AO84模擬輸出模塊適用于單個(gè)或幾余應(yīng)用，具有8 個(gè)單極性模擬輸出通道該模塊循環(huán)執(zhí)行自我診斷。模塊診斷包括:
1.如果向輸出電路供電的工藝電源過(guò)低，或者輸出電流小于輸出設(shè)定值和輸出設(shè)定值>1mA (開(kāi)路)，則報(bào)告外部通道錯(cuò)誤 (僅在有源通道上報(bào)告)
2.如果輸出電路不能給出正確的電流值，則報(bào)告內(nèi)部通道錯(cuò)誤。在幾余對(duì)中，模塊總線主站將命令模塊進(jìn)入錯(cuò)誤狀態(tài)。
3.如果出現(xiàn)輸出晶體管錯(cuò)誤、短路、校驗(yàn)和錯(cuò)誤、內(nèi)部電源錯(cuò)誤、狀態(tài)鏈路錯(cuò)誤、看門(mén)狗或錯(cuò)誤的 OSP 行為，則會(huì)報(bào)告模塊錯(cuò)誤。

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.
AO84 Product Introduction: 8 channels, the current is 4… 20 mA, suitable for single or several applications, 1 set of 8 channels isolated from the ground
Analog input short-circuit protection to ZP or + 24V, HART through communication
