Pin Function
Not Connected Optional: 4–20 mA primary output signal
Static 5.12 Vdc Optional: secondary analog output (4–20 mA, 0–5 Vdc, 1–5 Vdc, 0–10 Vdc) or basic alarm
Serial RS-232RX Input Signal Optional: RS-485 A
Remote tare (ground to tare)
Serial RS-232TX Output Signal Optional: RS-485 B
0–5 Vdc Analog Out Optional: 1–5 Vdc or 0–10 Vdc output signal
Power In
Ground (common for power, digital communications, analog signals, and alarms)
