Toho TTM-i4N Digital Temperature Controller

The TTM-i4N Series is a high-reliability digital temperature controller that supports a wide range of sensor inputs (thermocouples, RTD) and control modes (PID, ON/OFF). Designed with an intuitive interface, it gives operators full visibility over process variables, alarms, and loop status.

Highlights:

• Universal input (K/J/R/T/N/S/B thermocouples, Pt100 / JPt100)

• Flexible control output (relay or SSR), optional second alarm output

• Full-featured PID control (with auto-tuning) or ON/OFF mode

• Event alarms (EV1 / EV2) for limit deviation, thresholds

• Non-volatile memory saves settings after power loss

• Meets industry safety and EMC standards

• Compact panel-mount design with easy installation
