Material Composition FR4 flame retardant PCB base Nylon flame retardant terminal block Tinned copper terminal pins Steel DIN rail elastic clip Polycarbonate channel marking cover Nickel plated copper power bus bar ABS plastic module locking buckle
Structural Features Flat rectangular backplane structure. One side is row of slots for plugging MTL AIO barrier modules. Two rows of screw terminals are arranged on front side, field terminal and control side terminal separated. Built-in power distribution bus runs through all slots. DIN rail clip is installed on back side. Each channel has printed channel number marking. Locking buckle on each slot fixes barrier module.
Working Principle Field intrinsically safe analog signal enters field side terminal of backplane. The signal passes through MTL barrier module inserted on the slot. The barrier limits energy and transfers safe analog signal to control side terminal. Control side terminal connects to Honeywell DCS I/O module. The backplane distributes 24VDC power supply to each barrier module through internal power bus.
Installation Requirements Mount the backplane on 35mm DIN rail or flat cabinet surface with screws. Wire field hazardous side cable to field terminal and control cabinet cable to control side terminal. Insert MTL4544 or MTL4549Y analog barrier into each slot and lock buckle. Connect 24VDC power supply to backplane power terminal. Verify power and signal continuity after wiring. Separate hazardous zone wiring and safe zone wiring strictly.
Usage Notes Only certified intrinsically safe barrier modules can be used on this backplane. Do not mix digital barrier modules on this AIO backplane. Field wiring must comply with ATEX intrinsic safety installation standard. Do not exceed the rated voltage of terminal. Tighten terminal screws to specified torque to avoid heat and poor contact.
