The 1764-OF4 by Allen-Bradley and Rockwell Automation is a 4-channel Analog Voltage/Current Output Module. This module has 4 single-ended, unipolar, outputs and continuous open and short-circuit protection. With regard to converter type, it has an R-2R Ladder Voltage Switching D/A converter type. General specifications include a storage temperature between -40 and 85 degrees Celsius and an operating temperature between -20 and 65 degrees Celsius. Operating humidity is 5% to 95%, non-condensing. Operating vibration is 10…500 Hertz, 5G, 0.030 inches maximum, peak-to-peak.

The 1764-OF4 has dimensions of 90 x 87 x 40 millimeters, or 3.54 x 3.43 x 1.58 inches, as well as an approximate shipping weight of 235 grams, or 0.517 pounds. It has a maximum bus current draw of 40 milliAmps at 5 Volts DC and 50 milliAmps at 24 Volts DC. The 1764-OF4 module has a unipolar 12 bit resolution and a repeatability of ±0.12%. Analog normal operating voltage range is 0…10.5 Volts DC and analog normal operating current range is 4…20 millIAmps. This hardware has a full scale analog voltage range of 0…10.5 Volts DC and a full scale analog current range of 0…21 milliAmps. Output specifications for the 1764-OF4 include a reactive load current output of ˂ 0.1 mH and a typical overall accuracy of ± 1.17% full scale at -20…65 degrees Celsius.

The 1762-OF4 by Allen Bradley / Rockwell Automation is designed to perform its role as an analog output module. This unit, more specifically, is a MicroLogix 1200 analog output module. This module has four (4) channels for both voltage and current. These four (4) outputs of the output module are all single-ended or unipolar. The output voltage provided by the module ranges from 0 to 10 volts direct current (DC) and the current ranges from 4 to 20 milliamperes (mA). Output signals from the module can run modulating actuators and devices. Therefore, the Bulletin 1762 output module, or the MicroLogix 1200 analog output module, has its main applications in an industrial environment.

This analog output module should be used preferably in a clean and dry environment. The dimensions of this analog output unit are 90 millimeters x 40.4 millimeters x 87 millimeters (height x width x depth). The weight of the output module, along with its packaging, is approximately 235 grams (g). This Allen Bradley module has an operating temperature that should remain within a range of -20 degrees Celsius to +65 degrees Celsius, or the equivalent range of -4 degrees Fahrenheit to +149 degrees Fahrenheit. When storing this device, the recommended temperature should range from -40 degrees Celsius to +85 degrees Celsius, or -40 degrees Fahrenheit to +185 degrees Fahrenheit. The relative humidity of the area surrounding this device should have levels that range from 5% to 95% with no condensation. This unit can withstand an operating shock rated up to 30 G.
