AO84 8 个单极性模拟输出通道 冗余控制

AO84模拟输出模块适用于单个或几余应用，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:
1.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>1mA (开路)，则报告外部通道错误 (仅在有源通道上报告)
2.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。在几余对中，模块总线主站将命令模块进入错误状态。
3.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。
AO84产品介绍：8 个通道，电流为 4…20 mA、适用于单个或几余应用程序、1 组8 个通道与地面隔离
、模拟输入短路保护至ZP或+24 V、HART直通通信

The AO84 analog output module is suitable for single or several applications with 8 unipolar analog output channels. Module diagnostics include:
1. If the process power supply to the output circuit is too low, or the output current is less than the output setpoint and the output setpoint >1mA (open circuit), an external channel error is reported (only reported on the active channel).
2. If the output circuit does not give the correct current value, the internal channel error is reported. In a few pairs, the module bus master will command the module to enter an error state.
3. If an output transistor error, short circuit, checksum error, internal power error, status link error, watchdog, or faulty OSP behavior occurs, a module error is reported.
