SAFEGUARDS AND PRECAUTIONS Read and follow all instructions in this manual carefully, and retain this manual for future reference. Do not use this instrument in any manner inconsistent with these operating instructions or under any conditions that exceed the environmental specifications stated.
(measuring RPM for example) or any source of digital signal not exceeding 12 volts. The F2A1X requires 12-24 V dc input power and consumes less than 100 mA. It can be operated freestanding or can be mounted to a panel using the fixed wings on either end of the device.
– terminal. 2.2 Analog Output The F2A1X Frequency to Analog Converter Module may be equipped with either a Voltage Output (0-5 V dc) or a Current Output (4-20 mA) depending on how the unit was ordered. Connections are made to the half of the 4-way terminal block marked Analog Out.
2.2.1 Voltage Output Option The voltage output is 0 to 5 V dc. Connections for voltage out are made to the terminals marked ANALOG OUT. Connect the positive side of the load to the terminal marked + and the negative or common side of the load to the terminal marked –.
