Connecting Communications or Analog Outputs (DLUX303)
With the purchase of DLUX303, the controllers are upgraded with additional features
such as RS485 communications, and analog outputs. A set of terminals are provided to
connect to RS485 communications and analog outputs.
Analog Outputs
DLUX303 provide analog outputs as either milliamps (0-20mA, 4-20mA) or voltage (0-
5V, 1-5V, 0-10V, 0-20V) signal output that represents each of the displayed temperature
(and humidity) values. These options can be used for connection to in-house data
acquisition, recorder, or alarm system.
Factory default settings are as follows:

Connect shielded wires to the appropriate signal terminals: I(+) for current (mA) or V(+)
for voltage (DC). For both current and voltage outputs, COM(-) is common terminal.
The controller itself must be programmed for the voltage or current signal and
corresponding scale (see Operations Section)
Communications
RS-485 communications are intended to communicate with a PC using ModBus RTU or
Standard Bus. The maximum number of chambers connected to a single PC is limited
