1771 Digital I/O DC Input and Output Modules Product Data Interfaces your ON/OFF devices to AllenBradley programmable controllers within the 1771 Universal I/O structure. Allen-Bradley digital dc I/O modules interface to ON/OFF devices such as limit switches, pushbuttons, motor starters, pilot lights, and annunciators. These modules are compatible with all current Allen-Bradley programmable controllers. This saves on spare parts, system engineering, inventory, and training costs. Supports highpower operations. The dc solid-state family of digital I/O modules meets requirements for applications from 5-125V dc. These modules exhibit long life (20-100+ million operations). Provides system protection and troubleshooting aids. The dc I/O modules include electrical-optical isolation and filter circuits for signal noise reduction. To help you troubleshoot your system, module indicators are provided to show input or output status and fuse-blown conditions. Publication 17712.180 - July 1996 2 1771 Digital I/O DC Input and Output Modules Overview Understanding Digital I/O Allen-Bradley offers a digital I/O product line consisting of three families: Modules Family Document AC Digital Input and Output Modules 1771-2.182 DC Digital Input and Output Modules 1771-2.180 Digital Relay Contact Output Modules 1771-2.181 System Compatibility Individual dc input and output module specification sheets show compatibility and use of the data table for each. Status Indicators The front panel of each digital I/O dc module contains status indicators. Each status indicator shows the ON/OFF condition of an individual input or output. Some modules have an additional indicator, such as Fuse-Blown. Refer to the individual module specification sheets for more information. Keying Plastic keying bands shipped with each I/O chassis allow you to key your I/O slots to accept only one type of module. You can key any backplane connector in an I/O chassis to receive your module except for the leftmost connector, which is reserved for adapter or processor modules. Power Supply Requirements Digital modules receive power through the 1771 I/O chassis backplane from the associated chassis power supply. Refer to the individual module specifications for the current required from the power supply (in mA) to operate the module. You should total the current requirements for all the modules in the chassis to avoid overloading the power supply or the I/O chassis backplane. Module Placement Guidelines Group your modules to minimize adverse effects from radiated electrical noise and/or heat. • Group analog input and low voltage dc modules away from ac modules or high voltage dc modules to minimize electrical noise interference. • Place analog input modules and other I/O modules that are sensitive to heat away from slot power supplies to minimize adverse heat effects. Publication 17712.180 - July 1996 1771 Digital I/O DC Input and Output Modules 3 Overview Addressing Modes Your Allen-Bradley processor can address its I/O in 2-slot, 1-slot or 1/2-slot I/O groups. You select the addressing method for the chassis in which a processor or I/O adapter resides with the I/O chassis backplane switch assembly. You make the selection for each chassis independently, choosing one method of addressing for each chassis. Fault Mode Selection Some digital dc modules let you select last state or reset for input or output failure configuration. You select one of the two options by positioning a configuration plug (jumper) on the edge of the printed circuit board. This plug is independent of the last state switch on the I/O chassis backplane. When the input module detects a fault, it’s input-image bits are put into the state indicated by the jumper position. When the output module detects a fault it’s outputs are put into the state indicated by the jumper position. Refer to the Table below for the state of inputs or outputs after a module detects a fault and jumper settings. Jumper Settings and the State of Inputs or Outputs If you want module inputs and outputs to: Set jumper to: Stay in their last state when a module last state detects a fault (LS) Reset to off when a module detects a fault reset For instructions on how to set the configuration jumper on those modules that allow you to select the fault mode, refer to the individual module specification sheets. DC Input Modules 1771 digital dc input modules convert dc signals from user devices to the appropriate logic level for use within the processor. Typical input devices include: • proximity switches • limit switches • selector switches • float switches • pushbutton switches Allen-Bradley dc input modules are available with a wide range of input terminals per module. The table below lists the Allen-Bradley dc digital input modules. It also shows the image bits per module and addressing modes you can use with the I/O chassis and chassis compatibility for each input module.

N = Not compatible Input Filtering Input filtering limits the effect of voltage transients caused by contact bounce and/or electrical noise. If not filtered, voltage transients could produce false data. Backplane circuits, module logic circuits, and the rest of the system are protected from possible damage due to electrical transients by opto-electrical isolation. Certain modules allow you to set input filter time jumpers. Refer to the individual module specifications for more information.

N = Not compatible Publication 17712.180 - July 1996 6 1771 Digital I/O DC Input and Output Modules Overview Surge Suppression Most output modules have internal clamping diodes to protect the output transistors from high voltage transients. Important: We recommend that you use an additional suppression device if an output module is being used to control an inductive device such as: • relays • motor starters • solenoids • motors and is in series with or parallel to a “hard contact” such as: • pushbuttons • selector switches By adding a suppression device directly across the coil of an inductive device, you’ll prolong the life of the switch contacts. The diagram below shows an output module with a suppression device. +dc snubber A O 1 2 3 4 5 6 7 12346-I B The most important factor in selecting a suppression device is the impedance characteristic. Thus, no single suppression device can be recommended for every possible load. Fuses The outputs on most modules are fused to protect module circuitry from overload. Some module outputs are individually fused and some modules have one fuse for all module circuits. Fused Wiring Arm Information The optional Fused Wiring Arm (1771-WHF or -WHFB) provides fuse protection for each output. It also allows simple fuse replacement without removing the wiring arm from the I/O chassis. You can use this wiring arm as an alternative to the 1771-WH Wiring Arm.
