About 1734-OB8S

The Allen-Bradley 1734-OB8S POINT Safety Output Module has solid-state outputs and comes in 2 series (A and B.) It has a dual-channel mode that will control any redundancy using 2 output signals. The Allen-Bradley 1734-OB8S Series has Eight (8) Current sourcing outputs per module. The 1734-OB8S output has an output current of 1A per channel. Its pulse width is 475 micro/s with a pulse period of 575 milliseconds. It has a maximum field capacitance limit per output of 950 nF. Its voltage drop reaches 0.165 Volts and it has a current leakage of 0.1 mA at most. The 1734-OB8S has short-circuited detection with a category of short, high, low, and cross-circuit fault detection. The short-circuit is electronically protected and its output can aggregate a current of 8A.

The 1734-OB8S’s reaction time is up to 6.2 milliseconds and its point-bus current reaches up to 190 mA. Its power dissipation is 4.5 Watts maximum and 3.02 Watts typical. It has a thermal dissipation of 15.38 BTU/hour. Its isolation voltage is 50 Volts continuous with basic insulation between the field side and the system. There is no isolation between individual channels. The 1734-OB8S has been tested at 707 Volts DC for 60 seconds. It has a power bus operating supply voltage of 24 Volts DC nominal and a voltage range of 19.2 to 28.8 Volts DC. When there is no load, it has a power-bus current of 75 mA. It comes with a variety of indicator lights, 1 yellow for lock status, 1 green/yellow for power status, and 8 I/O for the channel. The 1734-OB8S has a wiring category of 2-on signal ports. The wiring size and terminal block torque can only be determined by an installed terminal block. The 1734-OB8S has dimensions of 77 x 25 x 55 millimeters.

The 1734-OB8S has a 50 mA max power bus current when it has no load connected. For both series of the Allen-Bradley 1734-OB8S, the operating temperature is -20 to 55 degrees Celsius and the storage temperature is -40 to 85 degrees Celsius. It has a relative humidity of 5 to 95% non-condensing, a vibration of 5 G at 500 Hertz, an operating shock of 30 G, and a non-operating of 50 G. It meets the following requirements: SIL CL2, PLe, Category 4. This safety module is compatible with GuardLogix, Compact GuardLogix, and SmartGuard Controllers. When configuring this 1734-OB8S module, use the RSNetWorx for DeviceNet software. If, however, you are using an Ethernet network, the GuardLogix programming tool and the Logix Designer application are best when configuring the 1734-OB8S POINT Safety Output Module. This Safety I/O Module weighs 2.2 ounces.

The 1734-OB8S is an Allen-Bradley Module that belongs to the POINT Guard IO Safety Module. This module has Solid-State outputs capable of being operated in single channel or dual channel mode.

The Single-Channel mode uses one output signal for providing control. Under this mode, the module is qualified for use in applications that require Safety Category 2 and rated up to including performance Level d / SIL CL2 when the Point Mode configuration of the channels are configured for Safety Pulse Test. The 1734-OB8S single channel mode is approved for use in safety applications not less than 600 ms process safety times. It may also be used in applications with demand rates not more than 1 demand per minute.

The Dual-Channel Channel mode uses both output channels which enables redundant control for use in applications that require Safety Category of 3 and 4 and rated up to including performance Level e / SIL CL3 when the Point Mode configuration of the channels are configured for Safety Pulse Test.

The 1734-OB8S safety outputs is capable of being pulse-tested for detection of field wiring short circuits.

When the module has detected fault, the outputs are switched OFF and will remain off until the module has recovered from the detected fault. To enable the safety output active, the cause of the error must be removed, Command the safety output to switch to the safe state or allow the output-error time to expire. The module’s fault recovery is conformed once the indicator’s RED light turns off.
