FAQ 

1.What is the type of the 1756-ESMCAP module?

The It is a capacitive energy storage module, which is an energy backup module配套 to the ControlLogix rack and is not an IO module.

2.Can the energy storage of the 1756-ESMCAP module ensure the continuous operation of the PLC for a long time?

Supported. The It is impossible to maintain the continuous operation of the PLC for a long time.

3.What are the overall dimensions and net weight of the 1756-ESMCAP complete machine?

The

• Overall dimensions of the machine: Height 129mm × Width 35mm × Depth 112mm
• Net weight of the machine: 0.24kg

4.What are the two core functions of the module when the 1756-ESMCAP loses power?

The

• Provide a short-term backup power supply to complete the writing of controller programs and critical data into non-volatile memory, preventing data loss in case of power failure.
• Maintain the built-in RTC real-time clock of the controller to continue timing.
• The super capacitor can only support short-term operation and cannot sustain the continuous operation of the PLC. Once the data saving action is completed, the controller will shut down.
