MECHANICAL SPECIFICATION
FEATURES/BENEFITS
• Mounting and dismounting on DIN rail without
any tool or directly mountable on panel
• Zero-cross and random models; thyristor output
• Large control range with each input
• Green control LED
• Very high immunity
• Low leakage current
• Internal transient suppression
DESCRIPTION
The Series DRD dual-output DIN-rail relays are
designed for all types of loads. The relays utilize
optical isolation to protect the control from load
transients. The DRD relays have an integral heat sink,
and can be mounted and dismounted onto a DIN rail
without any tools. The relays may also be panel
mounted. All relays offer a green control LED and
transient suppression. This dual package allows
users to conserve cabinet space.
APPLICATIONS
• Heating control
• Motor control
• Industrial and process control
APPROVALS
Series DRD relays are pending UL recognition.
