IQ DP-4000
SECTION 2 - HARDWARE DESCRIPTION
9. The discrete input can be configured to be either a
reset input or a sync pulse input. The input is
activated by a contact closure across terminal block
contacts 1 and 2. See Section 5. 1 5. 1 for configuring
this input.
1 0. Watt-hour Pulse. The Watt-hour pulse initiator is a
set of contacts that completes a circuit and sends a
pulse signal to an external pulse recorder. You can
program the amount of energy between pulses
using Setpoint Switches (see Section 5. 1 5.3). The
pulse initiator is a KYZ output, meaning the relay will
change state for each pulse.
2. 1.3 User-Supplied External Hardware
The IQ DP-4000 requires you to wire at least 2 , and up
to 3 current transformers into the CT terminal block
from an external location (see Figures 4.4 - 4. 1 5) .
These are user-supplied and must have a 5 amp
secondary. Potential transformers are required only for
voltages above 600 V and are wired directly to the AC
line connection terminals.
2. 1.4 Optional Communications Module
The IQ DP-4000 is an I M PACC-(Integrated Monitoring
Protection and Control Communications) compatible
device. IMPACC can remotely monitor, control and
program the IQ DP-4000 when it is equipped with the
optional communications module. An I PONI is typically
mounted on the back of the power module and connects
to the IQ DP-4000 via the communications port on the
lower right side of the rear of the chassis.
IMPACC is a noise immune communications system
that permits communications from the IQ DP-4000 to a
master computer via a high frequency carrier signal
over a shielded twisted pair of conductors. The
conductors can extend up to 1 0,000 feet without using
repeaters. The INCOM (Industrial Communications)
chip
allows
communications
between
IMPACC
compatible devices, and accounts for the system's high
degree of reliability.

2.1 .4.2 JMPACC Enhanced Graphics
Enhanced Graphics software provides the capability to
generate custom animated color graphics. For example,
animated one-line drawings of electrical power
distribution systems, flow diagrams of processes,
equipment elevation view, and other graphical
representations can be developed.
2. 1.4.3 IMPACC Connectivity
An I M PACC network or computer running Series I l l
software can interface with other networks. Examples of
I MPACC connectivity interfaces include:
•
PLCs (Programmable Logic Controllers)
•
DCSs (Distributed Control Systems)
•
BMSs (Building Management Systems)
•
PC-based graphical operator interface programs
