1756-OB16 discrete output module

The 1756-OB16 is an Allen Bradley brand discrete output module.

Product Description:

The 1756-OB16 is a 16-channel I/O module for use with ControlLogix and CompactLogix controllers. It operates on 24 to 28 volts DC, has a relay output type, and draws 1 amp per output. The operating temperature range is – 40 to 125 degrees Fahrenheit and the storage temperature range is – 40 to 150 degrees Fahrenheit.

Key Features:

Multi-Channel Output: With 16 digital output channels, it can control 16 discrete devices such as relays, contactors, indicators, etc. at the same time, which is widely used in machine control, process control, building automation and other fields.

Analog signal processing: some models also have 4 analog inputs and 2 analog output channels, which can be used to collect analog signals (such as temperature, pressure, etc.) and output analog control signals to achieve more complex control functions.

Hot-plugging function: It supports hot-plugging, i.e., modules can be directly inserted or pulled out during system operation without turning off the system power, which is convenient for maintenance and replacement of modules and reduces downtime.

Resistor isolation: With resistor isolation function, it can effectively prevent the influence of external electrical interference on the module and control system, improve the stability and reliability of the system, and at the same time, it can also avoid the damage of module failure on external equipment.

Status indication: Usually with status indication function, the output status of each channel can be displayed through the indicator, which is convenient for the operator to understand the working condition of the module intuitively and quickly troubleshooting.

Weight specification: about 0.25kg to 0.5kg. Different data show a slight difference, such as some data show that its weight is 0.5 pounds (about 0.227 kg), and some data show that it weighs 0.261 kg or 250 grams.
