Frequently asked questions

The 1771-OFE1 model offers three voltage ranges: +1 to +5V DC, -10 to +10V DC, and 0 to +10V DC. The 1771-OFE2 and 1771-OFE3 models offer current outputs and have different ranges, as described in the manual.

You can configure the last state of the output channels using configuration jumpers on the module. By placing jumpers in the MIN, MID, or MAX positions, you can determine the output value when communication with the processor is lost. The default setting is HOLD LAST VALUE, which means the output will hold the last sent value.

Proper grounding is crucial for the module's operation and safety. The manual provides diagrams and instructions on grounding the I/O chassis and the analog output module itself. Refer to the document for detailed steps and recommendations.

The module has a specified operating temperature range of 32 to 140° F (0 to 60° C) and a storage temperature range of -40 to 185° F (-40 to 85° C). It can operate in relative humidity levels of 5 to 95%, noncondensing. The manual also provides information on shock, vibration, and electromagnetic compatibility requirements.
