Terminal 36 is left unused for isolation reasons. Do not make any connections
to this terminal.
Opto-isolated (Open Collector) Outputs
The DYN module includes two opto-isolated outputs, 0 and 1.
The connections are functionally polarity sensitive and are designated H
(High) and L (Low). As the name suggests, these connections are isolated from
any others on the module. These opto-isolated outputs support reverse
connection protection within defined current load specifications.
The opto-isolated outputs are applied in either of two applications:
• Speed Signal Replication
• High/Low Signal Output
Speed Signal Replication
When either of the TTL speed input signals are to be replicated, and are input
to the TTL inputs (pins 17/18 or 21/22) of a module, apply the wiring as
shown in Figure 14
.
