Single Pole Solid State Relay 480VAC / 4-32VDC

The SSR-D48 Solid State Relay is a single pole relay for switching resistive AC loads up to 480VAC, controlled by a 4-32VDC input signal. It is suitable for electricians, panel builders and control system integrators needing a reliable, contact-free switching device for resistive loads such as heating elements.

• Application: Contact-free switching of resistive AC loads
• Load voltage: 480VAC (resistive load)
• Control voltage: 4-32VDC
• Poles: Single pole

Key Features

• Solid state switching gives silent, contact-free operation with no mechanical wear
• 4-32VDC control input suits standard PLC and controller output signals
• Available in multiple current ratings to match different load sizes
• A matching heat sink is required to achieve the rated current — plan for this at order stage

Typical Applications

• Heating element and resistive load switching
• Panel builder control circuits
• Industrial process control switching
• PLC-controlled load switching

Technical Specifications

What's Included

• 1 x SSR-D48 Solid State Relay (current rating as selected)

Please note: Heat sink and load wiring are not included unless specifically listed above.

Installation & Compatibility Notes

• For capacitive or inductive loads, the relay must be rated accordingly — confirm load type before ordering.
• A matching heat sink is required to reach the specified current rating; order one if not already fitted.
• Installation should be carried out by a suitably qualified electrician where required.
