The KL1232 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit.
The KL1312 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal has two channels, whose signal state is displayed by light emitting diodes.
The KL1512 Bus Terminal is a 2-channel up or down counter and transports the counter value electrically isolated to the higher-level automation device.
The KL2012 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
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 KL2212 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL3012 analog input terminal handles signals in the range from 0 to 20 mA. The current is digitized to a resolution of 12 bits and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3112 analog input terminal handles signals in the range from 0 to 20 mA. The current is digitized to a resolution of 16 bits (the default is 15 bits), and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3122 analog input terminal handles signals in the range from 4 to 20 mA. The current is digitized to a resolution of 16 bits (the default is 15 bits), and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3312 analog input terminal allows thermocouples to be connected directly. The Bus Terminal’s circuitry can operate thermocouple sensors using the 2-wire technique.
