終端組件認證
類型認證類型1 TA是UL/UL-C列出的適用于I級的TA；A-D組；2類溫度代碼T4危險場所。它們是DEMKO認證的EEx nA IIC T4，用于2區(qū)潛在爆炸性環(huán)境。2類TA是UL/UL-C列出的相關(guān)設(shè)備，用于提供I級非易燃現(xiàn)場電路；A-D組；當連接到指定的200系列FBM和滿足《標準和緊湊型200系列子系統(tǒng)用戶指南》（B0400FA）中規(guī)定的實體參數(shù)約束的現(xiàn)場電路時，第2類危險位置。它們還被DEMKO認證為為IIC組2區(qū)潛在爆炸性環(huán)境提供現(xiàn)場電路的相關(guān)設(shè)備。如果客戶提供的設(shè)備滿足2類限制，則現(xiàn)場電路也屬于2類限制能量（60 V dc、30 V ac、100 VA或更少）。如果客戶提供設(shè)備滿足2級限制，則所有現(xiàn)場電路都屬于2類有限能量（60 V dc、30V ac和100 VA或更低）。類型5 TA及其現(xiàn)場電路僅用于普通（非危險）位置。P/PVC電纜裝配聚氨酯外護套和半硬質(zhì)PVC一次導(dǎo)體絕緣溫度范圍：-20至+70°C（-4至158°F）。4H P/PVC（a）（b）（b。類型4 LSZH（c）（c）低煙無鹵或低煙無鹵素（LSZH）是用于電纜護套的材料分類。LSZH由熱塑性或熱固性化合物組成，當暴露于高熱源時，它們會釋放出有限的煙霧和無鹵素。溫度范圍：-40至+105°C（-40至+221°F）。
The output termination assemblies
come in either output or output with power distribution (usersupplied via terminals on the termination assembly). In both configurations, when the FBM output is on, the relay coil is energized and the relay contact is switched from normally closed (NC) position to the normally open (NO) position. The FBM +24 V dc auxiliary power supply is used to energize the relay coil. Termination assemblies with power distribution have a dedicated terminal block which provides a connection to externally supplied power and distributed internally on the termination assembly to each of the output channels. The line or positive side of the supply is fused; the neutral or negative side of the supply is connected to the field.16 channel, switch (each channel is protected - fused) Redundant power 15 to 60 V dc (externally sourced) at 2 A maximum with power distribution Group isolation provided by termination assembly Maximum current is limited to12 A per 8 channels. Output inductive load limits based on current of 2 A. Inductance limit increases by a factor of 4, for each factor of 2 reduction in current. For an inductive load above stated limits, a snubber diode is required for a dc inductive load or a MOV (metal oxide varistor) is required for an ac inductive load. Diode current rating must be equal to the maximum load current and voltage rating equal to 1.3X maximum supply voltage. MOV must be rated for 120 V ac use and current rating must be equal to maximum load current. (b) PA is polyamide rated from -20 to +70°C (-4 to +158°F). (c) C = TA with compression terminals. RL = TA with ring lug terminals. Knife has compression terminals. (d) See Table 2 for cable part numbers. (e) See Table 1 Termination Assembly certification definitions. (f) See Page 15 for more detail on the relay contact rating. (g) This is knife disconnect construction. Knives and test sockets provided for circuit validation only. Knife disconnects are not rated for interrupting loads. Power must be removed before disconnecting circuit.
Certifications for Termination Assemblies
Type Certification Type 1 TAs are UL/UL-C listed as suitable for use in Class I; Groups A-D; Division 2 temperature code T4 hazardous locations. They are DEMKO certified EEx nA IIC T4 for use in Zone 2 potentially explosive atmospheres. Type 2 TAs are UL/UL-C listed as associated apparatus for supplying non-incendive field circuits Class I; Groups A-D; Division 2 hazardous locations when connected to specified 200 Series FBMs and field circuits meeting entity parameter constraints specified in Standard and Compact 200 Series Subsystem User’s Guide (B0400FA). They are also DEMKO certified as associated apparatus for supplying field circuits for Group IIC, Zone 2 potentially explosive atmospheres. Field circuits are also Class 2 limited energy (60 V dc, 30 V ac, 100 VA or less) if customersupplied equipment meets Class 2. Type 4 All field circuits are Class 2 limited energy (60 V dc, 30 V ac, 100 VA or less) if customer-supplied equipment meets Class 2 limits. Type 5 The TA and its field circuitry are for use in only ordinary (non-hazardous) locations.P/PVC cable assembles polyurethane outer jacket and semi-rigid PVC primary conductor insulation temperature range: -20 to + 70°C (-4 to 158°F). Type 4H P/PVC(a)(b) (b) Type 4H cables are used to reduce voltage drop in long (greater than 5 m (15 ft)) cable run applications.
