SC3048 Analogue Input Isolator (Intelligent, One-In Two-Out)
Intelligent signal isolation converter, one-in two-out: one current/voltage signal is isolated and distributed to two outputs of different forms, as determined by the ordering code.
- Original Factory Genuine, Tenfold Compensation for Counterfeits
- Full Machine Warranty, Lifetime Maintenance
- In Stock, Shipped on the Same Day
Same as SC3047, single-channel one-in two-out configuration; the signal types of the two outputs can be determined separately via the ordering code. 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. Independent 24V DC (or 220VAC) power supply; the input side accepts DC current/voltage signals per the ordering code; the output side comprises Output 1 and Output 2, with signal types determined separately per the ordering code. Module indicators: green power indicator, red fault signal. All terminals are hot-swappable. Refer to the silkscreen on the module side for specific terminal numbers.
Ordering information:
- When ordering, the input signal, the two output signals and the power supply method must be specified per the ordering code.
- Factory example: 1-5V input, two 4-20mA outputs, 220VAC power supply, model SC3048-2A.
