The fire-resistant housing provides physical channel-to-channel isolation, preventing signal cross-talk and short circuits when terminating 4-20 mA HART transmitters or low-voltage DC logic circuits. Screw-clamp terminals accommodate wire sizes ranging from 16 to 22 AWG, maintaining low contact resistance across high-vibration control panel installations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What wire gauge specifications are supported by the compression terminals on the TBCH?\u003c\/p\u003e\n\u003cp\u003eA: The TBCH terminal block supports single-conductor field wiring ranging from 16 to 22 AWG (0.64 mm to 1.30 mm diameter).\u003c\/p\u003e\n\u003cp\u003eQ: How does the TBCH contribute to channel isolation on field I\/O connections?\u003c\/p\u003e\n\u003cp\u003eA: High-dielectric, fire-resistant plastic barriers between adjacent terminals prevent physical contact and maintain channel-to-channel isolation under maximum working voltages.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eVerify that all field power feeds and system backplane power are fully isolated before wiring the TBCH block.\u003c\/li\u003e\n\u003cli\u003eStrip field conductor insulation back 6 to 8 mm, taking care not to nick or nick the copper strand core.\u003c\/li\u003e\n\u003cli\u003eInsert each conductor (16-22 AWG) fully into the designated terminal position and torque the terminal screw to 0.5 Nm.\u003c\/li\u003e\n\u003cli\u003eRoute individual cables through cabinet wire ducts to prevent physical tension on the 36-pin header assembly.\u003c\/li\u003e\n\u003cli\u003eSecure field cable shields to the cabinet ground bar at a single grounding point before plugging the TBCH assembly into the active module base.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48761102368958,"sku":"TBCH","price":172.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/TBCH_20_63c8dca8-b3c9-4516-8796-06ace72416e2.png?v=1787192384","url":"https:\/\/www.autooiltech.com\/products\/honeywell-tbch-36-pin-terminal-block","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
