05/02/2020 Introducing the second generation of the successful Neuron 500 and Axon 500 controllers
Axon 500 and Neuron 500 designations encompass the controllers featuring a universal combination of I/Os coupled with a set of multiple analog inputs and outputs and additional RS485/RS232 serial interfaces. Within the Neuron product line, these models are represented by the M503, L503 and L513 controllers.
| Model | Digital inputs | Digital outputs | Relay outputs | Analog inputs | Analog outputs | RS485 interface |
| M503 | 10 | 4 | 5 | 5 | 5 | 2 |
| L503 | 24 | 4 | 19 | 5 | 5 | 2 |
| L513 | 16 | 4 | 10 | 9 | 9 | 3 |
Additional analog I/Os open up a wide range of possible applications. Analog inputs are suitable for measuring voltage, current or resistance values from various analog sensors such as pressure meters, tensometers, resistance thermometers etc. Analog outputs are then designed for control and regulation of three-way valves, heat exchangers, pumps, electric motors and other multi-state devices. Thanks to these features the Neuron 500 became a notable success, followed by the Axon 500 line of M505, M515 and L505 controllers.
| Model | Digital inputs | Digital outputs | Relay outputs | Analog inputs | Analog outputs | RS485 interface | RS232 interface |
| M505 | 10 | 4 | 5 | 5 | 5 | 3 | 1 |
| M515 | 6 | - | 5 | 8 | 8 | 2 | 1 |
| L505 | 24 | 4 | 19 | 5 | 5 | 3 | 1 |
Enter the second generation
These well-liked products are now replaced by their second generation represented by the following models:
| Unipi Neuron M523 | Unipi Neuron L523 |
 |
 |
|
- 8 × digital input |
- 24 × digital input |
| Display on e-shop | Display on e-shop |
| Unipi Neuron L533 | Unipi Axon M525 |
 |
 |
|
- 12 × digital input |
- 8 × digital input |
| Display on e-shop | Display on e-shop |
All of these controllers retain all advantages of their predecessors, namely compact size, favourable price-per-I/O ratio, durable aluminium chassis and other pros. Default features of the respective product line were naturally retained as well - all new Neuron controllers retain 4× USB, a single 1-Wire bus and a 10/100Mbit Ethernet. The same thing applies for the Axon M525 as well, keeping its 1-Wire bus, 2× USB, 1Gbit Ethernet and an extended operating temperature range.

All of the mentioned new models are already in stock and available for orders. The replaced models were phased out of production and will no longer be available.
Coming soon
At the moment we are also developing the Unipi Axon L525 and Unipi Axon M535 controllers as a replacement for the Axon M515 and Axon L505. Both will be available very soon - make sure to follow our webpage for the latest news about our products, or subscribe to our newsletter.
