By integrating protection for the excitation, signal, and sense lines into a single ultra-compact DIN rail unit, the ZBA1S simplifies installation, reduces wiring complexity, and saves valuable panel space — making it the ideal barrier for Zone 1 gas, Zone 21 dust, and mining (M1) environments.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThree-channel design protects the Excitation (CN3\/CN6), Signal (CN1\/CN4), and Sense lines simultaneously — all in one device.\u003c\/li\u003e\n\u003cli\u003eSupports connection of up to 4 × 350 Ω load cells.\u003c\/li\u003e\n\u003cli\u003e\"SLIM\" hyper-compact DIN rail enclosure — ideal for space-constrained installations.\u003c\/li\u003e\n\u003cli\u003eDual ATEX and IECEx certified for gas (Zone 1), dust (Zone 21), and mining (M1) applications.\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: −20 °C to +60 °C.\u003c\/li\u003e\n\u003cli\u003eAvailable as a standalone barrier (ZBA1S) or pre-installed in an ATEX-certified ABS enclosure with 4 certified cable glands (KZBA).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eATEX \/ IECEx Marking\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eATEX: II (1)G, II (1)D, I (M1)\u003c\/li\u003e\n\u003cli\u003eIECEx: \u0026lt;Ex ia Ga\u0026gt; IIC, \u0026lt;Ex ia Da\u0026gt; IIIC, \u0026lt;Ex ia Ma\u0026gt; I\u003c\/li\u003e\n\u003cli\u003eTemperature range: −20 °C ≤ Tamb ≤ +60 °C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eElectrical Ratings\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN3 (Excitation): 14 Vrms differential, 8 Vrms through earth\u003c\/li\u003e\n\u003cli\u003eCN1 \u0026amp; CN2 (Signal \/ Sense): 20 Vrms\u003c\/li\u003e\n\u003cli\u003eMaximum Security Voltage (Um): 250 Vrms\u003c\/li\u003e\n\u003cli\u003eMaximum Security Current (interruption capability): 1,500 A\u003c\/li\u003e\n\u003cli\u003eDegree of protection: IP20 (barrier only)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKZBA Enclosure Option\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: ABS\u003c\/li\u003e\n\u003cli\u003eCable glands: 4 × ATEX-certified glands included\u003c\/li\u003e\n\u003cli\u003eGas protection: ATEX II 3(1) Ex nAa \u0026lt;ia Ga\u0026gt; IIC T4 Gc (−20 °C ≤ Ta ≤ +50 °C)\u003c\/li\u003e\n\u003cli\u003eDust protection: ATEX II 3(1)D Ex tb \u0026lt;ia Da\u0026gt; IIIC T130 °C Dc IP65 (−20 °C ≤ Ta ≤ +50 °C)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Combined use of one or more Zener barriers classified (1)GD \u0026lt;Ex ia\u0026gt; requires the overall barrier set marking to be upgraded to (2)GD \u0026lt;Ex ib\u0026gt; in accordance with EN 60079-14.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Dini Argeo","offers":[{"title":"ZBA1S","offer_id":44926585602370,"sku":null,"price":320.0,"currency_code":"GBP","in_stock":true},{"title":"KZBA","offer_id":44926585635138,"sku":null,"price":750.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/6800\/8002\/files\/ZBA1S_ex_w.png?v=1784552486","url":"https:\/\/www.womag.co.uk\/products\/atexiecex-triple-zener-barrier-load-cells-zba1s","provider":"Womag","version":"1.0","type":"link"}
