Product Description:

The timer CT531A6 is designed by Danaher with a 4-digit red lens LED display and a plug-in configuration. It operates at 120 V AC with ±10% tolerance and shows compatibility with both 50/60 Hz frequencies. This unit uses a 15-pin Cycl-Flex base for connection and its rear screw terminals are numbered for easy wiring and setup.

The CT531A6 timer features DPDT timed and instantaneous relay contact outputs. Its contact rating is 10 A at 120 V AC for resistive loads and supports up to 1/6 HP motor load at 120 V AC, while its load capacity also includes 1/2 HP at 240 V AC for inductive circuits. The timer’s display is used for countdown or fixed-time readouts and its timing progress is shown clearly on the front-panel display. A pilot LED indicates when the unit is actively timing and its thumbwheel switches allow precise digital setpoint adjustments. The CT531A6 timer retains settings mechanically without the need for power and no software or external programming is needed to configure this device. Its timing accuracy is ±10% for full-scale selected range and its repetitive accuracy is within ±0.1% under consistent operating conditions. The timing range can be selected from 0 to 60 hours and its DIP switches allow users to change timing range as well as output mode.

The CT531A6 timer offers on-delay and interval (off-delay) timing modes. Its timed relays activate after the preset delay in standard mode and in interval mode, the output remains on during timing and turns off after. This unit resists vibrations up to 2.5 g at 10–100 Hz and its housing is made from flame-rated thermoplastic for industrial use. It mounts through a 3.19-inch panel cutout with accessories and its depth behind the panel is 4.4 inches, while it carries a weight of nearly 2.0 pounds.

Frequently Asked Questions about CT531A6:

Q: How does the 15-pin Cycl-Flex base of the CT531A6 timer help with installation?

A: The 15-pin Cycl-Flex base provides a stable connection for reliable performance and makes installation easier by offering clearly numbered rear screw terminals for simplified wiring.

Q: Why does the CT531A6 timer feature mechanical retention for settings?

A: The mechanical retention ensures that the timer's settings are maintained even without power, eliminating the risk of losing configurations after power outages or during system resets.

Q: How does the ±0.1% repetitive accuracy of the CT531A6 timer benefit users?

A: This level of accuracy ensures reliable, consistent performance across multiple cycles, enhancing overall system reliability and preventing errors in time-sensitive industrial processes.

Q: Why does the CT531A6 timer offer both on-delay and interval timing modes?

A: These modes provide flexibility for various applications, enabling users to choose whether the output activates after the preset delay (on-delay) or remains on until the timing completes (interval mode).

Q: How does the 2.5g vibration resistance of the CT531A6 timer enhance its durability?

A: This feature ensures that the timer operates smoothly even in environments where vibrations or mechanical stress are present, making it ideal for industrial machines and rugged settings.
