SLC 500 Digital I/O Modules 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://www.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices.

SLC 500 Digital I/O Modules 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 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is not intended for use in residential environments and may not provide adequate protection to radio communication services in such environments. This equipment is supplied as open-type equipment.

SLC 500 Digital I/O Modules 5 Install and Remove the Module ATTENTION: Never install, remove, or wire modules with power applied to chassis. IMPORTANT The first slot of the chassis is reserved for the processor or the 1747-ASB module. Follow these steps to install the module: 1. Disconnect power. Module Installation 2. Align the circuit board of module with the chassis card guide. (A) 3. Slide the module into the chassis until the bottom tabs lock into place. (B) B 4.

SLC 500 Digital I/O Modules Octal Label Kit Installation (for PLC processors only) The octal label kit consists of an octal filter label and a door label. Use these octal labels to replace the decimal labels that are attached to the I/O modules. TIP The octal label kit can be obtained from your Allen-Bradley distributor. The octal kit is ordered based on the catalog number of the I/O module.

SLC 500 Digital I/O Modules Fuse Protection (1746-OAP12 modules) A fuse is provided on each common of the 1746-OAP12 module (shown on Location of Jumpers and Fuses for 1746-OAP12 Module on page 10) for a total of two fuses. The fuses are designed to protect the module from short-circuit conditions. The fuse does not provide overload protection. In the event of an overload on an output channel, it is likely that the fuse will not blow and the output device associated with that channel will be damaged.

Processor is notified when fuse is blown. 1746-OAP12 JP1 IMPORTANT When using SLC 5/02 processor and later processors, a user-fault routine cannot be used to clear the major fault bit. ATTENTION: For 1746-OBP16 and 1746-OVP16 modules, all outputs on the module are OFF if the fuse blows.

SLC 500 Digital I/O Modules 13 The following table defines operation of all SLC 500 processors in the case of a blown fuse in 1746-OBP16, 1746-OVP16, and 1746-OAP12 modules. Processor Operation After a Blown Fuse (1746-OBP16, 1746-OVP16, and 1746-OAP12 modules) JP1 Set to Processor Continues JP1 Set to Processor Faults No error. Processor continues with 1746-OBP16 and 1746-OVP16 outputs de-energized. 1746-OAP12 outputs, on the same common as the blown fuse, are de-energized. Nonrecoverable error.

SLC 500 Digital I/O Modules Replace Fuses ATTENTION: Never install, remove, or wire modules with power applied to chassis. 1. Remove SLC 500 system power and correct the conditions causing the short circuit. 2. Remove the output module from the chassis. 3. Remove the fuse. • 1746-OBP16 and 1746-OVP16 modules: Use a wide-tipped, slotted-head screwdriver to remove the blown fuse. Slide the screwdriver tip under the fuse and use a twisting motion to pry the fuse from the fuse clip.

Front View Auto Reset Operation IMPORTANT The 1746-OB6EI and 1746-OB16E modules perform auto-reset under overload conditions. When an output channel overload occurs, that channel will limit current within milliseconds after its thermal cut-out temperature has been reached.
PAGE 16
SLC 500 Digital I/O Modules Recovery from Channel Shutdown 1. Remove the SLC 500 system power and correct the conditions causing the short circuit or overload current condition. 2. Restore the SLC 500 system power. The module automatically resets and resumes control of the output channel and associated load.

SLC 500 Digital I/O Modules ATTENTION: A transient pulse occurs in transistor outputs when the external DC supply voltage is applied to the output common terminals (for example, via the master control relay). This can occur regardless of the processor having power or not. For most applications, the energy of this pulse is not sufficient to energize the load.

SLC 500 Digital I/O Modules 41 (8) Fast turn-off modules (1746-OB6EI, 1746-OBP8 series B and later, 1746-OB16E series B and later, 1746-OBP16, and 1746-OVP16) provide fast OFF delay for inductive loads. Comparative OFF delay times for 1746-OB8/1746-OV8 and fast turn-off modules; when switching Bulletin 100-B110 (24Ws sealed) contactor, are: 1746-OB8/1746-OV8 OFF delay = 152 ms; fast turn-off modules OFF delay = 47 ms.

SLC 500 Digital I/O Modules ATTENTION: To avoid potential damage to TTL modules, handle them by the ends of the module, not metallic surfaces. Electrostatic discharges can damage the module. Take care to prevent exposure of terminals or components to electrostatic charges. Careful wire routing within the enclosure helps cut down electrical noise between I/O lines. Refer to the SLC 500 Modular Hardware Style User Manual, publication 1747-UM011, for recommended wiring procedures for TTL modules.
