Selection help

Three questions to answer first

1
Control, limit, or both?

A controller holds your setpoint; a limit shuts the process down if it runs away. Many systems need both.

2
What DIN size fits the panel?

PM controllers come in 1/32, 1/16, 1/8 and 1/4 DIN cutouts. Match the existing hole when replacing.

3
How will you switch heater power?

Load current, voltage and phase point you to the right DIN-A-MITE series or ASPYRE model.
