AC/DC (120V) Input Module ! 3 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. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present, and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications. See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosures. Also, see the appropriate sections in this publication, as well as the Allen–Bradley publication 1770–4.1, (“Industrial Automation Wiring and Grounding Guidelines”), for additional installation requirements pertaining to this equipment. 4 AC/DC (120V) Input Module The ac/dc input module is shipped in static-shielded packaging to guard against electrostatic discharge damage. Observe the following precautions when handling the module. ATTENTION Electrostatic discharge can damage ! integrated circuits or semiconductors if you touch backplane connector pins. Follow these guidelines when you handle the module: • Touch a grounded object to discharge static potential • Wear an approved wrist-strap grounding device • Do not touch the backplane connector or connector pins • Do not touch circuit components inside the module • If available, use a static-safe work station • When not in use, keep the module in its original static-shielded packaging The 1771-IAD Series D module is compatible with all chassis except the 1771-A1, 1771-A2 and 1771-A4 chassis. Make sure no other input module or single card block transfer module is placed in the same module group when using 2-slot addressing. Any discrete output module may be used within the same module group. Your module receives its power through the 1771 I/O chassis backplane from the chassis power supply. The module requires 195mA from the output of this supply. Add this to the requirements of all other modules in the I/O chassis to prevent overloading the chassis backplane and/or chassis power supply. AC/DC (120V) Input Module Setting the Delay Time Jumper 5 Your module is equipped with an adjustable delay time jumper. Use the jumper to select between two input channel delay times. The delay time you choose applies to all sixteen of the module’s channels. Use this delay time: If you want: (. /* !/!/ /3+%' %)+0/ -! %)#. (. /* +-!1!)/ !/!/%*) *" "'.! %)+0/. %) $%#$4)*%.! !)1%-*)(!)/. The module is shipped with the delay time jumper preset to 5ms. To change the delay time jumper to 20ms, do the following: 1. Locate the delay time jumper selection plug at the top-right edge of the module circuit board, as shown in the following figure. *+4-%#$/ ! #! *" %-0%/ *- (. (. !'3 %(! 0(+!.$*2) %) +-!.!/ (. +*.%/%*) 2. Use your finger to slide the jumper off the 5ms position (the middle post and the right post). 3.

When you insert or remove the module while backplane power is on, or you connect or disconnect the wiring arm with field power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure power is removed or the area is nonhazardous before proceeding. The 1771–IAD 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.
