with time-delay function
DEVICE SAFE T…
Emergency stop and safety gate monitoring relay with immediate and
APPLICATIONS delayed outputs
APPROVALS CE, TÜV, UL, C-UL
CONTACTS 2 n.o., 2 n.o. start up delayed, 1 n.c.
cross circuit protection or single-channel
SPECIAL CHARACTERISTICS Time delay 0,05s - 600s in 64 steps,
automatic or manually start with start button
LED Power, channel 1, cannel 2, channel 1 and channel 2 time-delayed
OPERATING VOLTAGE 24 V AC / DC ( + 25 - 20 % ) (electronic fuse )
POWER CONSUMPTION ca. 4,8 W
START UP DELAY / FALLBACK TIME < 400ms / < 30 ms / adjustment
CONTACT CAPACITY max. 6 A , 250 V AC, 24 V DC
CONTACT CAPACITY min. at 24V DC (*) 6 mA
SIMULTANEITY SAFE TN: 1s / SAFE TA,TR: 3s / TU: infinite
ENVIRONMENTAL TEMPERATURE - 25°C to + 55°C
SWITCHING CAPACITY 1500 VA (resistive load)
CONTACT SECURITY 3,6A
OPERATING MODE
(*) We offer all devices who have a CONTACT
CAPACITY of min. 100 mA at 24 V DC with
hard gold-plated contacts. In this way the
CONTACT CAPACITY of min. 100 mA is only 4 mA.
Please ask our sales team!
CONNECTION DIAGRAM
When releasing E-Stop button or opening the safety gate (E-Stop circuit are
open) the contacts 13-14 and 23-24 (outputs) open. The contacts 47-48/57-
58 open delayed at the adjusted time.
SAFE TN standby time after applying of the supply voltage < 0,95 s.
Opening of
the E-Stop circuits meanwhile results to failure.
SAFE TA standby time after applying of the supply voltage < 0,95 s.
Opening of
the E-Stop circuits meanwhile results to several activations of the
outputs after the standby time.
SAFE TR restart is possible during standby time.
SAFE TU standby time after applying of the supply voltage < 0,95 s.
Opening of
the E-Stop circuits meanwhile results to several activations of the
outputs after the standby time.
