ET228: Expansion Module for GT series with Potential Separation, 8 Outputs

The expansion module ET228 is used in combination with the device GT228/ET. With the eight additional outputs that the ET228 offers,16 outputs can be achived. The modules are connected via a BUS interface, which makes it simple to plug the devices together.

Input frequency up to 350 kHz [SE TTL / SE HTL] or 1 MHz [RS422 / HTL differential]
8 pulse outputs, formats corresponds to those of the input signals, but with individual assignment of the output level for each output
BUS interface for quick and easy connection of the modules
Power supply 10 ... 30 VDC
Signal delay time max. 430 ns
Input level at RS422 / TTL (differential voltage > 0.5 V),
Input level at HTL differential (differential voltage > 2 V),
Input level at HTL asymmetric LOW: 0 ... 5 V HIGH: 9 ... 30 V
Input level at TTL (asymmetrical): LOW: 0 ... 0.6 V HIGH: 2.2 ... 5 V
Compact housing for mounting on 35 mm top hat rail (according to EN 60715)
Dimensions W x H x D = 54 x 118 x 140 mm (2,13 x 4,65 x 5,51")
