DSP1A-DC24V
SPDT power relay, 24V DC coil, 16A switching, DSP series, PCB mounting, AgSnO2 contacts for high-current applications.
Product Overview
Description
The DSP1A-DC24V is a high-capacity PCB power relay from Panasonic's DSP series, designed for switching loads up to 16A in demanding industrial applications. This SPDT relay features a 24V DC coil and AgSnO2 contacts for reliable switching of high-current resistive and inductive loads.
The SPDT configuration provides versatility for applications requiring switching between two circuits or normally-closed operation. The 16A rating makes this relay suitable for larger motors, heaters, and industrial equipment.
Featuring robust construction and high-quality AgSnO2 contacts, this relay provides long electrical life even under demanding switching conditions. The DSP series is designed for industrial applications requiring higher current capacity than standard relays.

FAE Expert Insights
"The DSP1A-DC24V is my recommendation when higher current capacity is needed. The 16A rating handles larger motors and heaters that exceed the capacity of standard 10A relays. The SPDT configuration is useful for applications requiring both normally-open and normally-closed contacts. I've used this relay in industrial motor control panels and HVAC systems with excellent reliability. The AgSnO2 contacts are essential for motor loads - they resist welding much better than standard contacts. The coil power is higher at 900mW, so ensure your driving circuit can supply sufficient current. For very large motors, consider using this relay to control a contactor rather than switching the motor directly."
