Digital Controller Toho TTM-1020 Series is perfect for any application
that requires you to control two processes from one controller. A Dual
Channel Digital Controller, it can also be used as Temperature and Humidity
Controller, Cascade Controller, Remote Input Controller, or Positioning
Proportional Controller. It is compact and incredibly versatile— which
allows for a variety of functions. Options include RS-485 communications,
several event outputs, and a variety of analog retransmission outputs.
An optional 24V AC/DC power supply is also available.
The two-channel control setting allows
independent control of two-channels for both input and output; Temperature
and Humidity Control uses wet and dry bulb sensing by RTD input. With
Cascade Control, two inputs and one output are utilized, while Heating
and Cooling Control uses one input and two outputs. Positioning Proportional
Control provides input by feedback resistance, and Remote Control by
remote SV input. On the ¼ DIN controller, process value and setpoint
are displayed for both channels at the same time.
Dual Channel Digital Controller Toho
TTM-1020 Series accepts thermocouple, RTD, and DC current/voltage inputs.
Control output options include relay, SSR drive voltage, 1–5V, 0–10V,
and 4–20mA. Event outputs are configurable as high, low, absolute, or
deviation alarm outputs. The parameter mask function protects the parameters
from being changed by the operator. And six modes of key lock are possible.
With the option for RS-485 communications,
you can network up to 31 stations, with multi-drop two-line or three-line
system. These features combine to make the Toho TTM-1020 Dual Channel
Digital Controller the most advanced series of dual-channel digital
controllers available today.
