1771-OFE3 is manufactured by Allen Bradley. It is an analog output module with a current output of 0 to 50 milli-Amps. The outputs are differential and are isolated. There are four outputs in the module. These outputs can be selected by sending 12-bit binary data or a 4 bit BCD value. The module can be powered by the backplane power or an external power supply. The 1771-OFE3 requires a power supply 5 Volts DC at 2.5 Amps. The 1771-OFE3 can be placed in any slot of the 1771 I/O system. It is necessary to note that the module is not placed in the same module group as a discrete high density module and along with AC modules or high voltage DC modules. The configuration jumpers on the 1771-OFE3 are factory set and no adjustments are required for setting the output of the module.
The 1771-OFE3 is designed to comply with the EMC directives, and it is CE certified and UL listed. The 1771-OFE3 is intended to be used in industrial environments. The ambient operating temperature of the environment where 1771-OFE3 is installed should be between 0 to 60 degrees Celsius and the storage temperature should be -45 to 85 degrees Celsius. The 1771-OFE3 has an output capacitance of 0.22 microfarad. The output impedance of the module is more than 1.5 mega Ohms. The 1771-OFE3 has a power dissipation of 13.1 Watts and the thermal dissipation is around 44.5 BTU/hour. There are fault indicators on the device which indicate the status of the module during operation. In case of fault conditions, the red LED is switched ON and the green LED remains OFF.
