Compatibility Hint
The GV220 and GT220 series are the successor models of the GV460 and GV480 family of pulse
splitters, which have proven themselves thousand times.
The new pulse splitters are able to largely replace the previous models functionally. However,
there are minor differences in the wiring, the DIL switch setting and the potential separating.
The main differences between the new products and their previous models are listed below.
Differences of the GV220 and GT220 series compared to their previous models:
GV22x / GT22x
GV46x / GV48x
Incremental input:
Signal level:
Max. frequencies:
Possible configurations:
RS422 (TTL), HTL Differencial, HTL PNP
(asymmetrical) und TTL PNP
(asymmetrical)
The set signal level and the set signal
format at the input always applies to all
channels (A, B and Z) and cannot be set
individually.
RS422 / TTL:
Differential voltage > 0,5 V
HTL Differential:
Differential voltage > 2 V
HTL (asymmetrical):
LOW 0 … 6 V, HIGH 8 … 40 V
TTL (asymmetrical):
LOW < 0,8 V, HIGH >2,0 V
max. 1 MHz at RS422 / TTL
max. 500 kHz at HTL Differential
max. 250kHz at SE TTL / SE HTL
Possible configurations:

PNP (asymmetrical)
The desired signal level and the
desired signal format can be set
separately for all channels (A, B
and Z) using the corresponding DIL
switches.
RS422 / TTL:
Differential voltage > 0,5 V
HTL (symmetrical):
10 … 30V
HTL (asymmetrical):
LOW 0 … 10 V, HIGH 15 … 30 V
max. 500 kHz at RS422 / TTL
max. 200 kHz at HTL Differential
max. 200kHz at HTL (asymmetrical)
