PLCs, Power Supplies & Others

The Honeywell 900A01-0102 analog input module delivers versatile signal acquisition for industrial control. This module offers eight fully isolated input channels for precise monitoring. Furthermore, it accepts a remarkably wide variety of signal types directly. Consequently, you can simplify cabinet wiring and reduce inventory for different sensor types.

Unmatched Signal Versatility and Isolation

Each channel on the 900A01-0102 module supports user-configurable input types. Specifically, it handles thermocouple, RTD, resistance, and voltage signals with ease. Moreover, the module accepts millivolt, milliamp, or slidewire inputs for maximum flexibility. Importantly, it provides 400 VDC point-to-point galvanic isolation between all channels. This robust isolation ensures superior data integrity and protects your system from ground loops.

Advanced Technical Performance

The module incorporates a high-resolution 15-bit analog-to-digital converter. This A/D converter updates every 500 milliseconds for timely data acquisition. Additionally, sophisticated noise rejection technology guarantees clean signal readings. The design achieves over 130 dB common-mode rejection at 120 VAC. Therefore, you maintain exceptional accuracy even in electrically noisy plant environments.
