HONEYWELL SDOL-0424 通道处于打开状态且配置为非冗余
安全回路监控数字输出模块SDOL-0424有四个24 Vdc，1 A
环路监控输出通道，可驱动高达24 W的负载。最大模块
负载为3.6 A。这些负载可以是电阻负载或电感负载。对于感应负载
抑制二极管包括在每个输出上。
输出，包括抑制二极管、导线断裂检测和
短路检测，经过充分测试，因此可以用于安全
应用。
对输出进行以下测试：
•断电能力
•能够通过二次方式断电
•输出之间的串扰
•抑制二极管的功能
•（外部）输出接线中的导线断裂
•输出短路
SDOL-0424模块每个通道有一个LED；总共四个。
如果某个通道处于关闭状态，则其相应的LED熄灭，并发出短暂的间歇性信号
闪烁。这表明正在进行导线断裂试验。
如果通道处于打开状态且配置为非冗余，则其对应的
LED亮起并发出（非常）短暂的周期性闪光，而这些闪光几乎看不见
肉眼可见。这些指示正在进行内部关闭自检。
如果通道处于打开状态并且配置是冗余的，则其相应的指示灯
似乎间歇性闪烁。发生这种情况是因为控制中的模块
处理器2短暂关闭，使控制处理器1中的模块能够
进行自检。控制处理器1中的模块自检完成后
完成后，控制处理器2中的模块再次打开（这可能
花费一些时间），并且控制处理器1中的模块关闭以允许
控制处理器2中的模块执行自检等。因此，它看起来像
如果两个模块的通道LED间歇性闪烁。LED闪烁速度
可能会有所不同，具体取决于应用程序周期时间和
诊断测试间隔。
SDOL-0424模块的环路监控输出通道通常需要
范围设置模块，用于将电流感测电平置于适当范围或
防止在备用通道上检测到引线断裂。为此，范围设置
可以使用模块BSDOL-04UNI。
冗余SDOL-0424模块只需要一个BSDOL-04UNI模块。
BSDOL-04UNI模块放置在
19英寸机箱中IO背板的背面。
The safe loop-monitored digital output module SDOL-0424 has four 24 Vdc, 1 A
loop-monitored output channels to drive loads up to 24 W. The maximum module
load is 3.6 A. These loads may be resistive or inductive. For inductive loads, a
suppression diode is included on each output.
The outputs, including the suppression diode, the lead breakage detection and
short-circuit detection, are fully tested and may therefore be used for safe
applications.
The outputs are tested for:
• Ability to de-energize
• Ability to de-energize via secondary means
• Cross talk between outputs
• Function of the suppression diodes
• Lead breakage in the (external) output wiring
• Short circuit of the outputs
The SDOL-0424 module has one LED for each channel; four in total.
If a channel is Off, its corresponding LED is off and gives short intermittent
flashes. These indicate the lead breakage tests are being performed.
If a channel is On and the configuration is non-redundant, its corresponding
LED is on and gives (very) short periodic flashes, which are hardly visible to the
naked eye. These indicate the internal switch-off self-tests are being performed.
If a channel is On and the configuration is redundant, its corresponding LEDs
appear to flash intermittently. This happens because the module in Control
Processor 2 switches off briefly to allow the module in Control Processor 1 to
perform its self-test. After the self-test of the module in Control Processor 1 has
been completed, the module in Control Processor 2 switches on again (this may
take some time) and the module in Control Processor 1 switches off to allow the
module in Control Processor 2 to perform its self-test, etc. Due to this, it looks as
if the channel LEDs of both modules flash intermittently. The LED flash speed
may vary, depending on the application cycle time and configuration of
Diagnostic Test Interval.
The loop-monitored output channels of the SDOL-0424 module usually need a
range setting module to put the current sense level in the proper range or to
prevent lead breakage detection on spare channels. For this, the range setting
module BSDOL-04UNI can be used.
Redundant SDOL-0424 modules require only one BSDOL-04UNI module.
The BSDOL-04UNI module is placed on a programming connector (Px) on the
back of the IO backplane in the 19-inch chassis.
