4.1.3 Motor Control
The SDM-CD16AC is a UL approved Start/Stop motor controller. In the figure
below, a typical 5 Amp 115 VAC relay contact circuit shows how to control a
three phase motor starter in a Motor Control Center (MCC). Typically, the data
logger will automatically command the appropriate relay to energize the motor
starter. The relay in the SDM-CD16AC will remain latched until the data
logger program commands that the motor be turned off, at which time the relay
will open the circuit to the motor starter and the motor will stop.
The SDM-CD16AC can be used to control three phase pump motors, air
blowers, and large control valves in the same fashion.
