Description
This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664–1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance. This equipment is supplied as “open type” equipment.
I/O Module Groups Each module condenses 2 full module groups (32 outputs) into each I/O chassis slot. For example: Module group 1 = outputs 00 through 17 Module group 2 = outputs 00 through 17 (module group 2 represents the second set of outputs). In Figure 1, terminals 1 through 20 represent module group 1. Terminals 21 through 40 represent module group 2. Terminals 10, 20, 30 and 40 are DC common and terminals 1, 11, 21 and 31 are DC power. Figure 1 Connection Diagram for the 1771OBN DC Output Module
The controller or I/O chassis power supply, connected through the backplane of the I/O chassis, powers the logic circuitry of the output modules. The maximum current drawn from this supply is 330mA. To calculate the requirements for the backplane power supply, add 330mA to the power requirements of all other modules in the I/O chassis. Calculating the requirements will prevent an overload to the chassis backplane and/or backplane power supply.
The 1771–OBN module is a modular component of the 1771 I/O system requiring a properly installed system chassis. Refer to publication 1771–IN075 for detailed information on acceptable chassis, proper installation and grounding requirements. Limi

The module has 32 status indicators on the module front plate. These represent the control status of the outputs. Each indicator is lit when its corresponding output is energized. An additional indicator is provided to indicate a blown fuse condition 1. Turn off power to the chassis. 2. Remove the module from the I/O chassis. 3. Remove the blown fuse from the fuse holder (accessible through the side cover), and replace with a 4A, 250V normal blow fuse. 4. Reinsert the module into chassis I/O chassis. 5. Turn on power to the chassis
