The Allen-Bradley 1734-OB8S Safety Output Module has hard-state outputs and arrives in 2 series (A & B.) It has a dual-station mode that will control any redundancy utilizing 2 output signals. The A B 1734-OB8S Series has 8 Current sourcing outputs per unit. This 1734-OB8S output has a 1A output current per channel. Its pulsation width is 475 micro/s with a pulse period of 575 mill sec. It has a maximum field capacitor limit/output of 950 NF. Its voltage droplet ranges to 0.165 Volts & it has a current outflow of 0.1 MA at most. It has short-circuited detection with a grouping of short, low, high, and cross-circuit fault recognition. The short-circuit is electronically secured & its output can combine a current of 8A.
The Solo-Channel mode utilizes one output signal for giving control. Under the mode, the unit is qualified for utilize in applications that need Safety Category 2 & rated up to including performance Level d / SIL CL2 when this Point Mode arrangement of the channels are constructed for Safety Pulse Test. The 1734 OB8S Input Module is permitted for use in safety requests not less than 600 ms procedure safety times. It may also be utilized in applications with demand rates not higher than 1 demand per minute.
The Double-Channel mode uses both output channels that empowers redundant control for use in applications that need Safety Category of 3 & 4 and rated up to including performance level e / SIL CL3 when the Point Mode formation of the channels are organized for Safety Pulse Test.
Know About 1734-IB8S
