TOHO ELECTRONICS TTM200 - Manual (Page 8)

48-7009-E 1-2
1.1 Feature
★ Improved controllability due to new PID algorithm
(1) Time required to stabilize after start of control has been reduced (compared to Toho’s other models).
(2) Jumpless control function is supported, where post-disturbance overshoots are suppressed.
(3) Selection can be made from three types of PIDs.
(PID auto-tuning with the overshoot suppression function is set as factory default.)
★ Full multi-input
Thermocouples (13 types), resistance temperature detector (2 types), voltage (5 types) and current (one
type) are achieved as input specifications on a single unit. Their changes are possible through setting
changes of parameters. (“K thermocouple” is set as factory default)
★ Compact-sized with dimension of 55 mm (TTM-204) or 65 mm (other than TTM-204) in depth
★ Sampling cycle of 200 ms
★ Loader communication function
Best suited for setting various parameters
Dedicated cable: Option (with charge) (See page 7-9 for specifications.)
Dedicated software: Option (free-of-charge)
★ Blind function and priority screen for a simplified operation
Blind function: Among multiple parameters, only those needed can be displayed.
Priority screen: By transferring the necessary parameter screen to the operating mode screen, indication as
well as the setting would be possible without calling the parameter screens. (max. 20 screens)
★ The valve position proportional control is made possible without feedback resistance.
★ Bank function
Each process value (such as SV, PID constants) which varies in each process can be set at every bank,
enabling the setting changes according to the content of the process. (max. 8 points)
★ Simple timer function
Control of “start or stop of control after predetermined time has elapsed” can be done on a single unit.
The independent use of timer is also allowed. (Independent 3 points)
★ Protective structure In compliance with IP66 or equivalent (TTM-204 only)
★ Applicable to various instrumentation systems, using manual control
★ Password function
★ Modification to the settings at factory default is possible.
★ Display colors of PVs (measurement values) can be changed to green, red or orange.
★ Ramp function enables the setting of gradient.
★ Soft-start function
During PID control, a limit can be applied to an operation volume for a predetermined period of time
when the power switched.
★ Delay timer function
During ON/OFF control, the control output (primary/secondary) can be done with a predetermined lag
time.
★ Program run function
A max. of 8-step program operation is possible.
★ Bank auto-switchover run function
A bank auto-switchover run is possible by using 8 banks at most.
