|Question: We will be installing and data logging 12 flowmeters around our plant. Some with 4-20mA outputs and others with pulsed outputs. Is there a way to totalize the flows remotely over Ethernet so our DCS can simply read back the totalized flows periodically.|
Answer: Yes, our 967EN-4008 and 989EN-4016 Ethernet Remote I/O can totalize and store the accumulated flows in non-volatile memory. The 967EN-4008 has 8 current inputs where each input is sampled every 8 mS then added. The 989EN-4016 has 16 DIO where 8 channels can be used as up or down counters. The remaining 8 channels can be output alarms for the associated counter inputs. Your DCS would communicate with the Remote I/O using Ethernet Modbus TCP/IP.
