Dual-channel configuration, two current/voltage input signals are each isolated and transmitted as two outputs. Requires independent power supply, three-port isolation between input, output and power supply, with online fault self-diagnostics.
Note:Three-port isolation between input, output and power supply. 24V DC (or 220VAC) independent power supply; two inputs connected to DC current/voltage signals respectively according to the ordering code; two output signal types determined by the ordering code. Module indicators: green power indicator, red fault signal. Terminals are hot-swappable. Refer to the module side silkscreen for specific terminal numbers.
Ordering information:
- When ordering, the two input signals, two output signals and power supply mode must be specified according to the ordering code.
- Factory example: two 1-5V inputs, two 4-20mA outputs, 220VAC power supply, model SC3049-22A.
