Module Features & Performance

• High channel density (16 inputs) saves rack space and reduces cost per point.
• Point-to-point isolation (400VDC) prevents cross-talk and ground loop issues between channels.
• Fast 100ms update rate per module ensures timely data for control and monitoring loops.
• High ±15-bit A/D resolution provides fine measurement detail for precise process control.
• Integrated diagnostics monitor module health, power supply, and calibration status.
• Status LEDs provide visual indication: green blinking (active scanning) and red (fault/diagnostic).
• Factory calibration stored in non-volatile memory ensures long-term accuracy without manual recalibration.
• All 16 channels are processed in parallel, preventing increased system scan time as modules are added.

Installation & Wiring Guidelines

• Install in a compatible Honeywell HC900 rack (e.g., 900R04-0300).
• Use appropriate shielded, twisted-pair cable for analog signals to minimize noise.
• For current inputs (4-20mA), ensure loop power is supplied if using 2-wire transmitters.
• Maintain proper cable separation from AC power lines and motor drives to reduce EMI.
• Configure each channel via the HC900 configuration software for the desired voltage or current range.
• After installation and configuration, verify signal accuracy using a calibrated source.
