Description: The Allen Bradley address retention I/O module is available with CompactLogix and MicroLogix processors. It has a current consumption of 60 mA at 5.1V and a maximum heat dissipation of 0.3 watts.

The Address Reserved I/O module is an input/output module of a programmable logic controller (PLC), which is used to connect input and output signals of external devices to the PLC.

The 1769-ARM address reserve I/O module usually includes an input interface, an output interface, an address reserve circuit, and a status indicator. The input interface is used to receive the input signal of the external device, the output interface is used to control the action of the external device, the address retention circuit is used to map the input signal and output signal to the address of the PLC, and the status indicator is used to display the status of the input signal and output signal.

The benefits of the 1769-ARM address reserved I/O module include:

1. The 1769-ARM realizes the isolation of the input signal and output signal from the PLC: the address retention I/O module can isolate the input signal and output signal of the external device from the PLC, avoiding the interference of the external device to the PLC and improving the reliability of the system.

2. 1769-ARM improves the security of the system: the address retention I/O module can ensure the correctness of the input signal and the output signal, avoid the occurrence of faults such as misoperation and short circuit, and improve the security of the system.

3. 1769-ARM improves the scalability of the system: The address retention I/O module can easily expand the number and type of PLC input/output interfaces, improving the scalability of the system.

Common address retention I/O modules include digital input module, digital output module, analog input module, analog output module, etc. They have different characteristics and application scenarios, and are suitable for different external device control requirements.
