The Modular-DSA I/O System provides specially designed modules that provide many
benefits in a distributed architecture. The Sensor Module (198-IB2S) is specifically designed
to interface standard photoelectric and proximity sensors from the area surrounding the
enclosure. Since the connection for standard sensors is available outside the enclosure via an
M12 connector, and power is sourced from DeviceNet, no additional wiring is necessary.
The Starter Modules (198-IA2XOW1, 198-IB2XOB1, and 198-IB2XOW1) are designed to
provide a fast, effective way to control and gather the basic information from either a DC
operated or an AC operated starter.
The connections to specific 190D/191D Compact Combination Starters are made via cable
harnesses, such as Cat. No. 198-MSACBL6. Additionally, the 198-IB2XOW1 module sources
input power from DeviceNet. This allows many applications to turn off control power and
still be able to read the inputs for diagnostics.
