FAQ

Q: What is the difference between the 2MLR-E12P and the 2MLR-E12H?
A: The 2MLR-E12P is a standard 12-slot expansion base for non-redundant or redundant MasterLogic-200R systems. The 2MLR-E12H is a dedicated redundant expansion base with dual-backplane architecture for enhanced fault tolerance.

Q: Can I use this base with non-redundant MasterLogic-200 CPUs?
A: Yes, the 2MLR-E12P is compatible with both standard MasterLogic-200 and redundant MasterLogic-200R CPU modules.

Q: What is the maximum distance between the CPU base and this expansion base?
A: In redundant systems using 2MLR-CPUH/# CPUs, local I/O bases communicate with the CPU via Industrial Ethernet using UTP CAT5 cable up to a maximum distance of 100 meters.

Installation Guide

• Mount the base securely using panel-mount or DIN-rail brackets inside the control cabinet.
• Connect 24 VDC power to the base power terminals, ensuring proper polarity.
• Install up to 12 I/O modules into the available slots, pressing firmly until the retention latches engage.
• For redundant systems, install the 2MLR-CPUH/T or 2MLR-CPUH/F CPU module in the designated CPU slot of the main base.
• Connect expansion bases to the CPU base using the appropriate 2MLR-DBST (TP) or 2MLR-DBSF (FO) expansion driver and compatible extension cables.
• Verify all module LEDs indicate normal operation before commissioning the control strategy.

Selection Tips

• I/O Count Planning: The 2MLR-E12P provides 12 slots. Calculate your total required digital, analog, and communication modules to ensure adequate expansion capacity.
• Redundancy Requirements: If your application demands high availability, pair the 2MLR-E12P with redundant CPUs (2MLR-CPUH/T or 2MLR-CPUH/F) and redundant power supplies (2MLR-AC12/AC22/AC13/AC23).
• Cabinet Space: With dimensions of 481 × 98 × 19 mm, verify horizontal rail or panel space in your control cabinet before ordering.
• Expansion Distance: For installations where the expansion base is located remotely from the CPU, select the appropriate expansion driver (TP for copper, FO for fiber optic) based on distance and environmental interference.
