What you're looking at
The E5CC-TQQ3A5M-000: Outputs are three relay contacts and two voltage-pulse (SSR drive) outputs, so you can drive a contactor or a solid-state relay without an extra interface card. The dual-color LCD shows 4 digits per row (0.600" and 0.280" character heights), and the backlight makes it readable in dim cabinets. Control is either on/off or PID, which covers most process loops in packaging lines, ovens, and environmental chambers. The IP66 front panel means it can handle washdowns — a good fit for food and beverage or chemical dosing skids.
