ET224/ET228: Expansion Module for GV series with Potential Separation

The expansion module ET224 is used in combination with the device GT228/ET. The modules are connected via a BUS interface, which makes it simple to plug the devices together.

ET224: 4 pulse outputs, formats corresponds to those of the input signals, but with individual assignment of the output level for each output. Dimensions W x H x D = 34 x 118 x 140 mm (1,34 x 4,65 x 5,51").

ET228: 8 pulse outputs, formats corresponds to those of the input signals, but with individual assignment of the output level for each output. Dimensions W x H x D = 54 x 118 x 140 mm (2,13 x 4,65 x 5,51").
