Product description:
The Allen-Bradley 1771-OB is a DC output module that provides eight individually fused outputs to drive DC loads. It is designed for use with Allen-Bradley 1771 I/O chassis and is compatible with a variety of DC loads, including solenoids, relays, and motors.
Product parameters:
- Input voltage range: 10 to 27V dc
- Output voltage range: 12 to 24V dc
- Output current: 1.5A per output (not to exceed 8A per module)
- Surge current: 4A for 1ms, repeatable every 1 second
- Off-state leakage current: 1mA per output
- On-state voltage drop: 2V dc (maximum)
- Turn-on/turn-off delay times: 10ms
- Power dissipation: 16.9 Watts (max.), 0.9 Watts (min.)
- Thermal dissipation: 57.6 BTU/hr (max.), 3.0 BTU/hr (min.)
- Backplane current: 165mA @ 5V dc +5%
- Opto-electrical isolation: 1500V ac (RMS)
Usage method:
The Allen-Bradley 1771-OB DC output module is installed in an Allen-Bradley 1771 I/O chassis. The chassis provides power to the module and connects it to the PLC. The module’s output terminals are connected to the DC loads that need to be controlled.
To use the module, the outputs must be configured in the PLC program. The PLC program will determine which outputs are turned on and off, and for how long.
Product application:
The Allen-Bradley 1771-OB DC output module is used in a variety of industrial applications, including:
- Machine control
- Process control
- Robotics
- Material handling
- Lighting control
- HVAC control
Example application:
The Allen-Bradley 1771-OB DC output module can be used to control the solenoids on a pneumatic valve manifold. The PLC program can be used to turn on and off the solenoids in a specific sequence to control the movement of the pneumatic actuators.
The Allen-Bradley 1771-OB DC output module is a versatile and reliable module that can be used to control a variety of DC loads in a wide range of industrial applications.
