Brainchild C21/C91 Established Process and Temperature controllers

Brainchild C21/C91 Established Process and Temperature controllers adalah pengontrol suhu elektronik pemasangan panel ukuran 1/32 DIN. Unit pengatur suhu ini ditenagai oleh suplai 11-26 atau 90-250 VDC/VAC, yang dilengkapi dengan 2 amp. mengontrol keluaran relai sebagai standar. Keluaran kedua dapat digunakan sebagai kontrol pendinginan, alarm, atau pengatur waktu diam. Tingkat pengambilan sampelnya yang cepat memungkinkan unit untuk mengontrol proses yang cepat. Model C21 diterapkan secara luas di industri berikut: cetakan injeksi plastik/karet, peralatan tungku vakum, program kontrol proses suhu semikonduktor, tungku sintering keramik, pewarnaan dan pengeringan serat, dll.

Fuzzy Logic plus pengontrol suhu berbasis mikroprosesor PID, menggabungkan satu tampilan LED 4 digit yang terang dan mudah dibaca, yang menunjukkan nilai proses dan nilai titik setel. Teknologi Fuzzy Logic memungkinkan suatu proses untuk mencapai set point yang telah ditentukan dalam waktu singkat, dengan minimum overshoot selama power-up atau gangguan beban eksternal.
