Connector Wiring Convention (3-pin MIL-C-5015)

• Pin A: 4-20 mA Positive Loop (positive with reference to Pin B).
• Pin B: 4-20 mA Loop Return (negative loop return for Pin A and common for dynamic signal).
• Pin C: Dynamic Acceleration Signal (unbuffered, referenced to Pin B).
• Output signal: 4 to 20 mA current loop from Pin A to Pin B.
• Full scale range (-AA 01): 25.4 mm/s (1.0 in/s) ±10%.
• The transmitter output is proportional to RMS vibration levels.

Environmental and Electrical Endurance

• Relative humidity: To 100% non-submerged (no condensation issues).
• Magnetic field immunity: Less than 20 μm/s per gauss peak (50-60 Hz based).
• Isolation breakdown voltage: 600 Vrms ensures safe system integration.
• Excitation voltage range: 12 to 30 Vdc (current limited to 40 mA).
• Compatible with PLC, DCS, and SCADA internal supplies (typically 30-35 mA limited).
• The 177230-01-01-CN requires no external signal conditioning for 4-20 mA loops.
