KL2531 | Stepper motor terminal 24 V DC, 1.5 A

The KL2531 Bus Terminal is intended for the direct connection of different small stepper motors. The slimline PWM output stages for two motor coils are located in the Bus Terminal together with two inputs for limit switches. The KL2531 can be adjusted to the motor and the application by changing just a few parameters. 64-fold micro-stepping ensures particularly quiet and precise motor operation. In many applications, integrated zero-speed monitoring makes an encoder system or limit switch unnecessary.
