Channels 22, 23, and 24 are configured to draw 10 mA to support special field contacts requiring higher wetting currents to pierce oxidized surface films.\u003c\/p\u003e\n\u003cp\u003eQ: What function do the polymer positive temperature coefficient (PTC) fuses perform on this assembly?\u003c\/p\u003e\n\u003cp\u003eA: The PTC fuses serve as resettable overcurrent protection blocks for the 24 VDC internal excitation distribution system. If an external field-side short occurs, the fuse self-heats into a high-resistance state to clamp the loop current at 0.5 A, resetting automatically once the field fault is cleared and the component cools down.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis Layout Alignment, Clearance Constraints, and Mechanical Seating:\u003c\/strong\u003e Snap the assembly along with its plastic insulator onto a standard industrial DIN rail, or bolt the metal carrier directly into the designated slot inside the cabinet. If deploying an option card like the WROB, seat it firmly onto connectors JW1 and JW2, ensuring a 50 mm convective cooling clearance around the module boundaries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Separation, Wireway Constraints, and Shield Grounding:\u003c\/strong\u003e Route external field loops through distinct wiring tracks using #18 AWG wires, running the relay coils to terminal block TB1 and the contact sensing loops to TB2. Strip individual cable sleeves at entry and ground all drain shields on a separate panel bracket to redirect high-frequency electromagnetic noise away from the internal measurement logic.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":47904042844350,"sku":"IS200TDBSH2A（IS230TNDSH2A)","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-30_10-39-10_c7cef24d-68a2-4a5d-913d-adc7a4c6ff7e.png?v=1782973174","url":"https:\/\/www.autooiltech.com\/products\/ge-is200tdbsh2a-is230tndsh2a-relay-output-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
