芬兰采购需求：控制系统设备、数字输入、继电器输出

I'm interested in sourcing a specific type of controller that operates with a 0-10V input and is compatible with Triac technology. I would like to know where I can purchase sample units for evaluation. Additionally, it would be great if you could provide details on pricing, availability, and any minimum order quantities or lead times for these samples. Looking forward to your prompt response so I can move forward with testing. Thank you!
