　　Product Description

　　The 1771-OBDS A-B digital output module is a module in the 1771 I/O series that can output digital signals to external devices.This module has 8 output channels,each channel can provide 2A output current,supports positive/negative logic output,photoelectric isolation,strong anti-interference ability,and short circuit protection.

　　The 1771-OBDS digital output module is a current limiting output module that operates on DC voltage.It is manufactured by Allen Bradley/Rockwell Automation in the PLC 5 series.The 1771-OBDS current limiting digital output module has 16 outputs,with a voltage range of 10 to 60 V DC and a working voltage range of 10 to 40 V DC.The digital output module does not have a casing,but has a conformal coating to prevent corrosion and liquids.The 1771-OBDS current limiting digital output module is designed to resist ESD or electrostatic discharge and can withstand 4 kV contact discharge and 8 kV air discharge.

　　Allen Bradley 1771-OBDS is a DC current limiting output module with 16 outputs.Its maximum conduction state voltage drop is 1.5 volts,and the maximum cutoff state leakage current of each output is 0.5 mA.

　　The maximum power consumption of 1771-OBDS is 14 watts and the minimum is 2 watts;The maximum heat dissipation is 47.8 BTU/hour,and the minimum value is 6.9 BTU/hour.

　　The operating temperature of the device is 0 to 60 degrees Celsius(32 to 140 degrees Fahrenheit),and the non operating temperature is-40 to 85 degrees Celsius(-40 to 185 degrees Fahrenheit),which can withstand many different conditions.In addition,the relative humidity of this machine can usually be maintained between 5%and 95%without condensation.

　　The isolation voltage of this module has been tested to withstand 500 volts for 60 seconds,and its ESD immunity is 4 kV contact discharge and 8 kV air discharge.

　　1771-OBDS is provided as an open device,suitable for industrial environments that do not exceed pollution 2(as defined in EN/IEC 0664-1)when applied in Zone 2 environments;In addition,the casing can only be operated through the device.After checking the fuse,check the on-site wiring arm to ensure it is securely in place.Perform this operation before checking the status of other indicator lights.

　　The 1771-OBDS A-B digital output module adopts a modular design,which is easy to install.There are 8 output indicator lights on the front panel of the module,which are used to indicate the status of the output channel.
