Application

High-speed output module with 4 output channels of 8 bits each. Different output

signals can be chosen with the aid of jumpers. Suitable for processes in which a

large number of actuators have to be controlled, such as in the chemical industry andf actuators have to be controlled, such as in the chemical industry and

building automation.
