Prolon VC2000 Series - Connecting Sensors & Peripherals

Prolon controllers come equipped with one or more inputs designed to monitor the many variables required by their
control sequences (temperature, humidity, pressure, dry contact, etc.). These inputs all share a single electrical
common connection. (Refer to I/O section for specic hardware / prole input conguration.)
Connecting Sensors & Peripherals
Active signals
Prolon controllers may read signals from active transmitters
such as humidity, pressure, CO2, gas levels, etc. Standard
signals accepted are either current (4-20mA) or voltage
(0-5Vdc/1-5Vdc/0-10Vdc*). The positive signal polarity
connects to the input terminal, the negative polarity to the
common strip.

sensors. These are non-polarity sensitive, with one wire
going to the input terminal, the other to the common strip.

or other digital logic. Contact must be non-polarity sensitive
and connect with one end going to the input terminal and
the other to the common strip.
