Analog Output Module Wiring General Each output should be connected using a good quality shielded wire with the cable shield grounded at the module end. See GFK-0898, Series 90-30 PLC I/O Module Specifications, for more information. Using a Generic Terminal Block or Strip ? Mount a terminal strip inside the control enclosure and run a shielded cable from the terminal strip to each output circuit on the module’s terminal board terminals. ? Ground each cable’s shield at the module end only. Do not connect the shields at the terminal strip end (cut shields off at terminal strip end of cables and insulate with shrink tubing). ? Wire the field device to the terminal strip with shielded cables, grounding the shields at the terminal strip end only (cut shields off at field device end of cables and insulate with shrink tubing). Also, keep the length of exposed (outside of shield) leads at the terminal strip and device ends as short as possible. Direct Method ? Run a shielded cable from each field device (transducer, potentiometer, etc.) directly to the module. ? Connect the conductors to the applicable screws on the module’s terminal board. ? Ground the shield at the module end only, exposing a minimum amount of conductor to the noisy environment. Do not connect the shield at the device end (cut shield off at device end of cable and insulate with shrink tubing).BENTLY 3500/20 125768-01
