1794-OB8 AB Allen-Bradley PLC 24VDC 8 Current Sourcing FLEX Digital DC Output Module 1794 Series Original brand new

1794-OB8 AB PLC 24VDC 8 current sourcing FLEX Digital DC Output Module 1794 Series Original brand new

Features

Modules are available in densities ranging from 8 to 32 points.Digital I/O modules cover a wide electrical range: 120V AC: input, output and isolated input, output modules; 8 and 16 point220V AC: input and output modules; 8 and 16 point5V DC: TTL input and output modules, 16 point24V DC: input, output, and combination modules; sink or source; protected; electronically fused; diagnostic; 8, 16, and 32 point48V DC: sink input, source output modules; 16 point125V DC: sink input module; 16 pointRelay: sink/source, 8 pointIsolated inputs and outputs can be used in applications such as motor control centers, where individual control transformers are used.Protected (P) outputs have electronic protection, which acts to shut the module down in reaction to a short circuit, overload, or over-temperature condition. Recovery from shutdown is automatic upon removal of the output fault. No fault status is provided to the processor.Electronic fused (EP) module acts to open the output when a fault occurs. The "fuse" can be reset by operating a pushbutton, via software, or by cycling the input power. Fault status is provided to the processor.Diagnostic (D) modules detect, indicate, and report the following faults: open input or output field devices or wiringshorted output field devicesshorted input or output wiringreverse polarity of user supply wiringSelectable input filter times from <1…60 ms.LED for each channel indicating status of: corresponding input deviceoutput signalConformal coated (K) versions of standard modules.Extreme environment (XT) versions of standard modules.
