Installation
General
The 415U Series modules are housed in a aluminum enclosure with
DIN rail mounting, providing options for up to 14 I/O points, and separate power and communications connectors. The enclosure measures 6.7” x 5.9” x 1.6” (170 mm x 150 mm x 40 mm), including the connectors. The antenna protrudes from the top.
Thermal
The 415U series modules contain a high-power radio that can generate a significant amount of heat.
For effective heat dissipation, the device must be mounted in the vertical orientation, with the antenna connection at the top, and with clearance of at least 25 mm on the right side to allow thermal convection.
When multiple circuits are active at the same time (Expansion I/O,
On-Board I/O, Battery Charging, Radio Transmit), and when powered from the “SUP” inputs, the 415U can overheat if it is also operating at the high end of the allowed temperature range.
If your radio transmitter will be operating in a high-duty cycle mode
(for example a repeater or base-station) you must check the de-rating charts below to ensure the radio will be able to operate continuously at your expected ambient temperature.
You can calculate the expected duty cycle of your device by calculating the expected number of messages and the expected message duration, or you can check the duty cycle once the system is p and running (Network Diagnostics >> Custom Survey >> All Tx
Frames).
If the device will be outside it’s thermal operating limit at the designed duty cycle, you can either reduce the transmit power, or you can power the device from a 13.8V supply through the BAT+ and GND terminals.

The worst case occurs when you are using all features of the 415U-
2-C at maximum.

All On-Board I/O circuits at maximum (analogs at 20mA, digital outputs at 200mA load)
115S modules connected to the “Expansion” port operating at maximum rated current (500mA).
•
•
Battery Charging at full rate (SLA battery recharging after extended power outage on BAT+ / GND terminals)
Use the de-rating chart above to limit the radio power and duty cycle depending on the expected maximum temperature.
N otee:
When operating from supply voltage 17V or below and at maximum ransmit power, you need to apply the additional derating shown.
415U-2-C and 415U-E-C Power level and modulation
The charts below show the radio power relative to the maximum radio power for the 415U-2-C and 415U-E-C models. The maximum radio power depends on the radio modulation mode selected.
Refer to Table 1 below to relate power level, modulation and the power levels on the charts shown on the following pages.
