The Allen-Bradley 1756-OB8 is a ControlLogix discrete output module. It features eight (8) 24VDC output channels in two (2) groups of four (4) channels each. Each channel delivers an output voltage range of 10–30 volts DC with a nominal signal voltage of 24 volts DC. It is compatible for use with any ControlLogix chassis and uses the 1756-TBNH and 1756-TBSH Removable Terminal Block (RTB).
The 1715-IB16D is a discrete input module that is part of Allen-Bradley’s redundant I/O system. This module features sixteen (16) discrete input channels accepting an 18–32 VDC input voltage range. This module requires the use of 1715-TASIB16D or 1715-TADIB16D terminal base assemblies. This module has a maximum slew rate of 3600 V/s and a translation time of 1/(application scan time + 10 ms) Hz.
The Allen-Bradley/Rockwell Automation 1783-US05T switch is an unmanaged type of Ethernet switch. It has been manufactured in the Allen-Bradley Stratix series of industrial switches. The 1783-US05T unmanaged Ethernet switch has 5 copper Ethernet ports and supports AC and DC operating voltages. Its AC power supply voltage rating is 20 volts AC, and its AC operating voltage range is from 10 to 24 volts AC. Likewise, the 1783-US05T unmanaged Ethernet switch's DC power supply voltage rating is 24 volts DC, and its DC operating voltage range is from 10 to 35 volts DC.
