GE IS220PAICH2A Analog Input I/O Pack

1. Market Position

IS220PAICH2A is the high-performance analog input slice for Mark-VIe, targeting SIL 2 safety loops, high-accuracy metering and 50/60 Hz noise rejection. It can directly replace PAICH1A when higher measurement quality is required.

2. Hardware Specification

ü Channels: 16 differential analog inputs

ü A/D resolution: 24-bit Σ-Δ with 50/60 Hz digital filter

ü Input ranges: ±20 mA, ±10 V, TC, RTD (auto-ranging)

ü Scan rate: 100 Hz per channel (10 ms board-level)

ü Isolation: channel-group 2 500 V rms (4 ch per group, 4 groups total)

ü Accuracy: ±0.05 % of span @ 25 °C

ü Protection: ±40 V over-voltage, 50 mA over-current, 2 kV surge

ü Front ports: 2×RJ-45 (100 Mbps TSN-IONet), IEEE-1588 time-sync, 3×LEDs

ü Power: +5 V @ 1.0 A from back-plane; 5 W typical

3. Value-Added Features

² On-board HART multiplexer for smart-transmitter digital diagnostics

² Dual Ethernet ports supporting PRP/HSR zero-loss redundancy

² SIL 2 (IEC 61508) certified by TÜV for direct use in safety instrumented functions

4. Typical Applications
