DEVICE SAFE C1
Safety controller for e-stop
APPLICATIONS and gate monitoring applications
APPROVALS CE, TÜV, UL, C-UL
CONTACTS 4 safety semiconductor outputs
LED indicators for status and supply diagnostic
SPECIAL CHARACTERISTICS Wearless contacts, "AND", "OR" functions between several SAFE C1
Automatic start possible
LED Power, channel 1 and channel 2 + flashing code
24 V DC ( + 25 - 20 % )
OPERATING VOLTAGE Overvoltage protection
POWER CONSUMPTION ca. 3 W
START UP DELAY / FALLBACK TIME < 70 ms / < 30 ms
CONTACT CAPACITY max. total current 1,8 A
CONTACT CAPACITY min. at 24V DC (*) infinite
SIMULTANEITY no (special variants possible)
ENVIRONMENTAL TEMPERATURE -25°C to + 55°C
SWITCHING CAPACITY up 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.

CONNECTION DIAGRAM
2-channel e-stop application with monitoring of reset circuit, opposite
channels polarity and contact expansion.
The release button must be attached to the e-stop circuits (S11/S12,
S21/S22) and the start button must be attached to the reset-circuit (S34/A1).
The activation of the semiconductor safety outputs takes place after closing
of the reset circuit (pressing the start button).
By linkage more SAFE C1 with one another safety applications also
complicated, with which different components are to be differently
supervised, can be realized.
For monitoring of the external contactor, the NC contacts of the force guided
contactors must be attached in series to the reset circuit.
