Sensor Attachment
Connect the desired sensors (sold separately) to the available ports on the ENVIROMUX. Sensors come with one of two
connection methods, RJ45 and individual wires for terminal connection. This section explains both methods of connection.
Configuration of these sensors will come later in this
manual.
RJ45 Sensor Ports
1. Connect each external sensor having an RJ45 male
connector on it (ENVIROMUX-STS, ENVIROMUX-
SHS, ENVIROMUX-STHS, ENVIROMUX-LDS) to one
of the female connectors labeled "RJ45 Sensors" on
the ENVIROMUX. Male connectors should snap into
place. Cables may be up to 1000 feet in length. See
page 121 for wiring specification and pinout.
Note: It is very important to locate the temperature
and/or humidity sensors away from ventilation sources
and fans.
Figure 4- Sensors connected by cables with RJ45 connectors
The RJ45 SENSORS ports can be used to connect a variety of sensors. Specifically on the ENVIROMUX-16D, the combined
power load of all 12VDC sensors on each row of ports (ports 1-8 is one row and ports 9-16 is the second) cannot exceed 500mA
per row. Some sensors use more power than others. The table below provides the top power users:
Sensor
12VDC Power
Consumption
in mA
Sensor
12VDC Power
Consumption
in mA
ENVIROMUX-S420MA 120 ENVIROMUX-ACLM-V 70
ENVIROMUX-S420MA-24V 130 ENVIROMUX-S5VDC(-5V) 100
ENVIROMUX-ACLM-P 100
Caution: Be careful not to overload the ENVIROMUX-16D as failure may occur and damage to the ENVIROMUX may
result.
2. Some sensors do not have RJ45 connectors on them
and instead have terminal blocks. These can either be
connected to the "DIGITAL IN" connectors or they can
be terminated and plugged into the remaining RJ45
connectors (see figure-right ). (The illustration uses
CAT5 patch cable to make cable connection easy.)
Some examples of these sensors include ENVIROMUX-
IMD, ENVIROMUX-IMD-CM, ENVIROMUX-VSS,
ENVIROMUX-SDS, and ENVIROMUX-GBS. Cables
may be up to 1000 feet in length.
Note: For sensors requiring 5VDC power source,
connect the wht/brown wire to pin 4 instead of pin 7.
