Publication 1746-2.35 6 Discrete Input and Output Modules I/O Module Operation Power Supply Requirements Discrete modules receive power through the 1746 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. Input Modules An input module responds to an input signal in the following manner: 1. 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. All input modules use input filtering. 2. Optical isolation shields backplane circuits and module logic circuits from possible damage due to electrical transients. 3. Logic circuits process the signal. 4. An input LED turns on or off indicating the status of the corresponding input device. Input Optical Logic Circuits Backplane Input Filtering Isolation LED Output Modules An output module controls the output signal in the following manner: 1. Logic circuits determine the output status. 2. An output LED indicates the status of the output signal. 3. Optical isolation separates module logic and backplane circuits from the field signal. 4. The output driver turns the corresponding output on or off. Logic Optical Backplane Output Drivers Output Circuits Isolation LED Publication 1746-2.35 Discrete Input and Output Modules 7 Surge Suppression Most output modules have built-in surge suppression to reduce the effects of high-voltage transients. However, 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 Additional suppression is especially important if your inductive device 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 will reduce the effects of voltage transients caused by interrupting the current to that inductive device and prolong the life of the switch contacts. The diagram below shows an output module with a suppression device. + DC or L1 VAC/VDC Snubber OUT 0 OUT 1 OUT 2 AC or DC OUT 3 Output Module OUT 4 OUT 5 OUT 6 OUT 7 COM DC COM or L2 Recommended surge suppressors are provided in the specifications tables. Important: Adding a suppression device across your load will defeat the fast turn-off feature of the 1746-OB16E Series B and later, -OBP8 Series B and later, -OBP16, and -OVP16 DC output modules. Refer to pages 29, 32, and 37 for more information about suppression when using the 1746-OB16E, -OBP8, -OBP16, and -OVP16, respectively.

When used with an SLC 5/03� or higher processor and the Discrete Input Interrupt (DII) instruction (100 �sec polling), pulses can be read up to a frequency of 1K Hz. (It is 2K Hz if the input signals are from a gray code encoder.) Recommended wiring to an Allen-Bradley 845D Absolute Gray Code Encoder is provided on page 27. Both sinking and sourcing versions of the fast response input module are available. High-Current Solid-State Output Modules (1746-OBP8, -OAP12, -OBP16, -OVP16).B High-current solid-state output modules expand application coverage for the SLC 500 by providing the following enhanced functionality: • increased current rating • fuse protection and diagnostics • high-speed switching • excellent reliability The high current solid state output modules expand application coverage in automotive, packaging, and material handling applications by allowing the SLC 500 processor to directly control solenoids, contactors, motors, and motor starter loads (up to size 5) with continuous current requirements of up to 1A at 60�C (1746-OAP12, -OBP16, -OVP16) and 2.0A at 60�C (1746-OBP8). 1746-OAP12, -OBP16, and -OVP16 modules also provide fuse protection and blown fuse diagnostics for increased up-time. The ac output module includes two replaceable fuses (one per common), which protect the module in the event of short circuits. 1746-OBP16 and -OVP16 output modules include a replaceable fuse on the common providing short circuit protection for wiring (16 AWG or larger) to external loads. A jumper can be set on these modules to provide CPU notification and system shutdown if the module fuse blows. The modules also include a blown fuse LED to assist I/O troubleshooting. Inductive load turn-off time for 1746-OBP8 (Series B and later), -OBP16 and -OVP16 DC output modules is reduced by 70% over standard 1746 DC output modules allowing fast application cycle times.

The protection is based on a thermal cut-out principle. In the event of a short circuit or overload on an output channel, that channel limits the current within milliseconds after its thermal cut-out temperature has been reached. All other channels continue to operate as directed by the processor. The 1746-OB16E lowers maintenance costs by eliminating the need to replace damaged modules and blown fuses. After the short circuit or overload condition is corrected, restore power and the module automatically resets and resumes control of the output channel. The 1746-OB16E provides a broad voltage range of 10 to 30V dc and a current rating of 1A at 30�C and 0.5A at 60�C making it the perfect solution for controlling 12V dc and 24V dc solenoid and lamp loads. The module is also equipped with an LED indicator that illuminates when the short circuit or overload condition occurs to expedite the troubleshooting process. Inductive load turn-off time for 1746-OB16E (Series B and later), output module is reduced by 70% over standard 1746 DC output modules allowing fast application cycle times. OUTPUT E F EFUSE LED U S E NOTE: There is Front View no jumper setting on this module. Important: The module does not provide protection against reverse polarity wiring or wiring to AC power sources. Electronic protection is not intended to replace fuses, circuit breakers, or other code-required wiring protection devices. Publication 1746-2.35 12 Discrete Input and Output Modules 1746-OB16E Overload Protection The chart below describes overload protection for the 1746-OB16E. The electronic protection is based on a thermal cut-out temperature, which is reached more quickly (at lower overload current) when two to four adjacent channels are operating. The adjacent channel groupings are 0–3, 4–7, 8–11, and 12–15. 6 ÉÉÉÉÉÉÉÉÉÉÉÉÉÉÉ ÉÉÉÉÉÉÉÉÉÉÉÉÉÉÉ Overload Protection ÉÉÉÉÉÉÉÉÉÉÉÉÉÉÉ 5 (Single channel operating at maximum rated current.)
