Current input isolator, provides 1 channel of isolated power supply for 2-wire and 3-wire transmitters, simultaneously detects the current signal output by the transmitter, and outputs it after isolated transmission, while supporting bidirectional HART digital signal transmission. It features fast response, low temperature drift and high accuracy. This product requires an independent power supply, with three-terminal isolation of input, output and power supply.
Note:Three-terminal isolation of input, output and power supply. 24V DC independent power supply; the input side provides 1 channel of isolated power supply for 2-wire/3-wire transmitters (open-circuit voltage ≤26V, output voltage at 20mA ≥22V) and detects the transmitter current signal; the output side provides 0/4～20mA (RL≤550Ω) to the DCS/PLC AI channel; bidirectional HART digital signal transmission, with pass-through on both input and output sides. Module indicators: green power indicator, red fault signal. All terminals are hot-swappable. The specific terminal numbers are subject to the silkscreen on the side of the module.
Ordering information:
- This product requires an independent power supply (18V DC～60V DC).
- When ordering, confirm whether the connected transmitter is 2-wire or 3-wire and whether the power supply capability is sufficient (open-circuit ≤26V).
