Variable Input Sensor Control
Sensors/Contact Closures Trigger Relays According to Configuration
Time Delay, Rotations & Complex Events can be Configured
No Programming Necessary - Configuration Software Included
Operates Without a Computer
Intelligent Switching without a Computer is the foundation of the Reactor Series relay controllers. The Reactor Series will help
you activate a switch when it gets dark outside. If the door has been left open, it will close automatically. When the temperature
falls, another switch is triggered. If motion is detected, a light will turn on for a preset time. When soil in the ground is too dry,
a switch will be activated that can save your crops, save your energy, save you a trip to the field, and save you money.
Up to 8 timers and 4 rotations can be configured to control up to 8 relays based on 8 separate analog inputs. Programmable Trigger
Points can Trigger Timers and Rotation Counters when Analog inputs reach preconfigured levels.
Your Settings can be Saved
Users may load and save reactor settings into individual files. If you require individual settings for different events, seasons or applications
each configuration can be saved to your computer and uploaded when needed. Your configurations will always be backed up as well.
This saves you time loading configurations to the board.
Configure to Your Needs
The Reactor controller must be configured using a computer and the included software. All decisions are made based on your configuration settings. Configuration
settings are created and loaded into the Reactor controller using the NCD Configuration Utility. The Reactor is usually configured
using a USB communications module, but may be configured wirelessly. Configuration is a simple Point and Click process, setting
parameters to activate relays with user-defined limits.
Once configured, the Reactor CPU is constantly monitoring external sensors using 8 analog inputs. Inputs can be configured to
trigger relays, relay timers and relay activation sequences. Complex events can also be configured without any programming. Use the
Reactor as a Thermostat, a Motion Activated Light with a Programmable Timer, an Automatic Garage Door Closer, and much more.
The Configuration utility is available as a free download.
Who's Qualified to Use the Reactor Series?
Some computer skills required. The Reactor Relays do not require programming, simply configure the device with the included Configuration Utility. While
programming is not required and simple functions can be done rather easily with basic computer skills, complex events can be configured which will require
some understanding and patients.

Configure Each Input
The Reactor Relay allows users to define the activation of a relay or an event
based on the voltage readings of the analog inputs. An input can trigger a relay directly or an input can trigger an
event, such as a timer. If an input triggers a relay, the relay may turn on. If an input triggers a timer event, a timer may be started,
but a relay may or may not be turned on based on how you have configured the controller (the time delay may be before the relay triggers).
Triggering an event does not mean you are triggering a relay, it just means you are triggering an internal function. Relays may be associated
with this internal function to achieve a large number of possible operations.
Reactor controllers have up to 8 relays available depending on the actual model selected. Each relay can be assigned to a different
input or event. In the example shown below, Relay 1 is Controlled by Input 1 directly. Input 1 will turn Relay 1 ON. In
order for Relay 1 to activate, it must meet the conditions of the Input 1 configuration using the settings on the Input Configuration tab
There are many ways to directly control a relay from an input. Relays 1-5 in the below example shows how inputs can turn relays
on, off, toggle relay state, set the relay to match the state of the input, or set the relay to NOT equal the state of a input.
In the example below, Relay 6 is controlled by Timer 1. In other words, if Timer 1 is active, the relay will stay ON. Otherwise,
the relay will turn off. This is a great way to activate a light for a given period of time. If you are
interested in Time Delay Relay, timers will be discussed on our Time Delay Relay Page.
The configuration software makes it easy to configure each relay. Relays or
multiple relays can be can be assigned to each input.
Reactor 4-Output Screw Terminal with Normally Open, Normally Closed and Common are available for each relay. 20 and 30 amp boards will connect directly to the relays. The 30 amp is a SPST relay and only has Common and normally open. For more click here
Reactor Controllers have 1, 2, 4, or 8 Relays integrated into the circuit board. A relay is similar to a switch. The only
difference between a switch and a relay is the actual mechanism for changing the on/off status of the switch. On a
switch, you manually push on a piece of metal or plastic to operate the switch. On a relay, an electric current is
used to operate the switch. Relays do NOT provide a voltage output. They provide a contact closure output, exactly like
the terminals found on a light switch at your local hardware store. Wiring to a relay will be slightly different depending
on the model of Reactor controllers you choose.
Attention: 0 to 5 Volt Input Only
Please Note: Analog inputs can accept voltages from 0 to 5VDC ONLY. Higher voltages and negative voltages
will damage the Reactor controller. Users must NEVER apply a voltage to an
analog input on the Reactor controller when powered down.
