Product Description:

The Danaher designs CX312A6 Signal Electronic Reset Timer for accurate time-based control in industrial automation systems. The product has a tactile digital keypad which has a clear LCD display. Its base is made of a rotary socket to provide consideration in the panel mount. It can run on a wide range of operating voltages with a typical operating voltage of 120 to 240 VAC.

The output configuration of CX312A6 reset timer supports relay contacts rated up to 10A at 240 VAC for resistive loads. The timing range is flexible between milliseconds and hours. This makes it desirable to fit various conditions of application. It has a timing circuit that is microprocessor-based to allow high accuracy and repeatability. The encoder type integrated into this unit is a digital and membrane-switch matrix to offer precise manual input. It enables safe parameter entry and settings with the help of the up/down keys, depending on each digit. The environmental specifications of the CX312A6 reset timer are adapted to industrial conditions. It works reliably in a humidity range of 35-85 percent (non-condensing). It is capable of resisting vibration up to an amplitude of 0.75 mm at 10-55 Hz and shock up to 300 m/s2. The elevation tolerance extends to 2000m above sea level. The ambient operating temperature range of the timer is 0 °C to 50 °C. The storage conditions permit temperatures of -20 °C to 70 °C.

The cylindrical housing of the CX312A6 reset timer is made from high-durability thermoplastic with a metallic front faceplate for protection. The timer has a standard cutout size of 72mm x 72mm panel cutout, reducing the complexities of installation. The terminal connections are via rough screw terminals to provide safe wiring. It complies with NEMA and UL and fits in regulated industrial settings. It has ON-delay and OFF-delay support.
