The EL3124 analog input terminal handles signals in the range from 4 to 20 mA. The current is digitized to a resolution of 16 bits and is transmitted, in an electrically isolated form, to the higher-level automation device.
the EL4124 analog output terminal generates signals in the range between 4 and 20 mA. The power is supplied to the process level with a resolution of 16 bits and is electrically isolated.
The KL1124 digital input terminal acquires the binary 5 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 contains four channels that indicate its signal state by means of light emitting diodes. The 5 V supply voltage can be generated with the power supply terminal and fed into the power contacts.
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.
