Key Features

High-Isolation 4-Channel Voltage Input
- Provides 4 independent, fully isolated input channels for simultaneous acquisition of ±10 V DC analog signals.
- Delivers 1500 V AC (RMS) / ±2000 V DC isolation between channels and between channels and the backplane, eliminating ground loops and protecting the system from high-voltage transients.
Ultra-High Precision & Resolution
- Utilizes an 18-bit integrating ADC with 13 bits plus sign usable resolution, capturing subtle signal variations for precise process control.
- Maintains ±0.05% full-scale accuracy and a CMRR of >100 dB, ensuring stable measurements in electrically noisy environments.
Advanced Filtering for Noise Reduction
- Integrates a 1 kHz 3-pole Bessel analog filter and configurable digital filtering (1–128 samples/update) to suppress electrical noise and signal interference.
- Enables stable and accurate data acquisition even in environments with high EMI/RFI interference.
Rugged & Compact Industrial Design
- Constructed with industrial-grade components and a compact, space-saving form factor for reliable operation in harsh conditions.
- Supports a wide operating temperature range of 0°C to +60°C, suitable for factory floors, outdoor cabinets, and extreme industrial settings.
Seamless Series 90-30 PLC Integration
- Designed for direct compatibility with GE Series 90-30 PLCs, enabling plug-and-play installation via the PLC backplane.
- Communicates via the system bus with a fast update rate of 45 channels per second, providing real-time data to the controller.
- Features LED status indicators for power, channel activity, and fault diagnostics, simplifying maintenance.
