Monarch Instrument ACT-1B Series - Manual (Page 8)

5
Current Output Option (IO)
The current output is 4 to 20 mA. This output is a current source and
has a 12 Vdc internal compliance voltage. (Optional 24 Vdc may be
ordered).
Typical connections are as follows: (See Figure 4.)
Connect the Positive side of the load to the terminal marked OUT
and the other (Negative) side of the load to the terminal marked
COM.
Do not use an external voltage supply.
Figure 4 Current Output Option Connections
NOTE: With the internal 12 Vdc compliance voltage the maximum
load for the current loop is 500 Ohms.
If the optional 24 Vdc compliance option is ordered the
maximum load will be 1000 Ohms.
6
Analog Output Option (AO)
The analog output is 0 to 5 Vdc.
Connect the Positive side of the signal to the terminal marked OUT,
and the Return side of the signal to the terminal marked COM.
NOTE: If your ACT-1B is equipped with either a current output or
an analog output, the full-scale output has been factory preset
to the speed range specified at the time of purchase. The
output range may be programmed using the optional USB
Programming Cable and PM Remote Software.
Pulse Repeater Output Option (PO)
The Pulse Repeater output provides a conditioned TTL positive going
5 V pulse out for each pulse in.
Connect the Positive signal wire (+5 V pulse) to terminal marked +P
and the Return to the terminal marked COM in the rear panel section
labeled OUT.
NOTE: The polarity of the optional pulse output can be set by the
user using the optional USB Programming Cable and PM
Remote Software.
