Same as SC3042, single-channel one-in two-out configuration; the input current signal is isolated and output as two 0/4–20mA signals, with bidirectional HART digital signal transmission. Requires independent power supply; three-port isolation between input, output and power.
Note:Three-port isolation between input, output and power. 24V DC independent power supply; the input side provides one isolated power supply for 2-wire/3-wire transmitters and detects the current signal; the output side has two 0/4–20mA outputs, Output 1 and Output 2 (each RL≤550Ω); bidirectional HART digital signal transmission. Module indicators: green power indicator, red fault signal. All terminals are hot-swappable. Refer to the module side silkscreen for specific terminal numbers.
Ordering information:
- Requires independent power supply (18V DC–60V DC).
- Both output loads must satisfy RL≤550Ω.
