The AXON can run on any DC voltage between 5 and 30 Vdc. The current consumption depends on the actual supply voltage, but is typically 110 mA at 12 Vdc for the 8A & 8D and up to 190 mA for the 5R (with all relays energized). A 2.1mm locking DC Power barrel connector with negative shell is used.
Connect the power supply to your power mains and then connect the 2.1mm locking barrel connector to the AXON.
Once power is applied to the AXON, the unit takes about 5 to 10 seconds to boot-up (except on first start-up or following a factory reset), see this article. The unit is ready once the “ACTIVITY” heartbeat light starts blinking.
Depending on the type of AXON that you are using, you will need to properly set the DIP switches found on the side of the unit.
AXON-8A Connections and Switch Settings
The AXON-8A’s flexible analog inputs can accept a wide range of signals. Sensors with various voltage outputs (±0.5, ±2.5, ±5, ±10, ±20 and -40 or +40 V) or current outputs (4-20mA), be they bipolar or differential, can all be connected to the AXON’s inputs. Single-ended measurements are also possible.
DIP switches are used to select whether the input (on an individual basis) operates in bipolar/differential mode (switch up) or in 4-20 mA mode (switch down).
The other set of switches is used to connect the (-) terminal of an individual input to ground if balanced/differential mode is not required (single-ended signals). If using 4-20 mA mode, ensure the corresponding (-) TO GND switch is up.
AXON-8D Connections and Switch Settings
The AXON-8D’s inputs are designed for reading logic levels or wet/dry relay contacts, with programmable active-high or active-low settings.
DIP switches are used to determine whether each input’s return signal is connected to the unit’s common ground, or not (ISOLATED). The other set of switches determines whether each individual input will have a pull-up resistor (10kΩ to internal +3.3V, diode protected against reverse or over-voltage) or not.
AXON-5R Connections
The AXON-5R’s relay outputs can control other devices. From remotely switching off a faulty device to automatically power-cycling network elements, the AXON-5R can take smart decisions to keep your operations humming along. The AXON 5R does not have any configuration switches.
