Honeywell 2MLR-M02P-CC 2-Slot Main CPU Base for MasterLogic-200R, 24V DC Backplane

Product Overview

The Honeywell 2MLR-M02P-CC is a 2-slot main CPU base engineered for the MasterLogic-200R (ML200R) redundant PLC platform. This compact baseplate provides mechanical mounting, backplane communication, and 24 VDC power distribution for up to two I/O or communication modules. With 1500 VAC slot-to-slot isolation and a rugged industrial frame, it delivers reliable modularity for space-constrained automation deployments.

Features & Benefits

1. Compact 2-Slot Design: Ideal for small-footprint control cabinets where only a CPU and one expansion or communication module are required.
2. High Isolation Rating: 1500 VAC slot-to-slot isolation protects against ground loops and electrical transients.
3. Shared 8 A Backplane: Delivers ample current for high-density I/O or power-hungry communication modules.
4. Industrial Durability: Operates across -20°C to +60°C with 1 G vibration resistance for harsh factory floor conditions.
5. Redundancy Platform Ready: Designed specifically for ML200R redundant architectures, enabling hot-standby CPU configurations.

FAQ

Q: Is the 2MLR-M02P-CC compatible with standard MasterLogic-200 (non-redundant) CPUs?
A: The 2MLR-M02P-CC is optimized for MasterLogic-200R redundant systems. For standard MasterLogic-200 deployments, use the 2MLB-M04A or 2MLB-M06A main base series.

Q: What modules can be installed in the two slots?
A: Any MLR-series I/O, communication, or expansion driver modules designed for the MasterLogic-200R platform are supported.

Q: Can I expand beyond two slots using this base?
A: Yes. Install an expansion driver module (such as 2MLR-DBST for twisted pair or 2MLR-DBSF for fiber optic) in one slot to connect remote expansion bases.

Installation Guide

• Mount the base securely inside the control cabinet using panel-mount or DIN-rail brackets.
• Connect 24 VDC power to the base power terminals, observing correct polarity.
• Install the redundant CPU module (2MLR-CPUH/T or 2MLR-CPUH/F) into the designated CPU slot.
• Install up to two I/O or communication modules into the remaining slots, pressing firmly until the retention latches engage.
• Verify all module LED indicators show normal status before energizing the control strategy.

Selection Tips

• Slot Count: Choose the 2MLR-M02P-CC for minimal I/O count (2 slots). For larger local I/O requirements, consider the 2MLR-M06P-CC (6-slot) main base.
• Redundancy Planning: Pair with 2MLR-CPUH/T (twisted-pair network) or 2MLR-CPUH/F (fiber-optic network) redundant CPUs for high-availability architectures.
• Power Budget: Ensure your external 24 VDC supply can deliver the base consumption (211 mA) plus the total current draw of all installed modules.
• Cabinet Space: At 238 mm wide, verify horizontal rail or panel space in compact enclosures before ordering.
