Eaton MTL IOP32D 20kA Dual Loop Surge Protector

Eaton MTL IOP32D Surge Protection Device | Oiltech Controls

Eaton manufactures the MTL IOP series to protect industrial digital and analogue I/O loops from dangerous voltage spikes.

Product Overview

• Oiltech Controls supplies the MTL IOP32D to deliver economical and reliable surge protection for automated control systems.
• The MTL IOP32D hybrid circuit combines 20kA gas discharge tubes with fast-acting solid-state components for high-level safety.
• This specific MTL IOP32D model protects two independent loops within a very compact 12mm wide DIN-rail housing.
• The smart mechanical design allows the device to divert high surge currents safely to ground and reset automatically.

Installation Guide

• Installers must snap the MTL IOP32D onto standard 35mm T-section DIN rail to establish an immediate ground path.
• The single manual clamping operation secures the module firmly and provides the essential high-integrity earth connection.
• Angled wire entry design assists field technicians during installation within tight, limited-space electrical enclosures.
• Removable screw terminal strips allow easy loop disconnection by simply unplugging the header from the module side.
• The 2.5mm² (12 AWG) terminals accept heavy-gauge field wiring for secure electrical connections in harsh environments.

Shipping and Packaging List

• Your shipment contains the factory-sealed Eaton MTL IOP32D surge protection module inside a protective box.
• The package includes the removable plug/header screw terminal strips pre-installed onto the side of the module.
• Oiltech Controls ships all industrial automation orders quickly via reliable express carriers like Fedex, UPS, and DHL.

Selection Guide and FAQ

• Question: How does an engineer choose between the MTL IOP32D and the single-channel IOP32 model?
• Answer: Select the MTL IOP32D to protect two loops in 12mm width, optimizing dense multi-channel cabinet space. Choose the single-channel IOP32 model only when your application strictly requires individual channel isolation and integrity.
• Question: Can the MTL IOP range handle high-current actuator circuits or heavy AC voltage loops?
• Answer: No, the standard MTL IOP32D handles a nominal current load of 675mA for standard I/O signals. You must select the IOP HC32 for 5A loads or the IOP-AC model for 120V/240V loops.
• Question: What is the best engineering practice for grounding these Eaton surge protection devices?
• Answer: Engineers must mount the modules on clean, unpainted T-section DIN rail to ensure low-resistance grounding paths. For highly corrosive or adverse environments, always specify the specially-plated DIN rail version from Eaton MTL.
