Digital Temperature Controller
FEATURES
- Self-Tuning PID (Heating / Cooling) The most appropriate PID constant is automatically computed for the controlled objects. PID constant is computed by performing the tuning, or when the hunting occ.
- Blind Function From the various existing parameters, only the required parameters can be indicated or set.
- Simplified Timer Function ON/OFF setting control is available after some certain interval. Function of ON/ OFF alarm output is independently usable.
- Priority Display Demanding parameter screens are monitored and set up under operational mode screen. (max. 9 points)
- Multiple Inputs Thermocouple / R.T.D. (Pt100 & JPt100) are selectable by front key.
- External Standard Conforms to "UL", "cUL" and "CE" markings (except TTM-002W) and compliant to "IP66"equivalent. The 6 substances restricted by the RoHS directives are not used.
- Size:
- 24mm x 48mm
- 48mm x 48mm
- 96mm x 48mm
- 48mm x 96mm
- 72mmx 72mm
- 96mm x 96mm
- Compact Size Compactly made with the depth of only 77mm (002W is 95mm).
- Manual Control (Balanceless & Bumpless) Manual output function is applicable for versatile applications of instrumentation systems.
- Sampling Cycle: 250mS
- Communication Function (RS-485: TOHO Protocol / MODBUS) The communication distance is extended up to 500 m, and max. of 31 units of controllers can be connected to a single computer at a time. Centralized supervision is available for collectiion of the whole data and alterration of setting values at remote location.
- Digital PV Filter A fi ltering is possible with a software for abrupt alteration of input value.
- PID with Overshoot Control Function A PID control is available to control the overshoot which occurs when the control is just starting. Further, in order to improve the controllability, PID algorithm of TTM-200 series had been introduced.
- DI Function The following functions are switchable:
- SV / SV2
- RUN / READY
- AUTO (RUN) / Manual
- Normal / Reverse Action
- AT (Auto-Tuning) Start
- Normal (SV2) / Reverse Action (SV)
- TIMER Start / Reset
- Others ① CT Input (w/ Input Monitor) ② Shift setting of OFF position during the ON / OFF control (for both Output 1 & 2). ③ Heating / Cooling Control (w/ PID Control Function on Cooling Side). ④ Ramp Function
