Product Description:

The KL1002 input module serves as a bridge between field devices and a controller to read digital signals. It is made by Beckhoff and it produces superior and durable items with innovative features.

The KL1002 input module is designed for use within a modular I/O system. It provides two digital inputs by making it suitable for capturing simple on/off signals from sensors, switches or similar devices. It is built to operate with a nominal voltage of 24 V DC by allowing for a standard industrial power supply. Input signals are recognized as a logical “0” if they fall between -3 and +5 volts, and as a logical “1” if they range from 15 volts to 30 volts. Each input includes a typical filter time of 3.0 milliseconds which helps reduce the impact of electrical noise or signal bounce. It is connected using 4-wire technology and follows the EN 61131-2 with type 1 standard which aids in ensuring compatibility with industrial automation systems. The current drawn from the field inputs is typically around 5 mA while the internal K-bus which connects the module to the overall system consumes around 3 mA.

The KL1002 input module comes with electrical isolation rated at 500 V between the K-bus and the field potential by adding an extra layer of protection between the control and field sides. The module is lightweight and holds just 50 grams of weight for use in a range of temperatures from -25 to +60°C. It has an IP20 protection rating and supports variable installation positions. It has approvals and certifications by including CE, UL, ATEX and others which confirm its use in various regulated environments.
