The 1771-CFM module is a configurable type of flow meter module. It is manufactured by Allen-Bradley/Rockwell Automation and is part of the PLC 5 series. The 1771-CFM configurable flowmeter module supports four digital I/ OS with digital outputs operating at 5 to 40 V DC. The meter module uses a magnetic pickup, namely the Bently 3300 close to the pickup. The 1771-CFM configurable flowmeter module can be installed by simply plugging 1 slot in the case and is protected from corrosive chemicals by a conformal coating.
The configurable flowmeter module has four input channels, and it can control up to four outputs based on the values received from the input channels. The user can select four modes of operation on this device: non-resettable accumulator mode, accumulator mode, high resolution frequency mode (channel 0/1 or channel 2/3), and orientation sensor mode (channel 0/1 or channel 2/3). The device has a maximum input frequency of 100 kHz, a maximum count value range of 0 to 9.999.999 (programmable), and a maximum processing time of 5.5 milliseconds. The backplane power supply current is 1 amp. Power consumption ranges from 2 to 13 watts. For diagnostic purposes, the module sends diagnostic information to the PLC processor in words available to the programmer in the configuration module. The module should operate at temperatures between 0 and 60 degrees Celsius (32 and 140 degrees Fahrenheit).
