Core Features
High-Precision Signal Conditioning

Integrated filtering and amplification circuitry ensures accurate acquisition of 4–20 mA and 0–10 V analog signals, making the module suitable for critical measurements such as pressure, temperature, and process variables.

High-Level Electrical Safety Isolation

The 2.5 kV AC isolation design effectively isolates field wiring from control electronics, protecting the system from electrical noise and surges in harsh industrial electromagnetic environments.

PROFIBUS-DP Gateway Integration

Seamlessly interfaces with the IS220PPRFH1B PROFIBUS-DP gateway, enabling reliable, real-time data transmission over the PROFIBUS-DP communication protocol.

Visual Fault Diagnostics

Each analog input channel is equipped with an LED status indicator, allowing rapid identification of fault conditions such as open circuit, short circuit, or overcurrent, thereby reducing troubleshooting time and system downtime.

Scalable System Compatibility

Fully compatible with Mark VIe controllers and distributed I/O architectures. Multiple terminal boards can be deployed in parallel to meet large-scale analog signal acquisition and expansion requirements.
