Key Features

1. High-Density 4-Channel Isolated Input
   • Provides 4 independent, galvanically isolated analog input channels for simultaneous acquisition of multiple ±10 V DC signals.
   • Eliminates ground loop interference and protects the control system from high-voltage transients via 1500 V AC / ±2000 V DC channel-to-channel and channel-to-backplane isolation.
2. Ultra-High Precision & Accuracy
   • Delivers 14-bit resolution and ±0.05% full-scale accuracy, capturing subtle signal variations for precise process monitoring and closed-loop control.
   • Features an integrating A/D converter with selectable digital filtering (1–128 samples/update) and a 1 kHz analog filter, ensuring stable readings in electrically noisy environments.
3. Programmable Alarm Setpoints
   • Each of the 4 channels includes a user-programmable alarm setpoint, configured via 4 %AQ output registers in the PLC program.
   • Triggers a corresponding digital input (%I) when the analog input value reaches or exceeds the setpoint, enabling real-time over/under-limit alarm monitoring without additional hardware.
4. Seamless PLC Integration & Hot-Swap Capability
   • Designed for direct compatibility with GE Series 90-30 and PACSystems RX3i PLC systems, with no backplane restrictions.
   • Converts analog inputs to digital values (-32,000 to +32,000) that map directly to the PLC’s %AI table, enabling immediate data access and processing by the CPU.
5. Rugged Industrial Design
   • Constructed with industrial-grade components and a reinforced plastic housing, supporting a wide operating temperature range (0°C to +60°C) and withstanding vibration, shock, and EMI.
   • DIN-rail mountable for easy installation in standard industrial control panels, with a compact footprint saving cabinet space.
