This configuration combines an isolated two-wire transmitter input with an RS-485 communication interface. It is intended for applications requiring a transmitter signal input and serial data exchange with compatible control or supervisory systems.\u003c\/p\u003e\n\u003ch3\u003eFunctional Configuration\u003c\/h3\u003e\n\u003cp\u003eThe model suffixes identify the following configuration:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYS170: YS100 series programmable controller.\u003c\/li\u003e\n\u003cli\u003e-012: Power supply version rated for 138-264 VAC or 120-340 VDC.\u003c\/li\u003e\n\u003cli\u003e\/A06: Isolated two-wire transmitter input.\u003c\/li\u003e\n\u003cli\u003e\/A31: RS-485 communication interface.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe \/A06 input option provides electrical isolation for the two-wire transmitter signal path. This is relevant when connecting field transmitters to a controller because the input configuration determines the signal interface and isolation arrangement.\u003c\/p\u003e\n\u003ch3\u003eCommunication Interface\u003c\/h3\u003e\n\u003cp\u003eThe \/A31 option provides RS-485 serial communication. The YS100 series documentation identifies this interface for communication with compatible equipment using supported communication protocols. The communication option must be considered when checking host-system compatibility and serial communication settings.\u003c\/p\u003e\n\u003ch3\u003eControl Functions and Signal Assignment\u003c\/h3\u003e\n\u003cp\u003eThe YS170 supports programmable control strategies. Its analog and discrete inputs and outputs can be assigned according to the user-defined control program. This allows signal routing and control functions to be configured for the intended process requirements.\u003c\/p\u003e\n\u003cp\u003eThe controller supports single-loop and dual-loop control configurations within the YS170 platform.
