Product Details

The AB 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. It comes with a 2-key switch position, 8 on the left and 2 in the right. The AB 1734-OB8S Series A module has 8 outputs per module and is a current sourcing type of module. The 1734-OB8S output point has a current of 1A at most. Its pulse width is 475 μs 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.
