Figure 2. Power Modular Equipment Controller components
and key features.
Hardware
Controllers
Several styles of controllers provide flexibility and
expansion to meet application needs.
Power MEC Controller – 11xx
In addition to building and system management
functions, this controller provides control of the 32
points contained on the input/output point board.
Power MEC Controller– 12xx
In addition to control of the 32 points on the
input/output point board, this controller supports
analog and digital point expansion modules, which
can be mounted remote from the controller. This
capability expands the point capacity of the Power
MEC and provides for cost-effective placement of the
point terminations close to the load.
Power MEC Controller – 13xx
In addition to building and system management
functions and point expansion this controller supports
connection to Insight using a dial-up modem or an
APOGEE Ethernet Microserver. This allows use of the
Power MEC in applications that are remote from the
central console.
Power MEC Controller – 1xxxEx
The Power MEC “E” versions support industry
standard TCP/IP networks through a direct
connection to 10/100 BaseT for ALN communications.
Power MEC Controller – 12xxF, 13xxF
The Power MEC “F” version adds three connections
to the Floor Level Network (FLN), for a total of 96
devices.
Power MEC Controller – 12xxL, 13xxL
The Power MEC “L” version adds LonWorks
compatibility. It is equipped with a Neuron
Microprocessor and FTT-10A Transceiver. Instead of
three connections to the APOGEE P1 Floor Level
Network, it has a single connection for a LonWorks
network.
The “L” versions have a LonWorks network database
server embedded. This database maintains a
dynamic, real-time representation of the LonWorks
network including connections/bindings, node status,
and configuration parameters values.
The Power MEC consists of the following three major
components:
•
Input/Output Point Board
The input/output point board contains 32 points that
perform A/D or D/A conversion, signal processing,
point command output and communication with the
controller board. The terminal blocks are removable
for easy termination of field wiring. The analog input
points are selectable to be 0-10V, 4-20mA, 1K RTD or
optional 100K Thermistor. The analog output points
are also selectable to be either 0-10V or 4-20mA. The
digital inputs are dry contact, with four being pulse
accumulator inputs. The digital outputs support
110/220V Form C rated relays.
•
Power Supply
The power supply provides regulated power to the
input/output point board and active sensors. The
power supply is internal to the Power MEC housing,
simplifying installation and troubleshooting.
The power supply works with the controller board to
ensure smooth power up and down sequences for the
equipment controlled by the I/O point board and
analog and digital point blocks, even through brown-
out conditions.
