Frequently Asked Questions
What exactly is included in the .8300 Lite version
The .8300 is the Lite model of the OPTA 8A range. It provides 8 configurable inputs, 4 relay outputs, Ethernet and USB-C, focusing on core features without the extra wireless or serial options found on higher variants.
Can I read analogue sensors directly
Yes. Each of the 8 inputs can be configured for 0–10 V analogue or used as standard digital inputs, allowing direct connection of many transducers.
How are the relay outputs rated
There are 4 normally open relay outputs rated 10 A AC1 at 250 V AC. Always check load type and inrush to ensure suitability, or interpose a contactor where required.
Which tools can I use to program it
You can program via Arduino IDE or an IEC 61131-3 environment, giving both maker-friendly and industrial options. Use USB-C for programming and diagnostics.
Does it support networking out of the box
Yes. The integrated Ethernet port can be used for programming over network, diagnostics and integration such as Modbus TCP on supported firmware.
