2.4 ANALOG OUTPUT CONNECTIONS
The Halimeter
PLUS is equipped with 0-2.5 V and 4-20 mA output signals available at
the 10 pin rear panel terminal block as shown below. Each signal range corresponds to the
full scale range of the instrument from 0 - max range.
Connect to the terminal block by inserting wire conductor into the desired terminal and
tightening the terminal’s screw. The terminal block can be removed from the rear panel for
ease of wiring by gently pulling the block away from the panel. Re-connect the block by
gently pressing it back into the receptacle.
Use the VCC output (Pin 3) as the positive reference for the 4-20 mA output (AOUT1
– Pin
8) and the device ground (Pin 1 or 2) as the negative reference for the 2.5 V output (AOUT2
– Pin 7).
