|Screwless terminal blocks save
time and money. They offer a quick and easy clamping system that is
vibration proof and maintenance free. Just push the spring clamp,
insert the wire and release.
Double-level terminal blocks offer twice the wiring density of feed-through blocks. The DN-QD12X-A version is supplied with an internal jumper to common all four of its connection points.
LED version: This style is available with LED indicator installed. The LED illuminates when voltage is present. The DN-QD12L2-A version is for 12 - 24V AC/DC circuits, and includes current limiting elements.
Diode version: Typically, an inductive load produces a spike (neg.-going) when it is turned off. These terminal blocks with built-in clamping diode help protect your PLC’s output circuits.
