Communication Expansion Module YM-485 provides RS-485 port,ModBus-RTU protocol; 32(128) meters are connected as a network. Data Acquisition (Expansion) Each YM-K2 module collects 2 routs of dry contacts and accumulates the counting. Control (Expansion) Each YM-K2 provides 2 relay outputs, which can be controlled by communication, remote control or by some measured parameter. Analog Output (Expansion) Each YM-A20 provides 2 DC4-20mA outputs, corresponding to some parameter.
