Product Description:
The KL1232-0010 Input Terminal belongs to the KL Analog Input Modules series. It is built by Beckhoff and it is a durable, highly efficient and effective digital input terminal.
The KL1232-0010 input terminal can be installed on 35 mm DIN rail by conforming to EN 60715 with lock which ensures easy integration into control panels. Its housing is made of durable, non conductive and heat resistant plastic. It is designed to stretch short pulses for reliable signal detection. It has an input filter which filters noises. The module has a nominal voltage range of 20.4 V to 28.8 V DC. It comes in a compact terminal housing with signal LEDs which suggests a space saving form factor with visible status indication for diagnostics. It occupies two bits in the process image which matches its two digital inputs. It has a versatile wiring option with secure connection via spring loaded clamps. Because of the electrical isolation of 500 volts it ensures safety and noise immunity between logic and field circuits. The module tolerates high humidity environments without performance degradation if dry.
The KL1232-0010 input terminal draws minimal current of only 5 mA from the system bus. It is able to detect short pulses on signal edges and expands them for longer process recognition. The module uses a typical 4 wire setup suitable for digital signal interfacing. It enables stable mechanical and electrical connection between adjacent modules. In this module voltage range for a logic high input between 15…30 V to be registered as 1. It has a mass of 55 g which suggests it is a lightweight design for minimal load on mounting rails in industrial automation. The voltage range accepted as a logic low input is -3…+5 V.
Frequently Asked Questions about KL1232-0010:
Q: How does the 100 ms pulse expansion benefit short signal detection applications?
A: The 100 ms pulse extension ensures short pulses are reliably captured and registered. This is especially critical in fast-switching digital signal environments.
Q: What role does edge-triggered pulse expansion play in the KL1232-0010 module?
A: Edge-triggering ensures only state transitions trigger input detection. This reduces false positives caused by signal noise or fluctuation.
Q: Why is a 500 V electrical isolation important in KL1232-0010 digital terminals?
A: It protects internal circuits from voltage spikes and ground loops. This adds safety and signal integrity in industrial control systems.
Q: What advantage does a 0.2 ms input filter offer for KL1232-0010 applications?
A: It effectively suppresses transient signal noise and electrical interference. This improves input stability in high-noise environments.
Q: How does the KL1232-0010 ensure secure wiring connections in field use?
A: It uses spring-actuated terminals that maintain tight contact. This prevents loosening due to vibration or temperature changes.
