AT Auto Tuning
CT Current Transformer
DI Digital Input
DO Digital Output
(Control outputs of relay and voltage pulse, and event output)
EV Event
LSP Local Set Point. The meaning of LSP and SP is same in case of the SDC15.
MFB Motor Feed Back. This indicates the feed back of motor opening which is used for position proportional
control. (This controller does not have MFB function.)
MV Manipulated Variable
PV Process Variable
RSP Remote Set Point. This is the set point which is set by the analog input from an external device. (This
controller does not have RSP function.)
SP Set Point
ST Self-Tuning
U Unit. This indicates the minimum digit of the selected PV input range with industrial unit (°C, Pa, l/min.,
etc.). 1U = 1°C in a range of –200 to +200°C. 1U = 0.1°C in a range of 0.0 to 200.0°C. Additionally, 1U =
0.01 when the DC voltage input is scaled to 0.00 to 10.00. Furthermore, 0.1U means 1/10 of 1U.
