Remarks:
1, IB-K201F, K for medium-sized wall-mounted temperature control box, 2 for AC220V power supply/3 for AC380V power supply, F for function code (RS485 communication)
2、Function code can be combined according to the demand, the order is E, F, G, I, L, H, C, P, N, TH, if only L, H, C, P, N, TH function, need to add D in front of the code.
3, if there are other special technical or functional requirements, such as Ethernet communication, Profibus communication, multi-channel temperature measurement, fiber optic temperature measurement, etc., can contact us.
