100 Ω platinum, 3-wire, α = 0.00385 Ω/°C. Can be extended with a three core shielded or
braided cable of maximum 20 Ω lead resistance per conductor.
Two RTD inputs for the controller plus one independent temperature input for the limiter. In
case it is required, more RTDs can be monitored with optional RMM2 units. All temperature
sensors are permanently monitored for "sensor open" and "sensor break"
RS-485 and Class 1 Bluetooth
ModBus RTU or ASCII. Multi drop / Daisy chain
Shielded twisted pair cable, 0.5 mm² (AWG 24) or larger. Maximum cable length between
should be no more than 1200 m.
Max. of 247 units per NGC-UIT or per communication port
Software programmable via nVent RAYCHEM NGC-CMA-NH or nVent RAYCHEM
NGC-CMA-EX
Through handheld programming device nVent RAYCHEM NGC-CMA2 and a wireless
Bluetooth connection or via RS485 interface and nVent RAYCHEM Supervisor software or
nVent RAYCHEM User Interface Terminal (NGC-UIT-ORD, NGC-UIT-OUT) and customized
nVent RAYCHEM software.
°C or °F, software selectable.
Nonvolatile. There is no loss of parameters after the event of power outage or long term
shut down. Data holding time ~10 years.
