Overview
The Watlow PM3C1FJ-AAAABAA EZ-Zone PM is a scalable, panel-mount PID temperature controller designed for industrial heating and cooling applications. This controller reduces system complexity and thermal loop ownership cost, and can be ordered as a PID controller, an over/under limit controller, or with functions combined into an integrated controller. The unit is available in 1⁄32, 1⁄16, 1⁄8 and 1⁄4 DIN panel mount packages.
Key Features
- Successor to Watlow’s legacy SERIES 93, 935, and SD controllers with simplified menu operation; includes one universal input and optional dual outputs in 1/32, 1/16, 1/8 and 1/4 DIN sizes.
- Auto-tune PID capability for fast, efficient startup with simplified user-friendly interface and reduced training costs.
- Factory Mutual (FM) approved over and under-temperature limit capability with factory approvals including UL listed, CSA, CE, RoHS, and SEMI F47-0200.
- Multiple communications options support connectivity needs.
- Current monitoring detects heater current flow and provides alarm indication of failed output devices or heater loads.
