GuardPLC Digital Input/Output Module 3 About the Module The 1753-IB20XOB8 digital input/output module is a 28-channel (20 inputs/8 outputs) module for use with GuardPLC controllers.
GuardPLC Digital Input/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 Input/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 the steps below. 1. Hook the top slot over the DIN rail. 2.
GuardPLC Digital Input/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 Input/Output Module 7 Safety-related Digital Inputs The module has 20 digital inputs (DI1…DI20) whose status is indicated via status indicators. LS+ is a voltage source that provides 24V DC for a group of four dry contact inputs. There are five groups on the module.
GuardPLC Digital Input/Output Module Devices with their own dedicated power supply can also be connected. Connect the reference pole of the external power supply to the L- reference pole of the input.

GuardPLC Digital Input/Output Module Line Control Line control is a short-circuit and line-break monitoring system, for example, E-stop inputs that can be configured for the GuardPLC system. Up to eight digital outputs (DO1…DO8) can be configured as pulsed outputs. The example below shows two pulse outputs connected to the digital inputs (DI) of the same system. As a result, the connections to the digital inputs (DI) are monitored.

See the terminal torque specifications on page 14. Digital outputs (DO) are connected to these terminals.
GuardPLC Digital Input/Output Module 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 Input/Output Module 13 Status Indicators Indicator State 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.
