The Hydran 201C i -1 (Figure 1-3 on page 1-5) is a full one-channel controller. When used
with the Hydran 201T i Intelligent Transmitter, the combination is called a

Type NEMA 4X instrument cabinet and contains a single electronic circuit board. The
digital/analog board handles communications chores and provides display, alarm and
analog output functions.
