SC3075 Temperature Transmitter (One-in Two-out)
Temperature transmitter one-in two-out: one temperature signal with two outputs, output 2 can be optionally RS485 communication, input type 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 SC3073, single-channel one-in two-out configuration, the signal types of the two outputs can be determined separately by the ordering code, output 2 can be optionally RS485 communication. Requires independent power supply, three-port isolation of input, output and power supply.
Note:Three-port isolation of input, output and power supply. 24V DC (or 220VAC) independent power supply; input side connected as thermocouple or RTD; output side includes output 1 and output 2, signal types determined separately by the ordering code (output 2 can be optionally RS485 communication). Configurable via PC or handheld programmer. 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:
- The sensor type, two output signals and power supply method must be specified when ordering.
- Factory example: Pt100 input, two 1-5V outputs, model SC3075-22.
