Temperature Controller (Process Controllers)
Compact size program controller with high functionality and high performance
Features
Program Controller Specifications
A liquid crystal display program controller with maximum of 15 patterns and 99 steps.
Full Multiple Inputs
The multiple inputs of Thermocouple (13 types)
- RTD (2 types)
- Voltage (5 types)
- Current (1 type) input
Utilizes a liquid crystal display
- The indication range has been extended to 5 digits
- Realized the various indication with 7 segments
- Adopted LED for the back light
Backup and Initialization for the Setting Value.
Compact Size
A compact sized body with depth of only 65mm. In addition, the protrusion of the front panel is only 2mm when TTM-339 is mounted.
Loader communication function
It is best for the set up work of a complicated parameter peculiar to the program controller.
- Cable: Option (sold separately)
- Software: Option (free) It can be downloaded from our website (Under development)
Blind function
The system can be configured so that only the selected parameters are displayed from the set of parameters.
Manual control
A manual output function enables application of various instrumentation systems.
Communication function (RS485: TOHO exclusive protocol / MODBUS)
The cable can be extended up to the length of 500m, and can connect up to 31 units simultaneously. With one host computer, a centralized control such as "The collection of all data" and "Change of respective setting value" are possible from a distance place Standard Specifications Function
