Connectwell triple level terminal blocks are an ideal choice for the control system where sensors and actuator applications are involved. The simplified three level connections tremendously increase wiring density in the circuit. Ctl2.5 with feed through connecting points at all the three levels offer multiple choice of signal and power distribution at any level. In ctl2.5u[h], the top level provides connecting points for signal while middle at bottom level connecting points are used for positive and negative potentials. Use of cross connecting aids is recommended for making common potentials. Marking tags in blue and red colour besides conventional white colour is suggested for effective identification. The terminal blocks are designed for universal rail mounting.In application where switching indication is required, choice of [ctl2.5u[e][ triple level terminal blocks with built-in electronic components is available.
