Device wiring is an essential part of any automated system. Getting the wiring right is crucial for proper operation of the system. In this article, we will examine the 1734 OB8 wiring diagram.
What is 1734 OB8?
The 1734 OB8 is an output module used in Allen Bradley’s ControlLogix programmable logic controllers. It provides a high-density output solution for controlling multiple devices through a single module.
The module has eight outputs, each configurable for sourcing or sinking operation. The outputs are designed to provide high-current sink and source capability, making them suitable for a wide range of industrial applications.
The 1734 OB8 wiring diagram is an essential tool for configuring and wiring the module. The diagram provides a visual representation of the module’s wiring connections and helps to ensure proper wiring and configuration of the system.
The 1734 OB8 wiring diagram is arranged as follows:
Power Supply Wiring
The 1734 OB8 requires a 24V DC power supply. The power supply wiring involves connecting the positive and negative sides of the power supply to the module’s power terminals.
The output wiring involves connecting the load to the module’s output terminals. The module’s outputs are configured as either sourcing or sinking outputs. If the output is sourcing, the positive side of the load is connected to the output terminal. If the output is sinking, the negative side of the load is connected to the output terminal.
Each output terminal is identified by a unique number. The wiring diagram provides the wire color for each output terminal to assist in identifying the correct terminal.
The 1734 OB8 must be properly grounded to ensure proper operation of the system. The wiring diagram provides a grounding symbol to indicate where the ground wire should be connected.
Q1. What is the maximum output current for the 1734 OB8?
The maximum output current for each output of the 1734 OB8 is 2A.
Q2. Can the 1734 OB8 be used in hazardous locations?
The 1734 OB8 is not suitable for use in hazardous locations.
Q3. What is the maximum cable length between the 1734 OB8 and the load?
The maximum cable length between the 1734 OB8 and the load depends on the cable type and load current. Consult the manufacturer’s recommendations for proper cable selection and length.
Q4. Can the 1734 OB8 be used with AC loads?
No, the 1734 OB8 is designed for use with DC loads only.
Q5. What is the purpose of the onboard status indicator?
The onboard status indicator provides a visual indication of the output status of the module. The LED indicates the module’s operating status, such as power on or fault conditions.
Proper wiring and configuration of the 1734 OB8 module are critical for ensuring the reliable operation of an automated system. The 1734 OB8 wiring diagram provides a visual representation of the module’s wiring connections and helps to ensure proper installation and configuration of the system.
