If the modules are not to be stacked, the connections are wired the same as described above in
Figure A-15. The Analog Output Module and the Digital Interface Module can be wired up to
50 meters from each other. Shielded wiring is recommended for distances greater than a few
meters or if the electronics are mounted in an area of high electromagnetic interference.
The voltage and current output connections are adjacent to the power and digital communication
connections. For a voltage output, connect to “+V out” and “-V out”, and for a current output
connect to “+I out” and “-I out”.
Mounting:
The backs of both the Digital Interface Module and Analog Output Module have attachments for
easy DIN rail mounting. To attach the modules to a DIN rail pull the orange tab at the bottom of
the module downward, slip the module onto the DIN rail and push the tab back in to secure the
module to the rail. A short piece of DIN rail is provided for mounting the Module to solid
surfaces.
Optional External Power:
The internal power source on the Analog Output Module will drive the current output through a
resistance of up to 500 ohms. The module can drive up to 1050 ohms if an external 24VDC
power source is used.
The Analog Output Module is supplied configured for internal power. To configure for external
power a jumper inside the module must be moved. The Analog Output Module and the Digital
Interface Module are similar in appearance, so make sure you are working with the Analog
Output Module before you proceed. To move the jumper, completely remove the two screws that
hold the Analog Output Module case together. With one hand, grasp the sides of the module just
below the case seam and squeeze firmly; the upper and lower covers will separate from each
other. Remove the top cover of the module and set it aside.
Hold the Analog Output module so the writing on the circuit board is upright. There is only one
jumper on the board, it is labeled JP1 and will be in the upper left-hand side of the board close to
the module connections. Three pins allow the jumper to be in one of two positions. To
configure for external power, locate the jumper connector onto the bottom two pins, to configure
for internal power locate the jumper connector onto the top two pins. See Figure A-16 below for
details.
