Temperature transmitter, input thermocouple or RTD, isolated conversion to current or voltage signal, external cold junction compensation terminals. This product requires independent power supply, three-port isolation between input, output and power supply, with online fault self-diagnostics, and can be configured for temperature range, signal type, etc. via PC or handheld programmer.
Note:Three-port isolation between input, output and power supply. 24V DC (or 220VAC) independent power supply; input side connected as thermocouple or RTD, RTD lead resistance ≤20Ω/wire; thermocouple types with external cold junction compensation terminals; output side outputs current/voltage signal to DCS/PLC according to model selection. Temperature range and signal type configurable via PC or handheld programmer. Module indicators: green power indicator, red fault signal. All terminals hot-swappable. Refer to module side silkscreen for specific terminal numbers.
