The Gino GXC series IP67 expansion module features one communication expansion branch and internal expansion using EtherCAT protocol (which can be used as an independent module). Each coupler can connect up to 32 slave modules, and the communication and power supply of the expansion module are independent, with stronger anti-interference ability. It can also provide independent power supply for sub module loads when the power supply is insufficient. The signal and signal expansion methods are more flexible and convenient. The wide temperature type (-30~70 ° C) design works stably, with an IP67 protection level, and can be applied to harsh environments. Rail mounted accessories can be optionally selected.
