The module is a digital output module that is equipped with 4 opto-triac outputs using phase-angle control. L and N are fed to the module for zero-crossing detection.
The module is equipped with 2 outputs for 3-wire connections. It is designed for X20 6-pin terminal blocks. If needed (e.g. for logistical reasons), the 12-pin terminal block can also be used.
This module is equipped with 8 digital channels that can be configured either as inputs or outputs. The inputs are designed for a sink circuit, and the outputs are designed for a source circuit.
The module is equipped with 6 outputs for 1 or 2-wire connections. The X20 6-pin terminal block can be used for universal 1-line wiring. 2-line wiring can be implemented using the 12-pin terminal block. The X20DO6321 is designed for sink output wiring.
