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.

★ For inputs from a thermocouple, use the specified wires or compensating leads.
★ For inputs from a resistance temperature detector, use lead wires with small resistance and no resistance

difference is present among the 3 wires (3-wire type).

★ Provide input signal lines away from power supply lines, power lines or load lines so as not to affect input

signal lines with noise induction.

★ Wire the power supply for instruments such that they do not receive noises from the power supply for

power devices.
The use of a noise filter is recommended in case that the equipment is vulnerable to noises.
Take note of the following points when using a noise filter.

◎ Install the noise filter as close to a temperature controller as possible.
Wire the instruments in as short a distance as possible to output lines (secondary side) of the noise

filter and power terminals for the temperature controller.
◎ Isolate the noise filter input line (primary side) from its output line (secondary side).
High-frequency elements of noises may be induced, resulting in no provision of much noise

attenuation effect as expected, in case of input and output wires being close one another, such as

being bundled together or installed in a same duct or tube.
◎ Wire the grounding wire of the noise filter in as short a distance as possible.
A long grounding wire is like inserting an inductance, resulting in deteriorated high-frequency

characteristics.

◎ Before installing the noise filter, peel off the paint applied on a mounting plate of the noise filter as
