CALogix Multi Loop Controller

CALogix Multi-Loop Controller - Obsolete

CALogix is a modular system that consists of a DIN-rail mounted base unit and up to 4 control modules. PID and logic modules can be added to the base unit in any configuration ensuring the exact requirements of your application can be met. CALogix is sub panel mounted which means that CALogix can be easily integrated within a system that has a central user interface. This could be an operator panel or a PC running an OPC based SCADA system or your own custom software.

This product is now obsolete. Call 1-800-876-0036 for assistance.
