YOKOGAWA CP345-S1处理器板模块
输出端接组件输入输出或带配电的输出（用户通过终端组件上的终端提供）。在两种配置中，当FBM输出打开时，继电器线圈通电，继电器触点从常闭（NC）位置切换到常开（NO）位置。FBM+24 V dc辅助电源用于为继电器线圈通电。带配电装置的终端组件有一个专用接线板，用于连接外部电源，并在终端组件内部分配至每个输出通道。电源线或正极熔断；电源的中性或负极连接到磁场。16通道，开关（每个通道都有保险丝保护）冗余电源15至60 V dc（外部电源），最大电流为2 A，配电组隔离由终端组件提供最大电流限制为每8通道12 A。基于2 A电流的输出电感负载限制。电流每减少2倍，电感限制增加4倍。对于高于规定限值的电感负载，直流电感负载需要缓冲二极管，交流电感负载需要MOV（金属氧化物变阻器）。二极管额定电流必须等于最大负载电流，额定电压必须等于最大电源电压的1.3倍。MOV的额定值必须为120 V ac，额定电流必须等于最大负载电流。（b） PA是聚酰胺，额定温度为-20至+70°C（-4至+158°F）。（c） c=带有压缩端子的TA。RL=带环形接线片端子的TA。刀具有压缩端子。（d） 电缆零件号见表2。（e） 见表1终端组件认证定义。（f） 有关继电器触点额定值的更多详细信息，请参见第15页。（g） 这是刀断开结构。刀片和测试插座仅用于电路验证。刀式断开装置不适用于中断负载。断开电路前必须切断电源。
终端组件认证
类型认证类型1 TA是UL/UL-C列出的适用于I级的TA；A-D组；2类温度代码T4危险场所。它们是DEMKO认证的EEx nA IIC T4，用于2区潜在爆炸性环境。2类TA是UL/UL-C列出的相关设备，用于提供I级非易燃现场电路；A-D组；当连接到指定的200系列FBM和满足《标准和紧凑型200系列子系统用户指南》（B0400FA）中规定的实体参数约束的现场电路时，第2类危险位置。它们还被DEMKO认证为为IIC组2区潜在爆炸性环境提供现场电路的相关设备。如果客户提供的设备满足2类限制，则现场电路也属于2类限制能量（60 V dc、30 V ac、100 VA或更少）。如果客户提供设备满足2级限制，则所有现场电路都属于2类有限能量（60 V dc、30V ac和100 VA或更低）。类型5 TA及其现场电路仅用于普通（非危险）位置。P/PVC电缆装配聚氨酯外护套和半硬质PVC一次导体绝缘温度范围：-20至+70°C（-4至158°F）。4H P/PVC（a）（b）（b。类型4 LSZH（c）（c）低烟无卤或低烟无卤素（LSZH）是用于电缆护套的材料分类。LSZH由热塑性或热固性化合物组成，当暴露于高热源时，它们会释放出有限的烟雾和无卤素。温度范围：-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).
