dc (10…60V) Output Module Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices.
dc (10…60V) Output Module 3 Environment and Enclosure ATTENTION 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 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
dc (10…60V) Output Module Before You Begin Before you begin, make sure that the following decisions are made. Determining Module Placement in the I/O Chassis You can place your module in any I/O module slot of the I/O chassis, except for the extreme left slot. This slot is reserved for programmable controllers or adapters. Group your module to minimize adverse effects from radiated electrical noise and heat.
dc (10…60V) Output Module 5 Key the Backplane Place your module in any slot in the chassis except the leftmost slot, which is reserved for processors or adapters. Position keying bands in the backplane connectors to correspond to the key slots on the module. Place the keying bands: - between 10 and 12 - between 22 and 24 I/O Chassis You can change the position of these bands if subsequent system design and rewiring makes insertion of a different type of module necessary. 1.
dc (10…60V) Output Module Install the Module ATTENTION Make certain that you do not install this module into a chassis slot keyed for a 1771-IAD series D input module. Install the module and secure it in the chassis. 1. Position the module in the card guides for the chosen slot. 1771-A1B, 1771-A2B, 1771-A3B, 1771-A3B1, 1771-A4B I/O Chassis Locking Tab 2. Slide the module into the chassis and apply firm, even pressure to seat the module into its backplane connector. Card Guides 3.
dc (10…60V) Output Module 7 Connect Wiring Connect your I/O devices to the field wiring arm, 1771-WH, shipped with the module. WARNING WARNING ATTENTION When you connect or disconnect the wiring arm with field-side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

dc (10…60V) Output Module 11 Interpreting the LED Indicators The front panel of your module contains one green module active indicator, 16 red status indicators, and one red fuse blown indicator. The green module active indicator lights when the module is powered and the processor keyswitch is in RUN mode. The indicator light turns off when the processor resets the outputs.
dc (10…60V) Output Module Replace the Fuse An overload or short will cause the single onboard fuse to blow when the module output exceeds 10 A. The onboard fuse does not protect the individual output transistors. To replace the onboard fuse, do the following. 1. Turn off all power to the I/O chassis and all output device power to the field wiring arm. ATTENTION Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module.
