POWER AND OUTPUT CONNECTIONS
Power
For best results, the Power should be relatively “clean” and within the specified
variation limits. Drawing power from heavily loaded circuits or from circuits
that also power loads that cycle on and off, should be avoided.
Current Output
DIP switch S2 should be set for the desired full scale output current. (20 mA =
ON; 1 mA = OFF).
Voltage Output

of the mode/calibration DIP switches (S1-1 or S1-2). Therefore, the scaling can be aborted any time
before the full scale value is saved. This is accomplished by cycling power to the IAMA. The IAMA
will restore the factory or previous field scaling values at power up depending on the setting of the
DIP switches. See Mode Selection for more detailed instructions for selecting factory and field
modes at power up. See Table 2 and 3 for the input and output range DIP switch settings.
