— ON / OFF open collector output × 4 or × 8
— Can be used optionally for cooling and signal control output.
— Each output is independent and sets up temperature, present value/
set point / target value, absolute value / deviation, output operation
(LOW / HIGH), and output operation (ON / OFF)
2. Setup of various operations: Various operations can be set up by combining items below.
— Object : TEMP → It allows you to set up if the object of operation is temperature.
— Object value : PV / SP / DV → It allows you to set up at what point it is ON and OFF.
PV : Present Value
SP : Set Point (Target value that changes synchronously as the PROGRAM
DV : Step's target value (within a step, a fixed value is maintained)
— Operating point : ABS / DEV → sets up absolute value(ABS) and deviation(DEV).
— Output operation : ON / OFF → ON/OFF is set up for operating point in absolute
