GuardPLC Digital 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://www.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices.
GuardPLC Digital Output Module 3 About the Module The 1753-OB16 digital output module is a 16-channel output module for use with GuardPLC controllers.
GuardPLC Digital Output Module 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 11.
GuardPLC Digital Output Module 5 Mount the Module IMPORTANT For effective cooling, mount the module following these guidelines. • • • • Mount the module horizontally. Provide a gap of at least 100 mm (3.94 in.) above and below the module. Select a location where air flows freely or use an additional fan. Do not mount the module over a heating device. The module cannot be panel-mounted. Mount the module to a DIN rail by following these steps. 1. Hook the top slot over the DIN rail. 2.
GuardPLC Digital Output Module Wire the Module The following sections describe how to connect the voltage supply and connect the inputs and outputs. Connect the Voltage Supply To comply with CE Low Voltage Directives (LVD) and UL restrictions, you must use either a Safety Extra Low Voltage (SELV), or a Protected Extra Low Voltage (PELV) power supply to power this module. A SELV supply cannot exceed 30V rms, 42.4V peak, or 60V DC under normal conditions and under single-fault conditions.
GuardPLC Digital Output Module 7 Safety-related Digital Outputs The module has 16 digital outputs (DO1…DO16) whose status is indicated via status indicators. An output is in a safe state when it is de-energized. If a fault occurs, all outputs are turned off. Each of the 16 outputs can have a load of 1 A at the ambient temperature of 60 °C (140 °F) or up to 2 A at a maximum temperature of 40 °C (104 °F).

GuardPLC Digital Output Module 9 Make Connections for Safety-Related Communication The module has two 10/100BaseT, RJ45 connectors on the bottom of the unit, that provide communication to the GuardPLC controller via GuardPLC Ethernet protocol. Because this is an Ethernet switch, you can daisy-chain connections from the GuardPLC module to other distributed I/O modules. The switch is auto-detect. Either crossover or straight-through cabling can be used. Star or line configurations are available.
GuardPLC Digital Output Module Status Indicators Indicator State Condition 24V DC On 24V DC operating voltage present. Off No operating voltage. On This is the normal status of the controller. A routine, which has been loaded into the controller, is executed. The controller processes input and output signals, carries out communication, and performs hardware and software tests. Flashing The controller is in STOP mode and is not executing a routine. All system outputs are reset.
