FEATURES/BENEFITS
• Easy mounting and dismounting on DIN rail
without any tools or directly mountable on panel
• Diagnostics offer control and output status
• Tight zero-cross window for low EMI
• 50A back-to-back thyristors
• LEDs for visual diagnostics
• Switch ON in case of overvoltage (DRS24D25)
• Large control range
DESCRIPTION
The Series DRS single-phase DIN-rail relays with
diagnostics are designed for all types of loads. The
relays utilize optical isolation to protect the control
from load transients. DRS 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 control LED and output LED for visual
diagnostics. The DRS provides control and output
transient suppression. A normally closed status output
signal is provided for system diagnostics. The output
will turn on for a short time to clamp high voltage
surges.
