OUTPUT OPTIONS
The ACT-1B may be equipped with either a Current Output (IO) or an Analog
Output (AO), and/or a TTL Pulse Output (PO).
NOTE: Full scale RPM settings must have been specified when ordered;
these options are not field programmable.
The Current or Analog Outputs are connected to the terminals in the section
labeled ANALOG OUTPUT OPTION on the rear panel. The Pulse Output
is connected to the terminals under the section labeled OUT on the rear
panel.
CAUTION: The IO or AO COM is NOT isolated from the other
COM connections.
Current Output Option (IO)
The current output is 4 to 20 mA. This output is a current sink and
requires a source voltage. A 15 Vdc internal source is provided at the
terminal marked +VA. When using an external voltage source, the
current from that source is regulated by the ACT-1B.
Typical connections are as follows: (See Figure 4.)
When using the ACT-1B internal +15 Vdc source, connect the
Positive side of the load to the terminal marked +VA and the other
side of the load to the terminal marked OUT.
When using an external voltage source, connect the Negative side
of the external source to the terminal marked COM, the Positive
side of the supply to the Positive side of the load, and the other
side of the load to the terminal marked OUT.
