HONEYWELL 51199930-100晶体管模块
数字输出-总线连接24VDC–CC-PDOB01功能数字输出总线24VDC（DO24V）模块提供可靠的24V数字输出信号，以控制其他工艺设备以及电磁阀和插入式继电器。DO24V可以支持高能量输出，以减少输出回路中的外部元件数量。显著功能•广泛的内部诊断以确保数据完整性•可选冗余•直接/反向输出支持•安全状态（FAILOPT）行为•“无熔丝”短路保护•闭锁，脉冲或脉宽调制输出（每个通道）•电流隔离总线24VDC DO。数字输出总线24VDC可用于内部和外部励磁电源。作为总线输出设备，所有输出共用一个公共回路（接地）。所有输出均由同一电源供电，可以是系统电源，也可以是外部连接的24V电源。当选择来自外部电源时，输出可以与C系列电源系统进行电流隔离。无保险丝短路保护这一独特功能允许在不熔断任何保险丝的情况下存在短路。当特定通道短路时，内部电路会检测到这一点，并切断现场连接的电源。在短路修复之前，通道保持断电状态。FAILOPT C系列DO模块将支持每个通道的FAILOPP参数。输出可以通过配置指示为保持最后一个值，或SHED为安全值。用户可以配置安全值。

Digital Output - Bussed 24VDC – CC-PDOB01
Function The Digital Output bussed 24VDC (DO24V) module provides reliable 24V digital output signals to control other process equipment as well as solenoid valves and interposing relays. The DO24V can support high energy outputs to reduce the number of external components in the output loop. Notable Features • Extensive internal diagnostics to ensure data integrity • Optional redundancy • Direct/Reverse output support • Safe-state (FAILOPT) behaviors • “Fuse-less” short circuit protection • Latched, pulsed or pulse-width modulated output (per channel) • Galvanic isolation Bussed 24VDC DO The Digital Output Bussed 24VDC has provisions for both internal and external field power excitation. As a bussed output device, all of the outputs share a common return (ground). All outputs get their power from the same source, which can be either the system power supply or an externally connected 24V power supply. When selection is from an external source, outputs can be galvanically isolated from the Series C power system. Fuse-less Short Circuit Protection This unique feature allows a short circuit to exist without blowing any fuses. When a particular channel is shorted, internal circuits detect this and remove power to the field connection. The channel remains de-energized until the short circuit is repaired. FAILOPT Series C DO module will support FAILOPT parameter on a per channel basis. The output can be directed by configuration to either HOLD THE LAST VALUE, or SHED to a SAFE VALUE. The safe value can be configured by the user.
Bussed 24VDC DO
The Digital Output Bussed 24VDC has provisions for both internal and external field power excitation. As a bussed output device, all of the outputs share a common return (ground). All outputs get their power from the same source, which can be either the system power supply or an externally connected 24V power supply. When selection is from an external source, outputs can be galvanically isolated from the Series C power system. A wiring option on the IOTA determines if outputs are referenced to the Series C system power or an external field power source. FAILOPT Series C DO module will support FAILOPT parameter on a per channel basis. The output can be directed by configuration to either HOLD THE LAST VALUE, or SHED to a SAFE VALUE. The safe value can be configured by the user. The Digital Output Relay provides a dry contact for isolated low voltage / low current or high voltage / high current discrete output applications. Each relay supports a Form-A or Form-B output based on jumper configuration. The Relay IOTA uses the Digital Output 24V (DO24V) IOM with a special IOTA to support the Relay IOTA. All characteristics of the DO24V IOM are incorporated here.• Each channel user configurable as: • Analog Input • Analog Output • Digital Input • DISOE - Sequence of Events (1ms resolution SOE, 20ms PV scan) • Digital Output • Pulse Input (any four channels) • Open Wire Detection • Electronic short circuit protection1 • Fast Scan (Priority I/O Module Scan) • Safe-state (FAILOPT) behaviors configurable on a per channel basis for Digital / Analog Output • HART 7 support (Analog I/O) • HART Modem per Channel for Fast Performance • Extended Temperature Range -40 to +70°C module ambient
