The DS221 is a digital upgrade option for Rieter/SwissTex frequency-based rotary temperature transmitter systems. The device mounts in place of the original stator circuit board and accepts the Rieter frequency signal directly from the rotating transmitter. The DS221 is capable of one of two different outputs. When connected to + and - FREQUENCY, the DS221 generates the original Rieter frequency signal for use with a standard Rieter heater control system. When connected to + and - CURRENT, the DS221 generates a linear 4-20 mA current signal suitable for off-the-shelf process controllers.
