3636R 32-Point Relay Output Module | Triconex

Introduction to the Triconex 3636R Relay Output Module

When your control system must interface with devices that are not compatible with high-side solid-state switches, the 3636R provides a reliable solution. This non-triplicated relay output module is designed for non-critical points, such as annunciator panels, where robust switching is essential.

The 3636R receives output signals from the main processors on each of three channels. These signals are voted internally, and the voted data drives 32 individual relays. This architecture ensures consistent operation even in demanding industrial environments.

Key Features and Technical Specifications

The 3636R offers a range of features that enhance its usability and reliability. Below are the core specifications extracted directly from the datasheet.

• Type: Non-triplicated module for non-critical points.
• Points: 32, non-commoned relay outputs.
• Voltage Range: 155 VAC/VDC maximum.
• Current Load: 2A maximum per output.
• Switching Power (Resistive): 2000 VA, 150 watts maximum.
• Point Isolation: 1500 VDC (2500 VDC for 3636T).
• Fuses: 1 per output, 2.5A fast-acting.
• Diagnostic Indicators: Output Status (1 per point) and Module Status (PASS, FAULT, ACTIVE).
• Output Contact: Normally Open (NO).
• Color Code: Silver Blue.

Each output includes a loopback circuit that verifies relay operation independently of the load. This feature supports ongoing diagnostics and immediate fault detection, which is critical for maintaining system uptime.

Applications and Use Cases

The 3636R is ideal for applications where relay switching is preferred over solid-state outputs. Common use cases include interfacing with annunciator panels, pilot devices, and other loads that require isolated contact closures.

Because the module supports hot-spare configurations, it fits well in systems that demand minimal downtime. The non-commoned design provides flexibility in wiring, allowing each output to be used independently.

Installation and Setup

Installing the 3636R requires a separate external termination panel (ETP) with a cable interface to the Tricon backplane. Ensure that the ETP is properly grounded and that all wiring complies with local electrical codes.

When mounting the module, verify that the chassis slot is compatible and that the backplane connector aligns correctly. After installation, perform a loopback test on each output to confirm proper operation before placing the module in service.

Maintenance and Reliability

Regular inspection of the 3636R is recommended to ensure long-term reliability. Check the status indicators periodically and verify that the fuses are intact. The module's built-in diagnostics help identify faults quickly, reducing mean time to repair.

Because the module supports hot-spare replacement, you can maintain continuous operation even if a module needs to be swapped out. This capability directly reduces downtime costs and improves overall system availability.

Compatibility and Integration

The 3636R is designed for use within the Tricon safety system architecture. It interfaces with the Tricon backplane and works with main processors that provide the three-channel output signals.

For integration, ensure that the external termination panel matches the module's pinout and that the cable assembly is correctly routed. Refer to the official Triconex documentation for detailed wiring diagrams and configuration guidelines.

Troubleshooting and Common Issues

If the FAULT indicator activates, the module's diagnostics have detected an issue. Check the loopback circuit and verify that the output relays are functioning. A blown fuse is a common cause; replace it with the specified 2.5A fast-acting type.

For persistent problems, verify that the input signals from the main processors are present and that the voting logic is configured correctly. If the issue remains, contact AutoDCSTech for technical support.
