Parameter information: 1756-OBV8S ControlLogix discrete output module for electrical operation under DC voltage

Allen Bradley 1756-OB8 is a ControlLogix discrete output module. The output voltage range provided by this module is 10-30 VDC, with a nominal value of 24VDC. It is used to excite electrical loads and AC loads operating at DC voltage, and is used in conjunction with plug-in circuits.

1756-OB8 is a single slot module that can occupy any available slot in the chassis, except for the slot on the far left for the ControlLogix processor or ControlLogixi communication adapter/scanner module. It can serve as both a local/O component and a part of a distributed/O system. It can be installed on any available 1756-Controllogix chassis and run together with standard or power modules.

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

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

It is input into the hardware configuration, where module parameters and properties can be further modified. Some of these parameters are Request Packet Interval (RPI), Filter Time, Module Inhibit, and many other parameters. This module uses a detachable terminal block (RTB), which can be 1756-TBNH or 1756-TBSH (2-pin RTB). This module has the following available communication formats: framework optimization, listen only framework optimization, output data, listen only output data, and predetermined output data. The 1756-OB8 module also provides pilot tasks.

The voltage category of the 1756-OB8 module is 12/24 V DC power supply, with a working range of 10 to 30 V DC. Its current consumption is 165 mA at 5.1N and 2 mA at 24V. Its backplane power is 0.89W, with a maximum power consumption of 2.5W and heat dissipation of 8.53 BTU/hr at 60 degrees Celsius (140 degrees Fahrenheit). The maximum off state leakage current of this module is 1 mA per point. In the on state, the maximum voltage drop is 1.2V DC and the current is 2A. At 60 degrees Celsius, the maximum current at each point is 2A, and the maximum current for each module at 60 degrees Celsius is 8A. The surge current at each point is 4A, lasting for 10 ms, and can be repeated every 1 second at 60 degrees Celsius. The 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 status and program mode status of each point. The options for both are "Keep Last", "On", or "Off", which are set to "Off" by default. The temperature range of the 1756-OB8 module during operation is 0O to 60 degrees Celsius, and it is -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%.
