Product details

Basic parameters :1756-0BV8S ControlLogix Discrete output module for electrical loads operating at DC voltage as well as AC loads

The Allen-Bradley 1756-OB8 is a ControlLogx discrete output module. The module offers an output voltage range of 10-30 VDC with a nominal value of 24VDC. It is used to excite electrical loads operating at DC voltage as well as AC loads, in conjunction with the insertion circuit.

The 1756-OB8 is a single slot module that can occupy any available slot in the case except for the leftmost slot for the ControlLogix processor or the ControlLogix communication adapter/scanner module. It can be used either as a local /O component or as part of a distributed /O system. It can be installed into any available 1756-ControlLogix chassis and runs with standard or Psus.

The 1756-OB8's backplane current is 165 mA at 5.1VDC and 2 mA at 24VDC, while the total backplane power is 0.89W, the power consumption is 2.5W at 60°C(140F), and the heat dissipation is 8.53BTU/hr. Each channel of this output module provides up to 2a(60°C(140°F) and 8 a(60°C(140°F) currents per module.

The module uses a detachable patch board (RTB) to connect each channel of the module to an electrical load. The compatible RTBS are 1756-TBNH and 1756-TBSH, while the appropriate RTB keying is user-defined mechanical keying.

It is entered into the hardware configuration where module parameters and properties can be further modified/Some of these parameters are request packet interval (RP), filter time, module prohibition, and many others. The module uses a removable patch board (RTB), which can be 1756-TBNH or 1756-TBSH(20-pin RTB). The module has the following communication formats available frame optimization, listen only frame optimization, output data, listen only output data and scheduled output data. The 1756-OB8 module also provides pilot tasks.

The 1756-OB8 module has a voltage class of 12/24 volt DC power supply with an operating range of 10 to 30 volt DC. Its current consumption is 165 mA at 5.1N and 2 mA at 24V. It has a backplane power of 0.89W, a maximum power consumption of 2.5W at 60 degrees Celsius (140 degrees Fahrenheit), and a heat dissipation of 8.53 BTU/hr. The module has a maximum off state leakage current of 1 mA per point, and a maximum voltage drop of 1.2V DC and a current of 2A in the on-state. At 60 degrees Celsius, the maximum current per point is 2A, and the maximum current per module is 8 A at 60 degrees Celsius. It has a surge current of 4A per point, lasts for 10 ms, can be repeated every 1 s at 60 degrees Celsius, and its minimum load current is 2mA/ point. The isolation voltage of the module is continuously 250V. This module also allows you to modify the fault mode state for each point and the program mode state for each point. The options for both are "Keep Last," "On," or "Off." The default setting is "Off." The 1756-OB8 module has a temperature range of 0 to 60 degrees Celsius when in operation and -40 to 85 degrees Celsius when not in operation. It also has a maximum ambient air temperature of 60 degrees Celsius and a non-condensing relative humidity of 5 to 95 percent.
