8C-PCNT02 HONEYWELL 数字输出总线24VDC

函数
数字输出总线24VDC (DO24V)模块可以切换可靠的24V数字输出信号来控制其他工艺设备以及电磁阀和插入继电器。
显著的特征
•广泛的内部诊断，以确保数据完整性
•可选冗余
•安全状态(FAILOPT)行为
•锁存，脉冲或脉宽调制输出(每通道)
•电流隔离(系统到现场仅使用外部用户供电)
总线24VDC DO
数字输出总线24VDC有内部和外部励磁磁场的规定。作为一个总线输出设备，所有的输出共享一个共同的返回(地)。所有输出的电源都来自同一个电源，这个电源可以是系统电源，也可以是外接的24V电源。当选择来自外部电源时，输出可以与系列8电源系统进行电隔离。IOTA上的接线选项确定输出是否参考系列8系统电源或外部现场电源。
安全状态行为(FAILOPT)
系列8 DO模块将支持每个通道的FAILOPT参数。可以通过配置将输出定向到HOLD The LAST VALUE或SHED到一个SAFE VALUE。安全值可由用户自行配置。

8C-PDILA1

Function
The Digital Output bussed 24VDC (DO24V) module can switch reliable 24V digital output signals to control other process equipment as well as solenoid valves and interposing relays.
Notable Features
• Extensive internal diagnostics to ensure data integrity
• Optional redundancy
• Safe-state (FAILOPT) behaviors
• Latched, pulsed or pulse-width modulated output (per channel)
• Galvanic Isolation (System to Field only with external user supplied power)
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 8 power system. A wiring option on the IOTA determines if outputs are referenced to the Series 8 system power or an external field power source.
Safe-state Behavior (FAILOPT)
Series 8 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.
