SY/MAX Class 8030 Type RIM-121 Schneider Electric Standard Analog Input Module

The Schneider Electric / Square D SY/MAX Class 8030 Type RIM-121 Standard Analog Input Module provides the capability of inputting four channels of high level analog input signals (4-20 mA, 1-5 VDC, 0-10 VDC, or ±10 VDC) to any SY/MAX Family Processor which possesses register I/O addressing capability. The analog module may be inserted into any slot of a register rack (except slot 1) or the register slot of a digital rack. Each module utilizes four register slot of a digital rack. Each module utilizes four registers in the system (one register per channel) in which the analog current of voltage being measured is converted to a value ranging from 0 to 9995, in increments of 5. This provides a register value in percent of full scale (2 decimal places). Live zero (open-circuit) detection on the 4-20 mA range is indicated by -1 appearing in the register. Simple programming techniques allow these input readings to be scaled to engineering values, provided the processor being used has math capability. The module requires no external power supply to operate (drawing its power from the SY/MAX Family power supply connected to the rack) and requires no additional components (such as current loop resistors). No user adjustment of span and zero is required, as automatic calibration is performed by the on-board microprocessor. A removable terminal strip facilitates quick replacement with no rewiring necessary.
