Johnson Controls C-7355-10 Digital Timer

The Johnson Controls C-7355-10 is a high-precision digital 7-day time clock engineered for commercial HVAC control and industrial automation. This 120 VAC electronic timer features dual-channel capability with two SPDT contacts, allowing for independent control of multiple circuits or equipment stages. With a capacity of up to 42 programmable events per day and a 1-minute shortest switching time, it provides the granular scheduling required for complex building automation systems and energy management protocols. The unit maintains an industrial-grade clock accuracy of ±4 minutes per year and includes a 7-day power backup to preserve your schedule during local outages. Designed for field reliability, the C-7355-10 is the professional standard for automating dampers, fans, and heating/cooling sequences where precise HVAC scheduling and load shedding are critical for operational efficiency.

• Dual-Channel SPDT Output: Enables the control of two separate electrical loads with independent 7-day programming logic.
• High Event Density: Supports 42 events per day, accommodating complex commercial occupancy schedules and HVAC automation needs.
• Terminal Protection: Built for rugged environments with reliable switching for motors, lighting, and specialized industrial timer applications.
• Internal Power Reserve: Features a robust 7-day backup to ensure the programmable timer does not lose settings during maintenance or power failure.

How do you override the schedule for emergency maintenance?
This model allows for manual override of the SPDT contacts, enabling technicians to bypass the digital schedule without losing the programmed 42 events.

Can this unit handle 240V applications?
The C-7355-10 is rated specifically for 120 VAC input. For higher voltage requirements, ensure you are utilizing a step-down transformer or selecting the correct voltage-rated Johnson Controls model for your control circuit.

What is the maximum wire gauge for the terminal blocks?
The terminals are designed to accept standard industrial control wiring, typically up to 14 AWG, ensuring secure connections for persistent logic signaling.
