Description

Brand:                                        Allen Bradley

Model No :                                 1794-OB16

Type:                                         Flex I/O Digital DC Output Module

The Allen-Bradley 1794-OB16 module is a FLEX I/O digital DC output module. It has a total of 16 active sourcing outputs. The lowest, maximum and nominal on-state voltages are 10 volts direct current, 31.2 volts direct current, and 24 volts direct current, respectively. All 16 outputs (each rated at 0.5 Amps) have an output current rating of 8 Amps, while the lowest on-state current is 1 milliamp per channel and the maximum on-state current is 500 milliamps per channel. The maximum on-state voltage drop is 0.5 volts direct current (VDC). The surge current is 2 amps for 50 milliseconds, and it can be repeated every 2 seconds. Off-state leakage current is limited to 0.5 milliamps. The constant isolation voltage is 50 volts.

Output:

The 1794-OB16 module’s output signal delay is 0.5 milliseconds off-to-on and 1-millisecond on-to-off. At 5 Volts DC, the FlexBus current is 80 milliamps, resulting in 5.3 Watts of maximum power consumption at 31.2 Volts DC. The 1794-OB16 module has a heat loss of 18.1 BTU per hour. The highest off-state voltage is 31.2 volts direct current. The module is 3.7 x 3.7 x 2.7 inches. The 1794-OB16 module weighs approximately 78 grams. For field-side status indication, the module features 16 yellow indicators. The size of the wire is determined by the established terminal base. The module has an open enclosure and adheres to the IEC temperature code T3. The temperature range for operation is -4 to 131 degrees Fahrenheit.

Dimensions:

This module includes sixteen (16) 24VDC Discrete output channels for source wiring design. The 1794-OB16 has an output voltage range of 10 to 31.2VDC with a nominal output voltage of 24VDC. It has dimensions of 94 x 94 x 69 mm (3.7 x 3.7 x 2.7 in.) and a weight of 78 g (2.75 oz.). This module has sixteen (16) field-side LED indicators.

The 1794-OB16 has an operating temperature range of 0 to 55 °C (32 to 131 °F) and a storage temperature range of 55 °C (131 °F), respectively, with shock and vibration ratings of 30g and 5 g @ 10 to 500 Hz. This module is certified by c-UL-us, CSA, CE, Ex, TÜV, KC, EAC, and RCM.
