Input Voltage: 24 VDC ±10% (nominal)

Discrete I/O: 16 optically isolated discrete inputs (24 V sink/source); 16 solid-state discrete outputs (0.5 A per channel max)

Analog Inputs: 8 channels, factory-configured for high-performance signal conditioning

Analog Input Impedance: >10 MΩ differential

Analog Input Accuracy: ±0.05% of full scale at 25°C; ±0.1% of full scale across 0°C to +60°C

Resolution: 12-bit (4096 counts)

Signal Conditioning: Precision gain resistors, low-drift amplifiers, overvoltage and reverse-polarity protection

IONet Termination: Internal 120 Ω resistor factory-enabled (eliminates external terminators at end-of-chain)

Analog Outputs: 2 channels, 0–20 mA or 0–10 V (jumper-selectable)

Communication: GE IONet proprietary protocol at 2 Mbps

Isolation Voltage: 1500 VAC (field-to-logic)

Operating Temperature: 0°C to +60°C

Storage Temperature: –40°C to +85°C

Humidity: 5% to 95% non-condensing

Power Consumption: 7.0 W typical

Dimensions: 18.5 cm × 12.7 cm × 3.0 cm (standard Mark VI form factor)

Material & Construction: FR-4 multi-layer PCB with conformal coating; surface-mount precision components; DIN/chassis mounting within Mark VI rack

Working Principle: Field analog signals are conditioned on-board through precision gain stages and low-drift amplifiers, converted via 12-bit ADC, and transmitted over IONet to the Mark VI controller; the ‘D’ suffix permanently enables a 120 Ω termination resistor across the communication pair.

Installation Requirements: Mount in a standard Mark VI rack slot; ensure 24 VDC ±10% supply; verify firmware revision compatibility with the existing Speedtronic toolbox.

Usage Notes: Not hot-swappable — full rack power-down is required before removal or insertion. Confirm the exact analog input type (voltage, current, or RTD) with the OEM datasheet, as the HPID variant is factory-configured for specific sensor scaling.
