2MLF-DC8A Honeywell Analog Output Module 4-20mA | Oiltech Controls

2MLF-DC8A | Honeywell | MasterLogic-200 Current Output Module

The 2MLF-DC8A is a Honeywell MasterLogic-200 analog output module with 8 current output channels. Each channel outputs DC 4~20mA or DC 0~20mA. Load resistance is 550Ω or less. You set the output range per channel by program or parameter. The module drives valves, dampers, and variable speed drives in a MasterLogic-200 rack. It suits plants that need tight, per-channel current control on a compact card.

Oiltech Controls’s Insight

• Per-channel range setup lets one card mix 4~20mA and 0~20mA loops.
• Keep total loop load at or under 550Ω. Add isolators if wire runs are long.
• Eight outputs in one slot cut panel wiring on multi-valve skids.
• Set ranges in the project file, not by jumpers. This keeps spares simple.
• Check output scaling against the valve or drive stroke during commissioning.
• Keep spare channel configs documented for fast swap-out.

Where It Fits

• Honeywell MasterLogic-200 racks that need analog output expansion.
• Valve, damper, and positioner control loops.
• Variable speed drive reference signals.
• Skids with many current loops in a small panel.
• Retrofit jobs that keep existing MasterLogic-200 hardware online.

Supply and Warranty Terms

• 12-month warranty on this module.
• Dispatch in 24 to 28 hours.
• Shipping by FedEx, UPS, and DHL.
• Units are checked and tested before packing.

FAQ

Q: Can I run 4~20mA on some channels and 0~20mA on others in one 2MLF-DC8A?

A: Yes, you can. Range is set per channel by program or parameter. Map each channel in the project file before download. Label each field loop on the drawing. This stops a 0~20mA loop from under-driving a valve that expects 4~20mA.

Q: What load can one channel drive?

A: Keep load resistance at 550Ω or less per channel. Add up cable resistance and device input resistance. Long runs into high-impedance inputs can exceed the limit. In that case, use a signal isolator or a shorter route.

Q: How do I confirm the right spare before I order?

A: Check the rack is MasterLogic-200. Check the card label reads 2MLF-DC8A current output type. Do not swap it with a voltage output card. Send us your project file or rack photo. Our team confirms fit before we ship.

Q: What is a common field mistake with this card?

A: Mixed range setup. A channel set to 0~20mA drives more current at the low end than a 4~20mA loop expects. Valves can sit partly open at zero command. Confirm each channel range during loop check. Log the settings for future service.

Q: How fast do you ship, and what about warranty?

A: We dispatch in 24 to 28 hours. We ship by FedEx, UPS, or DHL. Every module carries a 12-month warranty. Each unit is tested before it leaves our warehouse.
