Ramp/Soak temperature controller REX-P REX-P General The REX-P is a high performance ramp/soak controller with accuracy of ±.% and. second sampling cycle time while retaining easyto-use operation. The REX-P has many standard functions to offer solutions for ramp/soak processing applications such as up to segments, two () alarms, four () or eight () time signal s, digital inputs for reset, run and hold mode change and universal input. REX-P also has standard features to make it suited for wide range of applications, such as three types of control mode, and four types of start. Control modes can be easily changed among ramp/soak control mode, fixed setpoint control mode and manual mode on REX-P. Four types of start are selectable. Digital communication, retransmission, and up to three () additional alarm/status s are available as option. Features Four sets of PID parameters Up to segments (maximum patterns) Universal input s, digital inputs, alarms Heat/cool control Position proportional control Ramp/soak, Fixed, Manual control mode start selection Three auxiliary alarm/status s Digital communications Four sets of PID parameters Up to four sets of PID parameters can be stored. The temperature range for each PID group is programmable. On Time and Off Time can be set for each time signal setting so that time signal can be used for auxiliary heater/cooler control and input signals to PLCs. Up to settings per pattern are available. Digital input (Heater ) (Heater ) (Cooler ) (Cooler ) P_E -digit display Level Level Level Level Time -digit display enables REX-P to display any temperature measured by thermocouple and RTD with the resolution of. C. Scaling and decimal point for current/voltage input are programmable. Control status can be changed among Reset, Run, Step, Hold by digital inputs. Pattern number also can be set by optional digital inputs. PLC Three control modes Pattern number REX-P has three control modes as standard.. Ramp/soak control mode. Fixed setpoint control mode.

ALM ALM Ramp/Soak temperature controller REX-P Features segments patterns Digital communications Maximum of segments per pattern can be memorized, and maximum patterns can be memorized. Each pattern can be linked together (Pattern link function) so that a program containing up to segments is possible. The REX-P offers an optional communications interface (RS-C, RS-A or RS-) for networking to computers, PLCs and SCADA software in your plant. Up to units can be interfaced on one RS-A, RS- communication line. patterns Repeat (n times) Pattern Pattern Pattern Pattern Host computer alarms, Up to additional alarm/status s Two alarms are standard feature of REX-P. Up to three Auxiliary s are possible as option. These s can be used for additional alarm/status s.

When ramp/soak control is started: start : Time of segment is not changed whatever the is. start : Time of segment will be shortened to keep the slope of segment. start : REX-P will search the first same value on the program as the, and control status will be Hold. start : REX-P will search the first same value on the program as the, and control status will be Run. start (Fixed time type) start (Time shortening/constant slope type) Analog Time Time Analog is available for recorder or data - logging equipment, etc. Either of the process value (), set value (SV), manipulation value (MV), deviation value (DEV) or segment value (TIME) can be as DC voltage or current.. C Driving control motor without feedback resistance The REX-P can drive a control motor without feedback resistance utilizing the new algorithm for position proportional control. It simplifies wiring and eliminates bothersome care for feedback resistance. Analog Sensor input Control Heat/cool control The heat/cool PID controller has heat and cool s for use where process-generated heat exists. The controller allows the input of overlap or dead band settings which can contribute to energy savings.
