PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1203-SM1 is a communication interface module designed for the SLC 500 system. It connects SCANport peripheral devices directly to an SLC backplane. The module draws 300 mA at 5V DC from the SLC backplane. It also supplies 60 mA at 12V DC to the SCANport load. This interface facilitates data exchange between drives and programmable controllers.
Operating temperatures for the unit range between 0 and 60 degrees Celsius. Storage temperatures withstand conditions from -40 to 85 degrees Celsius. The module operates in non-condensing relative humidity between 5 and 95 percent. It supports 16-bit logic commands, status words, and references in both Basic and Enhanced modes. Mechanical construction conforms to Category I shock and vibration ratings.
