Using one of the software setpoint configurations (see General Setpoint Setup on page 36) in
conjunction with the setpoint option board gives the Model 370/375 the ability to directly control
external devices such as valves, relays, actuators, etc.
There are up to three setpoint outputs available. The activation and deactivation is controlled by
the setpoint configuration. The outputs are capable of driving up to one Amp at 20-280VAC & 2
