FAQ
FAQ
Q1: What is the Allen-Bradley 1756-RM2K used for?
A: It is a redundancy module used in ControlLogix systems to synchronize primary and secondary controllers, helping maintain operation if the primary controller fails.
Q2: Does the 1756-RM2K support fiber-optic communication?
A: Yes. It uses fiber-optic communication for redundancy synchronization and data exchange between redundant controller chassis.
Q3: What is the difference between 1756-RM2 and 1756-RM2K?
A: Both provide the same basic redundancy functionality. The 1756-RM2K is the conformally coated version, offering additional protection against environmental contaminants.
Q4: How many 1756-RM2K modules are required for a redundant system?
A: Two modules are normally required, one installed in each redundant chassis.
Q5: Which fiber-optic cables are compatible with the 1756-RM2K?
A: Compatible cables include 1756-RMC1 (1 m), 1756-RMC3 (3 m), and 1756-RMC10 (10 m).
Q6: Which ControlLogix chassis are compatible with the 1756-RM2K?
A: It supports 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17 chassis.
Q7: What are the dimensions and weight of the 1756-RM2K?
A: Approximate dimensions are 140 × 36 × 145 mm (H × W × D), and the module weighs approximately 0.29 kg, excluding packaging.
Q8: Is the 1756-RM2K still available?
A: Rockwell Automation lists the 1756-RM2K as Active Mature, meaning it remains supported but is in a mature lifecycle stage.
