Toho TTM-002 Digital Temperature Controller

The Toho TTM-002 is a compact, low-cost, and versatile 1/32 DIN digital temperature controller designed for precise temperature regulation across industrial applications. With advanced PID self-tuning, multiple input compatibility, and robust safety features, it ensures stable operation even under demanding process conditions.

Key Features

Self-Tuning PID Control – Automatically adjusts PID constants for optimum performance and overshoot protection.

Multiple Inputs – Accepts thermocouples (K, J, T, R, N, S, B) and RTDs (Pt100, JPt100).

Compact Design – 24 × 48 mm with only 77 mm depth; ideal for space-limited panels.

User-Friendly Interface – Large dual display (PV: green, SV: red) with priority display for up to 9 screens.

Flexible Outputs – Relay contact (250 V AC, 3 A) or SSR drive voltage (12 V DC).

Advanced Functions – Manual control, blind function, digital PV filter, watchdog function, ON/OFF timer, and Auto/Manual switching.

Safety & Protection – IP66 / NEMA 4X rating, EEPROM error check, and watchdog monitoring.

Certifications – UL, cUL, CE approved for global compliance.
