Motrona GT224 Signal Splitter for Incremental Encoders with Potential Separation

The GT224 is a fast and precise impulse distributor, which has one pulse input and four pulse outputs.

The signal distributors are available with two outputs (GT222), four outputs (GT224) and eight outputs (GT228) as standard.

The special feature of this signal distributor series is the modular design, through which the outputs can be expanded quickly and easily via bus connectors. Two expansion modules ET224 and ET228 with four or eight additional outputs are available for the GT228/ET variant.

With the GV version, this signal distributor series also offers a variant without electrical isolation.

Features

• 1 pulse input with format A, B, Z [HTL] or A, /A, B, /B, Z, /Z [RS422 / HTL differential]
• Input frequency up to 350 kHz [SE TTL / SE HTL] or 1 MHz [RS422 / HTL differential]
• 4 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 expansion of the number of outputs
  
• 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)
