The wiring connections for the 1756-IB16 module are straightforward, making it easy to integrate into your control system. The module is also designed with LED indicators that provide status information, allowing you to quickly diagnose any issues that may arise.
Wiring Diagram
The 1756-IB16 module’s wiring diagram consists of two parts: the input circuitry and the output circuitry. The input circuitry is responsible for detecting the presence or absence of a DC signal and generating an output signal based on the input signal’s condition. The output circuitry provides control signals to other devices in the system based on the input signal’s condition.
The input circuitry consists of 16 channels, each of which has two input terminals: the positive (+) and negative (-) terminals. The positive terminal is connected to the input device’s positive terminal, and the negative terminal is connected to the input device’s negative terminal. The input circuitry also has a common (+) and (-) terminal for providing power to the circuitry.
The output circuitry consists of 16 channels, each of which has one output terminal: the common terminal (C). The common terminal is connected to other devices in the control system, such as relays, solenoid valves, or other input modules. The output circuitry also has a positive (+) and negative (-) terminal for providing power to the circuitry.
Input Circuitry Wiring
The input circuitry wiring for the 1756-IB16 module is straightforward. Each of the 16 channels has two input terminals: the positive (+) and negative (-) terminals. The positive terminal is connected to the input signal’s positive terminal, and the negative terminal is connected to the input signal’s negative terminal.
The common (+) and (-) terminals are used to provide power to the input circuitry. The positive terminal is connected to the positive bus bar of the power supply, while the negative terminal is connected to the negative bus bar of the power supply.
Output Circuitry Wiring
The output circuitry wiring for the 1756-IB16 module is also straightforward. Each of the 16 channels has one output terminal: the common terminal (C). The common terminal is connected to other devices in the control system, such as relays, solenoid valves, or other input modules.
The positive (+) and negative (-) terminals are used to provide power to the output circuitry. The positive terminal is connected to the positive bus bar of the power supply, while the negative terminal is connected to the negative bus bar of the power supply.
