About 1764-28BXB

The base unit 1764-24BXB is a 1764 MicroLogix component that is used as installation chassis of the 1764 MicroLogix modules, including the controller modules 1764-LSP and 1764-LRP. The module has an internal electronic circuitry that when supplied with a 20.4 to 30V dc line supply range, provides power to the backplane which in turn activates the attached modules. Modules that are compatible for installing to this base unit are Data Access Tool, Real-Time clock, Memory and MicroLogix Controller. The base unit a 16 inputs capable of sink/source wiring configuration, composed of 8 Standard 24VDC and 8 Fast Input with switching frequency of 20kHz. The output in total are 12 output points composed of 6 relay output, 4 Standard 24VDC FET Transistors and 2 Fast output with a frequency of 20kHz. The base unit is paired with MicroLogix processors 1764-LSP and 1764-LRP. The Height dimensions differ when the latch is open or closed. It has dimensions of Height 138 mm (5.43 in.) - Latch open; 118mm (4.65 in.) - latch closed; Width168 mm (6.62 in) and Depth (87 mm (3.43 in). The base unit can support horizontal installation only through a DIN rail or direct panel mounting. Always allows 50 mm (2inch) clearance on all sides for ventilation. The 1764-24BXB has 3 input groups, groups 0-2 with each group having a common terminal - DC COM 1, DC COM 2 and DC COM 3. The first Input group is through I/0 to I/3, I/4 to I/7 and I/8 to I/11. Additionally, the output also come in groups of 4. Ensure environmental specifications have been met in the installation area. The base unit can operate at a vibration rating of 10 to 500 Hz, 5G, 0.030 in. max. peak-to-peak and for Relay Operation, 2G. The MicroLogix 1764 Family is configured using RSLogix500 software.
