The 5094-OW4IS module is an output module from Allen-Bradley/Rockwell Automation. This safety digital relay output module is available through the FLEX 5000 series that offers multiple components in order to meet the requirements of different applications. The 5094-OW4IS module has an open enclosure and the T4 temperature code (ATEX, IECEx, North American). The module is tested for operation on a temperature range of -40 to 70 degrees Celsius (-40 to 158 degrees Fahrenheit) and it can be stored in temperature ranges from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The 5094-OW4IS module features an off-state leakage of 0 milliAmps and it does not include onboard snubbers. The module has a maximum output delay time of 20 milliseconds off to on and of 10 milliseconds on to off. The safety reaction time (SRT) of the module is 20 milliseconds. In addition to that, the mean bounce time is 1 millisecond.

The Allen-Bradley 5094-OW4IS module features output control in fault state per point and it supports different output states. The minimum load current of the module is 1 milliAmp. The specified contact life is 100K cycles at a resistive load of 2 Amps / 50K cycles at a resistive load of 4 Amps. The 5094-OW4IS module has 4 Form A outputs that are normally open and an output voltage range of 5 to 125 Volts DC or 5 to 240 Volts AC. The backplane power (BP) voltage rating is 15 Volts DC and the maximum backplane power (BP) current rating is 100 milliAmps. The voltage range of the sensor-actuator power (SA) is  from18 to 32 Volts DC and the maximum current rating of the sensor-actuator power (SA) 125 milliAmps.
