K61-DL20 Switching Value Synchronous Remote Transmission   [DI input channels]：4 [DO output channels]：4 [Interface type]：Switch digital type [Size]：110*84.32*25.3mm [Product weight]：164±5g [Introduction]：This product is a cross-communication function product. Function: The sender collects 4-channel switch signal and transmits the data to the receiver through wireless (LoRa spread spectrum) or network port, and the receiver restores the 4-channel switch signal. Item Description Number of DI/DO channels 4 Interface Type Switch (digital) type Connection method 5.08mm industrial grade plug-in terminal Refresh rate When a signal change is detected, trigger immediately (debounce time 150ms) DI signal input 1. The dry and wet nodes are compatible, and the low-level input of the switching value is valid; 2. DI acquisition channel and GND: the effective voltage input range of low-level action is less than 0.7V; the withstand voltage range is less than 30V; reverse co
