagate and amplify via the supply and control lines. This can have unpredictable effects on controllers, power supplies, sensors, and actuators. Our filters limit the interference directly in front of the potentially susceptible equipment or the sensitive end devices.
Conventional filters only protect against high-frequency interferences, but not against overvoltage pulses. For effective protection, additional surge protection components are needed. SFP2 filters provide effective protection against surges and high-frequency interference as they feature a surge protection circuit that protects both the input and output side of the filter.
Thanks to the simple DIN rail mounting and the variable connection technology, using the filters in the control cabinet is child's play. Choose between the fast Push-in connection technology or proven screw connections for connecting the interference suppression filters.
The connection of the interference suppression filters to the local protective bonding is realized by additional PE terminal points. This improves the filter effect for high-frequency interferences between the active conductors and the ground potential. This way, an EMC-optimized installation and an improved protective effect is also achieved for EMC filters in plastic housings.
