CT 1.1 DC 12V Counter Controller Module | 0–999 Range PCB
CT 1.1 Counter Controller Module – Precision Counting & Relay Timing
Take full control of your automation and electronics projects with the CT 1.1 Counter Controller Module. Operating on DC 12V (or optional 24V), this compact PCB-based circuit board delivers a wide counting range of 0 to 999, adjustable relay timing, and robust construction — all in a lightweight, space-saving form factor. Whether you're building industrial automation setups, DIY electrical projects, or custom control systems, this module is a reliable workhorse.
Key Features
- Counting Range: 0–999; count value resets after power-off while pre-set parameters are saved
- Relay Trigger: When count reaches the set value, the relay can be triggered to open or close for a preset duration
- Adjustable Timing Range: 0.1 seconds to 999 minutes; relay can be set to close-then-open or open-then-close
- Conversion Contacts: Includes one set of normally open (NO) and normally closed (NC) contacts
- Pre-set Parameter Memory: Configured settings are retained after power-off
- High Durability: 10 million mechanical operations; over 100,000 electrical operations at 10A-250VAC
- Wide Operating Temperature: -40°C to 85°C — built for demanding environments

Frequently Asked Questions
Q: What is the counting range of the CT 1.1 Counter Controller Module?
A: The CT 1.1 Counter Controller Module supports a counting range of 0 to 999. The counting value will reset to zero after power-off, but all pre-configured parameters (such as set count value and timing settings) are saved even without power.
Q: Can the relay timing be customized on the CT 1.1 counter module?
A: Yes! The timing range is adjustable from 0.1 seconds to 999 minutes. You can configure the relay to close first then open, or open first then close — giving you full flexibility for your automation or control circuit needs.
Q: What voltage does the CT 1.1 Counter Controller Module operate on?
A: The module operates on DC 12V by default, with an optional DC 24V version available. It handles a contact load of 10A at 277V AC or 10A at 30V DC, making it suitable for a wide range of electrical control applications.
Q: Is the CT 1.1 module suitable for DIY electronics and industrial applications?
A: Absolutely. With its wide operating temperature range (-40°C to 85°C), high mechanical durability (10 million operations), and compact PCB form factor (50 × 40 × 20 mm), this counter controller module is well-suited for both DIY projects and more demanding industrial automation setups.
