1769-BOOLEAN

The Allen-Bradley 1769-BOOLEAN comes with an LED display and an open-type enclosure. It measures 3.34 inches in depth, 4.65 inches in height and 1.38 inches in width, and it weighs approximately 0.625 lb. It has a 10-30V DC input signal and a 20.4 - 26.4V DC output signal. It features a closed loop time of 1 microsecond and it can mount on a DIN-rail or panel mount. The 1769-BOOLEAN module is a combination of 24V DC input/output.  Its outputs can be controlled using Boolean expressions or controlled directly from the program. When the expression is TRUE, it signifies output as ON state. And when it is FALSE, the output channel is at OFF state. The module's Boolean expression has 4 operations to configure, OR, AND, XOR, or NONE.

The 1769-BOOLEAN module comes with eight single-ended 24V DC inputs and four single-ended 24V DC sourcing outputs. The sourcing describes how the current flows in I/O and the field device. It has a 220-mA max current draw at 5.1V and a draw of 0 mA at 24V. Its heat dissipation reaches 3.55 W at most. The 1769-BOOLEAN’s isolation voltage is 75V DC and it is rated to withstand 1200V AC for 1 s or 1697V DC for 1 s in dielectric tests. Its isolation voltage is IEC verified class 2 reinforced insulation type.

The 1769-BOOLEAN comes with 8 virtual and real inputs and 24V AC sinking voltage. The module has an operating voltage range 10-30 V DC at 30 °C and 10-26V DC at 60 °C. It has 10 μs OFF-ON and ON-OFF input delay and an input impedance which is 2.0 kΩ at 24V DC and 2.3 kΩ at 30V DC.
