General Specification
The 4/8-channel analog output terminals generate signals in the range between 0 to 20 mA. The power is supplied
to the process level with a resolution of 12 bits and is electrically isolated. The output stage is powered by the 24 V supply. In the 4-channel Bus Terminal, the four outputs are 2-wire versions. The 8-channel variants combine all eight channels in one housing and are
particularly suitable for space-saving installation in control cabinets. The use of single conductor connection technology enables the connection
of multi-channel actuator
A mechanical device for moving or controlling a mechanism or system. An actuator typically is a mechanical device which transforms an input signal (usually an electrical signal) into motion technology with minimum space requirements.
The Bus Terminals have a common ground potential. The power contacts are connected through. The reference ground of the outputs is the
0 V power contact. The LEDs indicate the data exchange with the Bus Coupler.
