Product Description

The Triconex 2770H (277OH) is a high-performance HART interface module designed to bridge intelligent field devices with the Triconex safety platform. It enables bidirectional communication with HART-capable transmitters, allowing the acquisition of secondary variables and advanced device diagnostics without interfering with the primary 4–20 mA safety signal.

Compatible with 3700A and 3721 analog input modules, the 2770H integrates seamlessly into Triple Modular Redundant (TMR) architectures, providing reliable, fault-tolerant digital communication for smart instrumentation while maintaining system safety and integrity.

Key Features

• Supports HART revisions 5.0, 6.0, and 7.0 for broad field device compatibility

• High-density 32-channel interface supporting 4–20 mA loops and 0–5 VDC signals

• Channel-to-channel isolation of 1500 V AC for superior backplane protection

• Low power consumption (<5 W) for minimal thermal impact

• Compatible with 3700A and 3721 analog input modules

• Supports integrated multiplexing (4850 MUX when paired with 2071H)
