1 Process Junction Boxes for fieldbus installations Relcom PROCSS JBs asy to install & maintain Standard proven designs reduce project costs Superb corrosion resistance Wide choice of cable gland types All glanding holes are located in the base of the enclosure Generous space for cable terminations Strong, high impact resistance, durable MTL Process JBs are designed for mounting Megablock fieldbus wiring components, terminators, 0 spur connections and P- surge protection devices, in order to meet the exacting requirements of process industry customers. Relcom wiring components have been chosen to connect over 0,000 fieldbus devices on hundreds of projects. With that experience, MTL/ Relcom have learned a lot about fieldbus junction box requirements for harsh environments. Process JBs make it easy to install and maintain the fieldbus system. or example, a minimum of mm (") of clearance is provided for fieldbus cable connections. This ensures that the correct bend radius is maintained when connecting to the full range of MTL/Relcom wiring components. They are available in a choice of materials and finishes that provide strength, durability and corrosion resistance to many chemicals and their vapours. The CS-000 enclosures are manufactured from stainless steel to provide the highest level of corrosion protection. The CS-000 adopt a lower cost solution, by being constructed from 0 stainless steel but with a painted finish that denies most corrosion attacks. The CS-000 enclosures are manufactured from carbonloaded, polyester which combines strength with the highest level of corrosion resistance. A wide choice of glands is available, ready fitted to the junction box: stainless steel, nickel-plated brass and plastic, enabling a high quality seal with standard or wire-armoured cables. All glanding is in the base of the enclosure with a minimum of mm of clearance between the base of the enclosure and other components. This makes glanding much easier, especially when terminating armoured cable. Significant cost savings can be made on a fieldbus project by selecting standard, and proven, fieldbus junction box designs. It eliminates the need for custom designs when choosing junction boxes for fieldbus applications and saves the cost of managing the specification and the eventual procurement of the junction boxes. To select the Process JB appropriate to your application; first decide on the enclosure material, based upon site conditions, required strength, durability and economics; this will define which series you require. Next, determine the number of fieldbus device connections, and hence the number of spur connections required in the junction box. This will also define which Megablocks (and maybe terminators) are required. Use the application examples to help you. Identify any additional items that will need to be housed in the enclosure, e.g. surge protection devices, additional terminators. Calculate how much they will require. Add this to length of the Megablock(s) and choose an enclosure with sufficient rail length. inally, decide on gland type. Is the cable armoured? Does the environment require steel or brass glands, or will plastic be sufficient? See application example tables and ordering information for details on how to fully specify the enclosure in your order.

2 CS-000 Series junction boxes The CS-000 Series enclosures are manufactured from 0 stainless steel with a RAL0 painted finish, to provide high levels of corrosion resistance for process environments. The CS-xx Process JBs are suitable for Zone and Zone intrinsically safe (x i) and increased safety applications (x e). The junction boxes are available pre-drilled for one segment: having trunk-in, trunk-out and spur connections; or a trunk-in and 0 or spur connections; or two segments having a trunk-in and 0 or spur connections. Two-pair multicore trunk cable may be used when only a single trunk gland is available. The wide choice of glands, including stainless steel, nickel-plated brass and plastic, enables a high quality seal with standard or wire armoured cables. The box incorporates a rain channel that prevents standing water from damaging the one-piece seal; diverting it away from the contents when the door is opened. A 0mm earth stud and a breather are also included as standard. An adhesive backed, Traffolyte tag label is supplied loose or can be engraved with the tag number and fitted, if details are supplied when ordering.

4 CS-000 Series junction boxes The CS-000 Series carbon loaded polyester enclosures provide the highest levels of corrosion resistance for the harshest process environments. The CS-xx Process JBs are suitable for Zone and Zone intrinsically safe (x i) and increased safety applications. The controlled surface resistance eliminates the risk of static buildup. The junction boxes are available pre-drilled for one segment: having trunk-in, trunk-out and spur connections; or a trunk-in and 0 or spur connections; or two segments having a trunk-in and 0 or spur connections. Two-pair multicore trunk cable may be used when only a single trunk gland is available. A wide choice of glands, including stainless steel, nickel-plated brass and plastic, enables a high quality seal to be achieved with either standard or wire-armoured cables.
