Allen-Bradley 1746-OB8 SLC 500 8-Channel DC Output Module (Sourcing)

Current Sourcing DC Output Module

The Allen-Bradley 1746-OB8 is a DC output module that has 8 outputs but no inputs. It has a voltage category of 24V DC in signal output and its number of points per common is 8. It has a total heat dissipation of 6.9 W and a maximum signal delay of 1A and 8A at 30°C and 0.5A and 4A at 60°C, respectively. Moreover, the maximum off-state leakage of this module is 1mA and the maximum thermal dissipation is 6.9 W. The 1746-OB8 has a maximum On-state voltage drop of 1.2V at 1A and 3A for 10ms maximum surge current per point. It has a backplane current consumption of 135mA at 5V DC and 0 mA at 24V DC. It has minimum load current of 1 mA. Please watch out for transient pulses which can occur when the external DC supply voltage is applied to the output common terminals. Please refer to the user manual for more information about transient pulses. The 1746-OB8 has a design that complies with international standards. It is UL-listed, CE compliant, and CSA and C-Tick certified. It has an operating humidity that ranges from 5 – 95% (non-condensing).

 

1. Discrete control of industrial equipment: The 8-channel relay output of 1746-OB8 is suitable for the actuator control of small and medium-sized automation equipment, such as solenoid valves, contactors, and small motor start and stop. In packaging machinery, assembly lines and other scenarios, the action sequence of each station can be accurately controlled to improve the operation efficiency of the equipment.
2. Traditional electrical system transformation: This module is often used to replace the old relay control cabinet, simplify the circuit complexity and enhance programmability. For example, in the machine tool automation upgrade project, while retaining the original 24V actuator, flexible logic control is achieved through PLC, and the transformation cost is reduced by more than 40%.
3. Safety interlock and alarm system: The physical isolation characteristics of the relay output make it suitable for safety circuit control, such as emergency stop circuit, alarm indicator light drive, etc. In the environmental protection equipment monitoring system, the module can be linked to the sound and light alarm device to ensure timely response to abnormal conditions.
