Industrial temperature controller A900

Product Features

Uses a three-color LCD display, with clear and bright colors, making the display more beautiful;

Uses low temperature drift coefficient components, with 0.2 class measurement accuracy;

The CPU uses Japan's Renesas latest industrial-grade chip, and Renesas chips are widely used in high-reliability places, such as automotive electronics;

Universal input, supports various thermocouples and thermal resistance inputs, and also supports linear signals, such as 4~20mA, 0~5V input;

Built-in Shimaden PID control algorithm, and equipped with unique anti-overshoot PID control, for precise temperature control;

Can be configured with 50 program segments, which can be flexibly divided into one or two groups of curves;

RS-485 communication interface, supports MODBUS RTU communication protocol, and instruments can also communicate in master-slave mode;

Up to two outputs can be configured to form heating and cooling control, and up to two alarm outputs can be configured.

Tips

(1) For input signals: thermocouples and Thermoresistance can be switched freely; linear signals are factory-set and cannot be changed to other types.  

(2) For master-slave control meters: the master meter is the programmable meter (PA) with TTL master-slave control selected for communication; the slave meter is the fixed-value meter (A), with TTL master-slave control also selected for communication. Example: master meter model – PA900-301003; slave meter model – A900-301003.  

(3) Example: a meter with size 96×96 delivers main output as SSR output, second-group output as relay output, 1 alarm output, no transmission, MODBUS communication, and K-type thermocouple input signal. So the selected model is A900-21100B-1-A.
