APPROVALS
CE, TÜV, UL, C-UL
CONTACTS
3 normally open safety, 1 normally auxiliary closed
LED indicators for status ans supply diagnostic
SPECIAL CHARACTERISTICS
Selectable opposite polarity between channels
With (RS-NAGA) and without (RS-NAGAO) start control
LED

24 V DC (with electronic fuse)
OPERATING VOLTAGE
24, 48, 110-127, 230 V AC (with galvanic disconnection/transformer)
24 V AC / DC (fuse F1) not useable for safety mats
POWER CONSUMPTION
ca. 3,5 VA, 24 V DC: 2W
START UP DELAY / FALLBACK TIME
< 150 ms / < 50 ms
CONTACT CAPACITY max.
6 A, 250 V AC, 250 V DC
CONTACT CAPACITY min. at 24V DC (*)
10 mA
SIMULTANEITY
Simultaneous protective door contacts : ca.75 ms
ENVIRONMENTAL TEMPERATURE
- 25°C to + 55°C
SWITCHING CAPACITY
1500 VA (resistive load), 100W
CONTACT SECURITY
6 A quick acting (normally open), 4 A time lag (normally closed)
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.

CONNECTION DIAGRAM
A supply voltage must be applied to terminals A1 and A2. Once the supply
voltage is applied, 24V DC is available at terminal S11; power LED
illuminates. Terminals S12, K12 and X1/S22 must be connected according
to the application example selected to meet the application requirements.
To start the unit, terminal X2 and X1/S22 must be bridged. At the variation
"with reset-monitoring" (RS-NAGA) the relay reacts after removing the
bridge X2 to X1/S22. At the variation "without reset-monitoring" (RS-
NAGAO) the function starts after bridging X2 and X1/S22. With all of the
above in place safety contacts 13-14, 23-24, 33-34 closed and 41-42 open.
Channel 1 and channel 2 LEDs illuminate. In series to the reset-button at
terminals X2 and X1/S22 an external device can be monitored.
