Do you need surge protection for measurement and control technology that uses very little space and can be securely installed? Our LINETRAB and TERMITRAB product ranges offer solutions for applications that require high channel density.
The surge protective devices in the LINETRAB product range have been reduced to just the most essential functions. This offers significant advantages.
Narrowest surge protective devices for measurement and control
The arresters for the DIN rail are extremely slim, yet can protect up to four signal paths. These surge protective devices therefore set a new standard in the 6.2 mm class: as the narrowest surge protective devices for measurement and control technology.
Protection for more than four signal wires
For compact interface protection for more than four signal wires, a bus system (T-BUS) is available for LIT 2-... and LIT 4-... versions.
You can therefore connect a large number of protective modules together to create a single circuit unit – for 6-wire measurement, for example.
If the bus system is used, fine protection is simultaneously provided between all the signal wires.
A large number of channels in a small amount of space: for many applications this means signal transmission over a design width of just 6.2 mm.
The screw connection in the LINETRAB product range from Phoenix Contact has achieved worldwide success. It provides low contact resistance and high power at the conductor – thanks to the flat contacting.
Connect up to eight LINETRAB modules to the system cable, quickly, easily, accurately, and error-free: with our isolating amplifiers and popular controllers.
This represents a plug and protect solution – from the surge protection level through to the higher-level control system.
The slim modular terminal blocks in the TERMITRAB product range have a design width of 6.2 mm.
Choose between multi-stage protective circuits, some with disconnect knives, for Ex and non-Ex applications.
In addition to its proven screw connection, TERMITRAB also offers versions with spring-cage connection.
When the protective terminal block is snapped on, an electrical connection that is resistant to surge currents is automatically established with the DIN rail.
Finally, to implement the ground connection for an entire row of TERMITRAB terminal blocks, simply ground the DIN rail.
Want to perform measurements in the signal circuit? Not a problem for TERMITRAB modular terminal blocks with disconnect knives.
Simply lift the disconnect knives and the connected signal circuit is disconnected. Now you can carry out the necessary work quickly and safely.
The two-stage protective circuits consist of fast-responding and low-limiting suppressor diodes. While gas-filled surge protective devices ensure a high discharge capacity.
In addition, the protection stages are decoupled by ohmic resistors. This ensures optimum power distribution in the protective circuit.
