Function

Isolation relay output:

It provides 8 normally open (N.O.) and 8 normally closed (N.C.) relay contacts, with 2 points in each group (a total of 4 groups), supporting independent isolation and suitable for controlling loads of different voltages (10-265V AC or 5-150V DC).

It can be configured as isolated or non-isolated mode through wiring (using 1756-JMPR or a third-party jumper to short-circuit the L1 terminal).

Flexible voltage support:

Support wide voltage range (AC: 10-265V; DC: 5-150V, compatible with various loads.

Each channel supports up to 2 A (125/240V AC or 5-30V DC), suitable for medium and low power devices.

Diagnosis and Safety:

Provide module-level fault reports and on-site diagnosis, and monitor the status of relays and communication health.

Supports Event Sequence (SOE) timestamps to precisely record output changes, suitable for critical applications.

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.

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 high reliability and anti-interference, making it suitable for the petrochemical, power or pharmaceutical industries.

Process Automation

Factory automation: In a distributed control system, decentralized devices are controlled via EtherNet/IP or ControlNet.

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.
