SWRDC Series Time Delay Relay
• M36 DIN Rail Mounting 22.5 MM Wide
• Solid State CMOS Digital Circuitry
• Delay on Operate Timing Mode
• SPDT Isolated 8 Amp Relay Contacts
• Rotary Switch Course Time Setting plus Fine Time Adjustment Potentiometer
• 16 Overlapping Timing Ranges from .1 Seconds to 120 Minutes
•2 LED Indicators; Power On and Output Relay Energized
TIMING MODE:
Delay on operate timing cycle begins upon application of input
power. The relay contacts transfer at the end of the delay period
and will remain transferred until input voltage is removed. Reset
occurs when input voltage is removed.
CONTACT INFORMATION:

Expected Life @ 25°C: 10 Million Mechanical Operations
100,000 Electrical
ENVIRONMENTAL INFORMATION:
Temperature Range: -40°C to +85°C ( -40°F to 185°F )
MECHANICAL INFORMATION:
Termination:
8 Wire Receptacle Type Screw Terminals, 14-26 AWG
Enclosure Type: M36 DIN Rail 22.5 MM Wide Package
Enclosure Material: Grey Lexan (RAL 7035), UL94-V0

TIMING SPECIFICATIONS:
The SWRDC has 16 overlapping timing ranges covering 0.10
secs. to 120 minutes. Timing is user selectable by means of a
16 position rotary switch and potentiometer allowing the time
delay within the range to be set precisely.
