SSI interface modulesPCD2.H150 SSI interface moduleI/O modules and I/O terminal blocks may only be plugged in and removed when the Saia PCD® and the external +24 V are disconnected from the power supply.5-116PCD2.H1505.17.1PCD2.H150, SSI interface module for absolute encoderApplicationThe PCD2.H150 Module is an interface module for the SSI standard. (SSI = Synchronous Serial Interface). The SSI standard is used with most absolute encoders. Details of SSI specifications can be obtained from the STEGMANN company’s brochure: “SSI-Technical Information”.The hardware consists of an RS-422 port for the SSI interface and 4 general- purpose digital outputs. Functionality is provided by an FPGA (field programmable gate array).Technical dataResolution: Clock frequency:Frequency has to be selected depending on cable length:Data code: Read mode:Offset position:Execution time: Cable break detection: Flags
