The 4-wire (line/mains-powered) STA models accept a signal input from transmitters, temperature sensors and a wide array of other monitoring and control instruments including:
- Current and Voltage Signals
- Temperature (RTD and T/C) Sensor Inputs
- Resistance and Potentiometer Devices
- Direct Millivolt Sources
