The TP-Series dual display 4-digit PID Process/Temperature Controllers with Auto-tuning are available in 48 x 48 mm dual display with 1 alarm, 96 x 48 mm dual display with 1 alarm and 96 x 96mm dual display with 1 alarm. They have relay output, signal voltage for SSR, analogue current 4-20mA, analogue voltage 0-10V, multi-sensor input, 100-240VAC supply, 24VAC/DC supply, with second alarm, heater burnout alarm 5A rated, heater burnout alarm 10A rated, cooling output relay, cooling output signal voltage, cooling output current 4-20mA, cooling output SSR, RS485 serial communications, SP1/SP2 external selection, loop break alarm, ASR, V, 240AC, 24VAC, A2, W(5A), W(10A), DR, DS, DA, DT, C5, SM, LA.
This handbook describes the features, specifications, and optional functions of the IMO TP-Series digital PID temperature and process controllers. It covers three models – TP40A, TP80A, and TP90A – and details display options, input types, alarm functions, and communication interfaces.
The document includes wiring connection diagrams, mounting dimensions, power requirements, and configuration procedures for RS‑485/Modbus communication, heater burnout detection, and various output types. Optional features such as a second alarm, heat/cool compensation, and serial communication are also explained.
