SC3014 Switch Input Isolator (One-In/Two-Out, Transistor Output)
Single-channel one-in/two-out switch input isolator: dual transistor collector outputs; the second channel can be set via DIP switch as signal output or fault alarm output.
- Original Factory Genuine, Tenfold Compensation for Counterfeits
- Full Machine Warranty, Lifetime Maintenance
- In Stock, Shipped on the Same Day
Same as SC3013, single-channel one-in/two-out configuration; the second output function can be set via DIP switch as transistor output or fault alarm output. Requires independent power supply; three-way isolation between input, output and power supply.
Note:Three-way isolation between input, output and power supply. 24V DC independent power supply; input side connects to a dry-contact switch or NAMUR proximity switch; output side comprises output 1 and output 2 transistor collector outputs. Module indicators: green power indicator, red fault signal, yellow channel status. All terminals are hot-swappable. Refer to the silkscreen on the module side for specific terminal numbers.
Ordering information:
- Requires independent power supply (18V DC~32V DC).
- The second output function must be confirmed via DIP switch.
