KV-24AT is an AC power supply that is part of the Keyence KV PLC series. KV-24AT is a base unit. KV-24AT is 100 to 240 VAC power supply voltage input, and has a current consumption of 100mA or less. Ambient temperature conditions vary based on if the unit is in operation or in storage. In operation, the acceptable range is 32 to 122 Fahrenheit, and in storage, the acceptable range falls between -4 to 158 degrees Fahrenheit. Intermittent vibration occurs at amplitude .075 mm and acceleration 9.8 m/s. The KV-24AT weights approximately 330g, and it requires a very small amount of ambient particulates in the surrounding air. KV-24AT comes equipped with a 24-bit and 30 kHZ two-phase counter system which each have a two-point comparator function. Rated load on KV-24AT is 30 VDC, 0.1 A (500 to 502), 0.3 A (others), with a peak load current of 0.2 A (500 to 502) and 1 A. Output frequency is 50 kHz (500 to 502). Programming information for KV-24AT can be found in the programming instruction manual by Keyence. When using any products in the Visual KV series be sure to use the latest version of ladder support software. When using Ladder Builder for KV Ver. 1.0x make sure that you don't use the Change All function on the monitor. Correct Installation of KV-24AT, make sure that the unit is installed front facing or upward and that the distance between the panel or equipment is adequate to allow for proper heat dissipation.
