“In Service” LED per channel group

Temperature: 0 °C to 60 °C

Humidity: 5–95% non-condensing

High-Density I/O: 32 channels in a single-slot module minimizes rack footprint.

Universal Inputs: Supports both voltage and current signals with jumperless, software-configurable ranges.

High Precision & Linearity: 16-bit resolution and ±0.05% accuracy ensure tight process control.

Robust Isolation: Dual-level isolation protects logic from transients and ground loops.

Configurable Filtering: Per-channel digital filters allow tuning for noisy environments or fast response.

Onboard Diagnostics: Continuous self-test detects open sensors, overrange conditions, and internal faults; status LEDs simplify troubleshooting.

Seamless Integration: Backplane-powered design with direct mapping into the PLC’s data table for easy programming.

Wide Operating Temperature: Industrial-grade tolerances for harsh environments.

Used for torque control of 12 KUKA robot arms, adjusting welding pressure through 4-20mA signal, with accuracy error <0.05%

Deployed in gas turbine auxiliary system, controlling 125 regulating valves through -10~10V voltage signal, achieving oil pressure interlock response time ≤200ms

As the core component of safety interlock system (SIS), output 4-20mA signal to drive emergency shut-off valve, reaching SIL 2 safety level
