Avoid Backorders: Fast-Shipping Watlow Replacements for SOLO SLM Controllers

Struggling With Long Lead Times on Temperature Controllers?

If you’ve been sourcing Automation Direct SOLO SLM Single Loop Modular Temperature Controllers, you may have noticed the issue: lead times have stretched dramatically, with some customers currently backordered into November. These systems typically consist of one to seven single-loop modules with one input and two outputs, with optional ramp and soak profiling.

The good news? Watlow offers several alternatives that are available in days—not months.

Watlow Competitive Options

• EZ-ZONE® RM – Ships in 3–5 days.

  • Modular controller with 1–4 loops per module (up to 8 loops and 16 outputs when two modules are combined).

  • On-board Modbus® RTU available.

  • Flexible and scalable: configure from 1 to 152 control loops and up to 256 monitor points by mixing and matching modules.

  • Integrates on-off or PID control, monitoring, limit control, and communication modules.

• EPC2000 – A powerful back-of-panel option with fast availability.

• PM LEGACY & PM PLUS – Ideal for one or two loops of control, both shipping in as little as 3 days.
