Diode and Lamp Terminal Blocks
Using the diode terminal blocks of the PT push-in connection terminal blocks makes it possible to solve a variety of switching tasks. The diode is integrated either from left to right or vice versa in the terminal housings. Three and four-conductor terminal blocks are also available for multi-conductor connections.
Integrated diodes (1N 4007) and lamps on certain parts
Push-In technology with 50 % less insertion force for direct plugging from 0.34 mm²
Configurations include lamp test circuits and fault message circuits

Phoenix Contact Feed-Through Terminal Block, Double Level, 250V Maximum Voltage - PTTB 2.5-2DIO/O-UL/UR-UL - 3211430
This double-level feed-through terminal block from Phoenix Contact is an easy way to safely connect wires in a circuit. It features a robust polyamide insulator to protect your equipment from short circuits and current surges. An additional level of security against electrical incidents comes with the integration of blocking diodes to prevent reverse currents or resistance. This makes the unit suited to demanding industrial use, especially in current and voltage limitation and distribution applications.
The block benefits from push-in connection technology for easy, tool-free wiring and a secure contact between conductors. It can handle wire gauges from 26 to 12AWG, giving you a high degree of flexibility over input and output wiring. Because it uses Phoenix Contact’s innovative CLIPLINE complete system, it can be connected easily to other terminals, allowing you to customise the system to your needs.

Push-In Connection Terminal Blocks
The PT series is characterised by easy, direct conductor connection, and it consistently uses the advantages of the CLIPLINE complete system. The up to 50% lower insertion forces of the PT push-in connection method also allows easy and direct plugging of solid and stranded conductors with ferrules of 0.34mm2 and up.
