Product Description
The Allen-Bradley 1771-OBD is a 16-point digital output module for PLC 5 controllers. It has a 10-60 VDC output voltage range and can provide up to 2 amps per output or 8 amps total for the module. The 1771-OBD is also pilot duty rated for 0.2 amps per output.
Product Parameters
- Output voltage range: 10-60 VDC
- Output current: 2 amps per output, 8 amps total
- Pilot duty output current: 0.2 amps per output
- Number of outputs: 16
- Dimensions: 6.3″ x 3.5″ x 1.2″ (160mm x 89mm x 30mm)
- Weight: 1.5 lbs (0.7 kg)
Usage Method
The 1771-OBD is installed in a PLC 5 chassis and wired to the output devices that it will control. Once it is installed and wired, the 1771-OBD can be programmed using the PLC 5 programming software.
Product Application
The 1771-OBD is a versatile output module that can be used to control a wide variety of devices, such as:
- Motor starters
- Solenoids
- Relays
- Pilot lights
- Annunciators
- Other digital output devices
The 1771-OBD is commonly used in industrial automation applications, such as:
- Manufacturing
- Material handling
- Process control
- Building automation
Example Application
The 1771-OBD could be used to control the operation of a conveyor belt system. The module could be programmed to turn on and off the conveyor belt motor, as well as the start and stop buttons. The 1771-OBD could also be used to control the pilot lights that indicate the status of the conveyor belt system.
