  • Mounting and dismounting on DIN rail without any tool or directly mountable on panel
  • Zero-cross and random models; thyristors output
  • Large control range
  • Green control LED
  • Very high immunity
  • Low leakage current
  • Internal transient suppression

DESCRIPTION

The Series DR single-phase DIN-rail relays are designed for all types of loads. The relays utilize optical isolation to protect the control from load transients. DR 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.

APPLICATIONS

  • Heating control
  • Motor control
  • Industrial and process control APPROVALS Series DR relays are pending UL recognition.
