1756-M14

The 1756-M14 expansion memory module by Allen Bradley is specifically designed to enhance the capabilities of ControlLogix systems. This memory unit utilizes Dynamic Random Access Memory (DRAM) technology to provide efficient and responsive memory capacity for demanding control applications.

In terms of reliability, the module can withstand shocks both during operation (30 g) and when not in use (50 g). Additionally, it features an operational vibration resistance of 2 g across a frequency spectrum of 10 to 500 Hz. Its construction ensures that it can handle a variety of challenging environments, boasting a relative humidity range from 5% to 95% without condensation.

For protection against electrical disturbances, the 1756-M14 includes surge immunity of up to 2 kV line-to-line and electrostatic discharge (ESD) resilience of 6 kV for contact situations. The isolation voltage is specified at 30 V continuous, ensuring safety in various applications.

In terms of power requirements, this module draws negligible backplane current, with readings showing 0.03 A at 5 VDC and none at 24 VDC. Its low power dissipation of 0.15 W minimizes the thermal impact on the overall system.

Designed to fit into a standard ControlLogix chassis slot, this module easily integrates into existing systems. The 1756-M14 serves as a dependable solution for expanding memory requirements in any robust automation framework.
