KL2124 | Bus Terminal, 4-channel digital output, 5 V DC, 20 mA
The KL2124 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation. The load current outputs of the KL2124 version are protected against overload and short circuit. The Bus Terminal contains four channels that indicate their signal state by means of light emitting diodes.
