Noise has been reduced by
approximately 20 dB, using our own
silencing design.
• Twin (1 Form C × 2)
Forward/reverse motor control is possible
with a single relay.
• Sealed construction
• Simple footprint enable ease of PC
board layout

#1 This value can change due to the switching frequency, environmental conditions,
and desired reliability level, therefore it is recommended to check this with the
actual load.
