Multiple Level Terminal Blocks
The terminals with Ex & IECEx approval can be used in a potentially explosive atmosphere. These Terminal Blocks are ideal for use in applications requiring high-density wiring. In the ODL series Terminal Blocks, the top level is offset from the bottom level by half the thickness of the Terminal Block. In ODL2.5A, ODL4UA the terminals can be interlocked. In the ODL2.5(I.S) & CDL4UN(I.S) Terminal Blocks, both levels are internally shorted. The ODLG2.5 & CDLG4 Terminal Block has a feed-through function at the top level and grounding function on the bottom level. These grounding points are appropriately identified by the green-yellow imprint. ODLG2.5(I.S) and CDLG4(I.S) are grounding Terminal Blocks with the same profile of ODL2.5 and CDL4UN Terminal Blocks respectively. Triple level Terminal Blocks are an ideal choice for control systems where sensor and actuator applications are involved. The simplified 3-level connections tremendously increase wiring density in the circuit. The top level of the CTL2.5UH Terminal Block provides connection points for signal wires while the middle and bottom level are used for positive and negative potentials. In applications where switching indication is required a choice of CTL2.5UL & CTL2.5UHL with built-in electronic components is available. Marking tags in a blue and red colour besides the conventional white colour are suggested for effective identification. CTL2.5U(I.S) is internally shorted and CTL2.5UH(I.S)D2 is internally shorted with built-in Diode for reverse polarity protection. CTLG2.5 is a triple-level Terminal Block with an additional connection point for earthing cables.
