The module adopts the HIC communication optocoupler isolation scheme to drive the relay, which has stable performance and is very suitable for use in situations where there are fewer I0 ports and a large number of relays need to be driven.
The relay can load a MAX current of 10A (resistive load) and has three address control bits A2, A1, and A0. It can expand up to 8 sets of 1IC addresses. When you use 4 11C relay modules, you can connect 8 sets of modules on two buses through MOSTs. With only two 10 analog 1IC communication, you can control up to 4 x8=32 relays
If you choose a 16 channel I1C relay module, your MOST can control up to 128 relays through two 10 port analog 1IC, greatly saving you 10 ports in situations where multiple relays are used.
Control voltage: 0-220V, module type: 16 relay control
Working current: 100ma/piece, load current: 10A (resistive load)/7A (inductive load)
