Function

Isolation relay output:

It provides 16 normally open (N.O.) relay outputs, individually isolated (2 points per group, a total of 8 groups), suitable for controlling loads of different voltages (5-125V DC or 10-240V AC).

Supports Dry Contact applications, has high flexibility and is compatible with a variety of actuators.

Flexible voltage support:

Support a wide range of voltages (DC: 5-125V; AC: 10-240V, output current up to 1.5A (120V AC) or 1A (5-30V DC), suitable for medium and low power equipment.

The contact life is long (300 kHz resistive load, 100 kHz inductive load), suitable for applications with frequent switching.

Diagnosis and Safety:

Support module-level fault reporting and on-site diagnosis, monitor relay status and communication health conditions.

Supports Event Sequence (SOE) timestamp, with a synchronization time of 16.7 seconds (based on Coordinated System Time (CST)), precisely recording output changes.

Encrypted communication is carried out through CIP Security (EtherNet/IP) to prevent data tampering.

Modular design

Single-slot module, supporting hot plugging (RIUP, Removal and Insertion Under Power), facilitating maintenance.

Simplify on-site wiring by using RTB (1756-TBCH or 1756-TBS6H) or 1492 IFM.

Supports fault mode (remain final, ON or OFF, default OFF) and program mode (remain final or OFF, default OFF) configurations.

Network integration

Supports EtherNet/IP, ControlNet and DeviceNet networks, and is suitable for local or distributed I/O configuration.

Using the Producer-Consumer architecture allows multiple ControlLogix controllers to share the output state.

Application scenarios

Industrial Automation

Production line control: Drive contactors, motor starters, solenoid valves or indicator lights, suitable for packaging, assembly or material handling systems.

Hybrid voltage control: Supports AC and DC loads, suitable for controlling various devices (such as alarms, pumps, valves).

High-reliability switching: The isolation relay ensures anti-interference and is suitable for the petrochemical, power or pharmaceutical industries.

Process Automation

Factory automation: Control decentralized devices through EtherNet/IP or ControlNet networks, suitable for distributed control systems in large-scale factories.

Key applications: Utilizing SOE timestamps to record critical output events, suitable for security-related systems.

Building automation: Control HVAC systems, lighting or security equipment, and handle various voltage loads.

System upgrade: Replace the PLC-5 (1771-OZL) or CompactLogix (1769 series) output modules and upgrade to the ControlLogix platform to enhance performance and network functions.
