ControlWave Express Instruction Manual (CI-ControlWave Express)
3.3.3 Non-Isolated Analog Inputs (AI) on TB6 of Process I/O Board
Setting Jumpers See Section 3.2.1 for details on setting jumpers.
Wiring Each AI includes three terminals (field power, AI# and DGND). See
Software Configuration To use data from these AIs you must include a CWM_EIO board in
3-8
Process I/O Board terminal block connector TB6 provides interface to
three single-ended analog inputs (AIs).

Supply, see document PIP-ControlWave-LS.
Notes:
You must connect cable shields associated with AI wiring to the
ControlWave Express chassis ground.
Multiple shield terminations require you to supply a copper ground
bus. You must connect the ground bus to the ControlWave Express
chassis ground using up to a #4 AWG wire size. The ground bus
must accommodate a connection to a known good Earth ground (in
lieu of a direct connection from the ControlWave Express chassis
ground) and to all AI cable shields.
Use an appropriate terminal lug for shield wires and secure them to
the copper bus using industry rugged hardware (screw/bolt, lock
washer and nuts).
your ControlWave project using ControlWave Designer's I/O
Configurator, and then configure it. See the ControlWave Designer
Programmer's Handbook (D5125) for more information. That same
manual includes an I/O Mapping section that describes, for advanced
users, the I/O map for this board.
I/O Configuration and Wiring
Characteristics
Jumper-selectable using JP5, JP6, and
JP7 for either 4-20mA or 1-5V
operation.
Jumper JP4 determines whether AI
field power comes from system power
(bulk input supply applied to TB1-3
and TB1-4 on the CPU/System
Controller Board) or the external loop
power source connected to TB7-3 and
TB7-4 on the Process I/O board.
2 Hz low pass filter for each AI.
Surge Suppression.
Self calibrating.
