Vibro-Meter IQS450 204-450-000-002 A1-B21-H05-I0 Signal Conditioner

Base PN: 204-450-000 002

Suffix A1-B21-H05-I0:

A1: Supports TQ401-series probes (0–4 mm span)

B21: Dual outputs 4–20 mA loop & 0–10 V raw bus

H05: Integral 5 m coaxial cable to probe

I0: Standard (no intrinsic-safety barrier)

Drive Voltage: –20 V to –32 V DC (≈ 13 mA)

Measuring Range: 0–4 mm linear (≤ 1 % non-linearity with matched probe)

Frequency Response: DC–20 kHz (captures slow position shifts and high-frequency vibration)

4–20 mA Loop:

Scaled 4 mA @ 0 mm → 20 mA @ 4 mm

Drive up to 800 Ω; < 3 mA indicates open/short fault

0–10 V Raw Bus:

Buffered 0 V @ 0 mm → 10 V @ 4 mm

Output impedance ~ 500 Ω

Cable: 5 m PTFE-insulated, stainless-steel braided coax

Operating Temp: –25 °C to +65 °C; Storage: –40 °C to +85 °C

Shock: 6 g half-sine, 11 ms; Vibration: 5–35 Hz @ 0.15 mm / > 35 Hz @ 1 g

Humidity: Up to 95 % non-condensing

Designed for safe-area use; pairs with external barriers for hazardous zones

Enables both loop-current (4–20 mA) integration into DCS/PLC and raw-bus voltage for VM600 protection cards or data acquisition.

Flat DC–20 kHz response supports simultaneous monitoring of slow shaft drift and high-frequency vibration without external filters.

VM600 form factor allows insertion/removal under power—minimizing downtime during maintenance.

Loop current < 3 mA and raw-bus > 10 V flag probe open/short; front-panel LED shows “OK” vs. fault status.

5 m low-capacitance cable with PTFE insulation and steel braid for reliable performance in harsh industrial environments.

Two TQ401 probes feed IQS450 modules; 4–20 mA loops into the DCS enforce eccentricity interlocks, while 0–10 V raw-bus drives VM600 MPC4 for fast trips if shaft drift exceeds setpoints.

A TQ401 at the compressor impeller face monitors clearance; loop output to PLC triggers load reduction on gap < 0.5 mm, raw-bus 0–10 V feeds CMC16 for trend logging of slow gap changes.
