24 V DC ( + 25 - 20 % )
OPERATING VOLTAGE
Overvoltage protection
POWER CONSUMPTION
ca. 3 W
START UP DELAY / FALLBACK TIME
<30 ms / <140 ms (single channel <360 ms)
CONTACT CAPACITY max.
total current 1,8 A
CONTACT CAPACITY min. at 24 V DC (*)
infinite
SIMULTANEITY
not necessary
ENVIRONMENTAL TEMPERATURE
-25°C to + 55°C
SWITCHING CAPACITY
to 43 W
CONTACT SECURITY
short circuit proof
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
4 wire technology with wire break protection or 2 wire technology and
terminating resistor with wire break protection are optional. Start
monitoring and automatic start are optional. For monitoring of external
relays to n.c. contacts are put in series of the start circuit "AND"
function among several SAFE C is possible.
