The 1769-OB32 belongs to the 1769 Compact I/O. The solid-state device is a discrete output source module manufactured by Allen-Bradley for use in CompactLogix controllers and MicroLogix 1500 controllers.
The 1769-OB32 is a high-density module equipped with thirty-two (32) output channels isolated in two (2) groups of sixteen (16) channels. The module is suitable for applications where there is a lot of I/O and panel space is limited. The module occupies 1.5 slots in the CompactLogix or MicroLogix 1500 chassis to allow maximum support for a controller specific module.
The output channel of this module works in the source input configuration. The individual on-output delay for each channel is measured at 0.1 ms and the OFF output delay is 1.0 ms. Each channel can carry currents of 0.5 A @ 60 °C (140 °F) and 1.0 A @ 30 °C (86 °F).
1769-OB32 occupies a 32-bit register. With access to module registers, monitoring or I/O coercion can be enabled to support debugging of components.
When wring out this module, use 22-14 AWG wire sizes for solid wires and 22-16 AWG wire sizes for stranded wires. Install this module next to any adjacent Compact I/O modules. Ensure the connection to the backplane by ensuring that the mounting latch is properly aligned.
The Allen-Bradley 1769-OB32 is a compact I/O module that is a solid state 24VDC output module. The output module has thirty-two (32) channels, two (2) groups, each group of sixteen (16) channels. The module is wired in the source configuration to provide. The 1769-OB32 operates in a voltage range of 20.4 to 26.4 volts DC with an output delay time of 0.5 ms (on mode) or 4 ms (off mode). It has a current consumption of 5.1 mA at 3000 volts and a maximum heat dissipation of 4.5 watts. The 1769-OB32 module has a maximum turn-off leakage current of 1.0 mA and a minimum conduction current of 1.0 mA at 26.4V.
The Allen-Bradley 1769-OB32 output module has a maximum on-state voltage drop of 1.0 VDC at 1 amp, a maximum current of 0.5 amps per point at 60 degrees Celsius (140 degrees Fahrenheit), and 1.0 amps at 30 degrees Celsius (86 degrees Fahrenheit). The 1769-OB32 has a 2.0 amp surge current that lasts for 10 milliseconds and repeats every 2 seconds. It is a single slot width module, usually mounted on a mounting plate or DIN rail. The module weighs about 450 grams (0.992 pounds) and measures 118 x 52.5 x 87 mm (4.65 x 2.07 x 3.43 inches). It features unique IEC Level 2 enhanced insulation and a power supply distance of 6 modules. The 1769-OB32 module is available in 0.68N-m terminal torque screw, 22 x 14 AWG solid wire size copper wire, or 22 x 16 AWG stranded wire size.
