Application and Installation
The 1440-SPD02-01RB is typically deployed in predictive maintenance architectures where rotational speed monitoring is mandatory for overspeed or underspeed protection. The module facilitates complex calculations including speed, zero-speed detection, and direction of rotation. It integrates seamlessly into the broader ControlLogix or PLC-based control systems via its DeviceNet interface. For proper operation, the module must be seated in a compatible 1440-TBx terminal base, which provides the necessary wiring terminations for field sensors and power distribution.
