- In Stock, Shipped on the Same Day
Dual-channel configuration, two 0/4–20mA input signals each isolated and transmitted, supporting 2 active/passive 4-20mA outputs and bidirectional HART digital signal transmission. Requires independent power supply, with three-port isolation between input, output and power supply.
Note:Three-port isolation between input, output and power supply. 24V DC independent power supply; each of the two inputs connects to a 2-wire/3-wire transmitter (isolated supply provided, open-circuit ≤26V, ≥22V at 20mA); the two outputs are 4-20mA, configurable as active or passive current output, 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).
- Confirm whether each output requires active or passive mode when ordering.
