SC3012 switch input isolator (one in, two out, relay output)
Single-channel one in, two out switch input isolator: one dry contact signal is isolated and output as two relays; the second channel can be set via DIP switch to signal output or fault alarm output.

Same as SC3011, single-channel one in, two out configuration; the second output function can be set via DIP switch to relay 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 dry contact switch or NAMUR proximity switch; output side includes output 1 and output 2 relay contacts; the second output function is set via DIP switch to signal output or fault alarm output. Module indicators: green power indicator, red fault signal, yellow channel status. All terminals are hot-swappable. Refer to the module side silkscreen for specific terminal numbers.
Ordering information:
- Requires independent power supply (18V DC~32V DC).
- The second output function (signal output/fault alarm output) must be confirmed via DIP switch at ordering or before commissioning.

- One in, two out dual relay output; the second output function can be set via DIP switch to signal output or fault alarm output
- The same dry contact/proximity switch signal can be sent simultaneously to both DCS and PLC systems for sharing
- DIP switch settings for non-inverting/inverting logic (default non-inverting), line fault monitoring (default enabled)
- Online monitoring of input open circuit/short circuit; on fault, output opens and indicator flashes
- Three-way isolation between input, output and power supply; no grounding required
- DIN rail mounting, hot-swappable terminals
One signal shared by two systems
The same dry contact/proximity switch signal sent simultaneously to DCS and PLC; or one signal output and one fault alarm output
