The 1762-OV32T is an output module manufactured by Allen-Bradley and designed under the standards of the MicroLogix 1762 Series of drives. This module is a solid-state sink output module. The importance of output modules lies in the fact that these units can convert digital values that are generated by the CPU module of the Programmable Logic Controller (PLC) into analog values. These modules serve as a communication bridge between a drive and the CPU of its respective controller. The 1762-OV32T solid-state sink output module has certain general features, such as 32 outputs, a heat dissipation of 2.7 kW at 26.4 Volts DC, and a maximum bus current draw of 175 mA at 5 Volts DC. As a protective measure, the 1762-OV32T solid-state sink output module should be installed and kept in an IP20 general purpose enclosure, as this will allow the module to withstand a high exposure to dusty environments, specifically environments with pollution degree of 2. It is utterly important that users be aware of this enclosure’s capabilities and limits, including the fact that this enclosure cannot protect the unit from contact with liquids or ice formations.
This module can operate at an altitude of 2000 meters (6562 feet) without derating, at a maximum relative humidity range of 95%. The temperature surrounding this module while it is operating should not drop below or exceed -20 or 60 degrees Celsius (-4 to 140 degrees Fahrenheit). In terms of this module’s installation process, it is important to leave a clearance of 50.8 millimeters (2 inches) on each side of the module, in order to allow a proper ventilation and prevent the module from overheating; in addition, the 1762-OV32T terminal needs must be included in a grounding system, in order to limit the electric noise. The approximate dimensions of this 1762-OV32T output module are 90 x 40.4 x 87 millimeters (3.54 x 1.59 x 3.43 inches) and it has an approximate shipping weight of 200 grams (7.05 ounces).
