Honeywell 2MLR-E08P-CC 8-Slot Expansion I/O Base for MasterLogic-200R, 318 mm Rack

Product Overview

The Honeywell 2MLR-E08P-CC is an 8-slot expansion I/O base designed for the MasterLogic-200R redundant PLC series. It provides mechanical mounting, backplane communication, and DC power distribution for up to eight I/O or communication modules. With support for digital, analog, and communication modules, this base enables medium-scale automation systems to expand I/O capacity while maintaining deterministic data exchange across the backplane.

Features & Benefits

1. Medium-Capacity Expansion: Eight slots accommodate mixed I/O and communication modules for scalable system growth.
2. Redundant CPU Compatible: Works seamlessly with 2MLR-CPUH/T and 2MLR-CPUH/F redundant processors for high-availability architectures.
3. Deterministic Backplane: Integrated high-speed backplane bus ensures reliable communication and power distribution to all installed modules.
4. Flexible Network Topology: Supports both twisted-pair (CAT5) and fiber-optic expansion links through compatible driver modules.
5. Industrial Durability: Reinforced frame and isolated backplane design withstand harsh automation environments.

FAQ

Q: What is the maximum distance between the CPU base and this expansion base?
A: The total I/O cable length from the CPU base to the farthest expansion base is limited to 15 meters per system specification. For longer distances, use fiber-optic expansion drivers.

Q: Can I use this base with standard MasterLogic-200 (non-redundant) CPUs?
A: The 2MLR-E08P-CC is designed for MasterLogic-200R redundant systems. For non-redundant MasterLogic-200, use the 2MLB-E08A-CC expansion base.

Q: How many expansion bases can I connect to one CPU?
A: The MasterLogic-200R system supports up to 31 I/O bases total, including the main CPU base and all expansion bases.

Installation Guide

• Mount the base securely inside the control cabinet using panel-mount brackets.
• Connect the expansion base to the CPU base or upstream base using the appropriate 2MLC-E### extension cable (0.4 m to 15 m lengths available).
• Install up to eight I/O or communication modules into the available slots, pressing firmly until the retention latches engage.
• For network expansion, install an expansion driver module (2MLR-DBST for TP, 2MLR-DBSF for FO) in the designated slot.
• Verify all module LED indicators show normal status before commissioning the control strategy.

Selection Tips

• Slot Density: The 2MLR-E08P-CC provides 8 slots. If your application requires more I/O, consider the 2MLR-E12P-CC (12-slot) or 2MLR-E12H-CC (12-slot redundant) expansion base.
• Cable Length: For installations within 15 m of the CPU, twisted-pair cables are sufficient. For longer runs or electrically noisy environments, select fiber-optic drivers and cables.
• Redundancy Planning: Pair with redundant CPUs and redundant power supplies (2MLR-AC12/AC22/AC13/AC23) to achieve full system redundancy.
• Cabinet Space: At 318 mm wide, ensure adequate horizontal rail or panel space in your control cabinet.
