AO845 DTM支持将HART DTM连接到其通道

AO845/AO845A 模拟输出模块适用于单个或冗余应用，具有 8 个单极性模拟输出通道。该模块循环执行自我诊断。模块诊断包括：

如果向输出电路供电的工艺电源过低，或者输出电流小于输出设定值和输出设定值>1 mA（开路），则报告外部通道错误（仅在有源通道上报告）。

如果输出电路不能给出正确的电流值，则报告内部通道错误。在冗余对中，模块总线主站将命令模块进入错误状态。

如果出现输出晶体管错误、短路、校验和错误、内部电源错误、状态链路错误、看门狗或错误的 OSP 行为，则会报告模块错误。

The AO845/AO845A analog output module is suitable for single or redundant applications with eight unipolar analog output channels. The module performs a self-diagnosis cycle. Module diagnostics include:

If the process power supply feeding the output circuit is too low, or if the output current is less than the output set value and the output set value is >1 mA (open), an external channel error is reported (only on the active channel).

If the output circuit does not give the correct current value, an internal channel error is reported. In a redundant pair, the module bus master will command the module to enter an error state.

A module error is reported if an output transistor error, short circuit, checksum error, internal power error, status link error, watchdog, or faulty OSP behavior occurs.

8 channels, current of 4... 20 mA

Suitable for single or redundant applications

1 group of 8 channels isolated from the ground

Analog input short-circuit protection to ZP or +24 V
