2MLI-D22A Honeywell MasterLogic-200 16-Point DC 24V Digital Input Module
The 2MLI-D22A is a Honeywell MasterLogic-200 digital input module. It accepts 16 points of DC 24V input. Each channel supports current source or sink wiring. This gives engineers flexible field wiring for switches, sensors, and relay contacts. The module suits process control, factory automation, and legacy system support.
The design targets stable operation in control cabinets. It handles 0~55°C operating temperature and 5~95%RH humidity without condensation. The unit tolerates altitudes up to 2000 m. Keep it in clean air with no corrosive gas or dust. Contamination level stays below 2.

Temperature Range: The module runs from 0~55°C. Store it between -25~+70°C. Environmental Tolerance: It resists humidity up to 95%RH with no condensation. Noise Immunity: Use shielded field wiring and a clean 24V supply. This keeps signal readings stable in noisy cabinets. Resolution: Each point gives a clear ON/OFF state. Linearity and Frequency Response: These depend on the input filter and scan time of the MasterLogic-200 CPU.
Installation Guide
- Mount the module on the MasterLogic-200 backplane.
- Confirm DC 24V supply polarity before wiring.
- Choose source or sink mode for each input group.
- Use shielded cable for long field runs.
- Keep the cabinet free of corrosive gas and dust.
- Verify terminal torque and label each channel.
Commissioning and Maintenance
- Check channel LEDs during power-up.
- Test each point with a known 24V signal.
- Log the ON/OFF state in the CPU program.
- Inspect terminals and cable glands each service cycle.
- Clean the cabinet air path to avoid dust build-up.
These steps make debugging fast and downtime short. The front indicators help technicians find faults at a glance.
