It functions as a single-slot, non-redundant, passive interface baseplate that connects one S800 I\/O module to the ModuleBus. Engineered with a three-row compression screw terminal block configuration featuring increased cross-sectional wire capacity, the TU837 provides robust field-side signal aggregation and loop power distribution without active electronic components on the board.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: The TU837 is functionally identical to the TU837V1 variant (Part Number: 3BSE013238R1), sharing the exact same mechanical footprint, terminal ratings, and physical channel routing profiles.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Extended Module Termination Unit (MTU) for Non-Redundant Configurations\u003c\/li\u003e\n\u003cli\u003eModel Code: TU837 \/ TU837V1\u003c\/li\u003e\n\u003cli\u003ePart Number Alliance: Associated with 3BSE013238R1\u003c\/li\u003e\n\u003cli\u003eManufacturer: ABB\u003c\/li\u003e\n\u003cli\u003eSystem Family Compatibility: S800 I\/O System (Accepts various 800-series modules)\u003c\/li\u003e\n\u003cli\u003eChannel \/ Module Capacity: Single-slot layout (1 module per MTU)\u003c\/li\u003e\n\u003cli\u003eTerminal Design Framework: Three-row heavy-duty compression screw terminal block architecture\u003c\/li\u003e\n\u003cli\u003eMaximum Rated Isolation Voltage: 50 V\u003c\/li\u003e\n\u003cli\u003eSignal Connection Wire Sizes: Solid: 0.2 to 6.0 mm² \/ Stranded: 0.2 to 4.0 mm² (24 to 10 AWG)\u003c\/li\u003e\n\u003cli\u003eReturn Connection Wire Sizes: Solid: 0.2 to 4.0 mm² \/ Stranded: 0.2 to 2.5 mm² (24 to 12 AWG)\u003c\/li\u003e\n\u003cli\u003eRecommended Terminal Screw Torque: 0.5 to 0.6 Nm\u003c\/li\u003e\n\u003cli\u003eIngress Protection Rating: IP20 (IEC 60529 Compliant)\u003c\/li\u003e\n\u003cli\u003eConformal Coating: Factory standard protection for harsh environment reliability\u003c\/li\u003e\n\u003cli\u003eMounting Style: Horizontal or Vertical 35 mm DIN Rail\u003c\/li\u003e\n\u003cli\u003ePhysical Dimensions: 20.4 cm x 5.6 cm x 4.7 cm\u003c\/li\u003e\n\u003cli\u003eProduct Net Weight: 0.32 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSnap the TU837 MTU firmly onto the cabinet DIN rail until the rear locking mechanism fully engages.\u003c\/li\u003e\n\u003cli\u003eEnsure the integrated grounding clip makes solid, paint-free contact with the metallic rail to guarantee reliable noise rejection.\u003c\/li\u003e\n\u003cli\u003eSet the mechanical keying wheels on the MTU face to exactly match the designated keying profile of the target S800 I\/O module before slotting the electronics in.\u003c\/li\u003e\n\u003cli\u003eTerminate field lines using correct wire strip lengths (8 mm for signal, 7 mm for return connections) and tighten screws to the recommended 0.5–0.6 Nm torque threshold.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53620896235704,"sku":"TU837","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/6132\/3704\/files\/TU838_2_r270.png?v=1782293543","url":"https:\/\/www.globalpetroparts.com\/products\/abb-tu837-extended-module-termination-unit","provider":"Global Petro Parts Automation","version":"1.0","type":"link"}
