The 1769-OB32T is a compact I/O module. The module has a 32-point output channel that provides a nominal output voltage of 24VDC. It operates in a voltage range of 10.2 and 26.4V DC, with an output delay of 0.5ms for on conversion and 4ms for off conversion. The 1769-OB32T draws 220mA at 5.1V and has a maximum heat dissipation of 4.67W. It has a maximum leakage current (off state) of 0.1mA and a minimum current (on state) of 1.0mA at 26.4V. The 1769-OB32T has A maximum per-point current of 0.5A and a surge current of 2.0A, lasting 10ms and repeating every 2 seconds. The 1769-OB32T has a single slot width and can be mounted on a DIN rail or panel mount. The module weighs approximately 230 grams (0.51 lb) and measures approximately 118 x 35 x 87 mm (4.65 x 1.38 x 3.43 inches) it comes with IEC Class 2 reinforced insulation. The 1769-OB32T has a rated power distance of 8 modules and 0.68 Nm terminal torque screw. It also comes in copper wire in 22 x 14 AWG solid wire size or 22 x 16 AWG stranded wire size.
The Allen-Bradley 1769-OB32T is a 1769 compact I/O module. The module is a discrete output module with thirty-two (32) source output channels with a nominal output voltage of 24 V DC and an output voltage range of 10.3-26.4 V DC. The module is designed to be compatible with the 1769 CompactLogix controller or the MicroLogix 1500 controller. It is a single slot module that can be installed directly into the backplane of the 1769 assembly or the MicroLogix 1500 expansion slot.
The 1769-OB32T output channel has a common current of 2.0 amps, a maximum continuous output current of 4.0 amps per module, and a maximum inrush current of 2. 0 amps, every 2 seconds, for a maximum duration of 10 milliseconds. Each channel exhibited a signal delay of 0.5 ms before opening and 0.4 ms before closing, while the maximum off state leakage current was 0.1 mA @ 26.4 volts DC. In addition, the module has a minimum on-current of 1.0 MA and a maximum on-state voltage drop of 0.3V Dc-@ 0.5 Amperes.
