8280-414 模拟负载共享数字速度控制的低压版本
【产品详情】
8280-141 型是伍德沃德 723PLUS 模拟负载共享数字速度控制的低压版本。这种数字速度控制用于控制发电机组运行中的往复式发动机的负载和速度。
这包括那些带有弹性耦合器的连接器,因为 8280-414 上的速度信号输入支持使用接近开关(速度信号频率低于 1000 Hz)或磁性拾取器(最小 400 Hz 磁性拾取频率)。其他控制选项包括串联执行器输出、0-1 或 4-20 mA 模拟输出或 4-20 或 0-200 mA 执行器输出。
723PLUS 部件 8280-414 已通过 CSA 认证(I 类,2 区,A、B、C 和 D 组)。根据伍德沃德州长的说法,当该控制器按照产品手册中概述的说明投入使用时,控制器符合 EN50081-2 和 EN50082-2 的要求。
低压型号 8280-414 的标称功耗为 40 W,需要 18 至 40 Vdc 电压源。高压型号(8280-415、8280-481)需要 90 至 150 Vdc 的电压源。 8280-480 和 8280-481 型是额定转速为 130 rpm 或更低的发动机的低速版本。除了这些电压和发动机额定转速差异外,这三种其他型号与 8280-414 相同。

【英文介绍】
The Model 8280-141 is a low-voltage version of the Woodward 723PLUS analog load sharing digital speed control. This digital speed control is used to control the load and speed of the reciprocating engine in the operation of the generator set.
This includes those connectors with elastic couplers, as the speed signal input on the 8280-414 supports the use of proximity switches (speed signal frequencies below 1000 Hz) or magnetic pickers (minimum 400 Hz magnetic pick frequency). Other control options include series actuator outputs, 0-1 or 4-20 mA analog outputs, or 4-20 or 0-200 mA actuator outputs.
723PLUS Part 8280-414 is CSA certified (Class I, Zone 2, Groups A, B, C and D). According to Governor Woodward, when the controller is put into service according to the instructions outlined in the product manual, the controller meets the requirements of EN50081-2 and EN50082-2.
The low-voltage model 8280-414 has a nominal power consumption of 40 W and requires a voltage source of 18 to 40 Vdc. High-voltage models (8280-415, 8280-481) require a voltage source of 90 to 150 Vdc. Models 8280-480 and 8280-481 are low-speed versions of engines rated at 130 rpm or less. Apart from these voltage and engine speed rating differences, these three other models are identical to the 8280-414.
