Expansion module
APPLICATIONS for emergency stop relay according to VDE 0113
APPROVALS CE, TÜV (UL, C-UL pending)
CONTACTS 5 normally open safety and 1 normally safety closed (feedback)
LED indicators for status and supply diagnostic
SPECIAL CHARACTERISTICS Easy way to increase the number of contacts
Compact housing
LED Channel 1 and channel 2
24 V AC / DC (without galvanic disconnection, but with a safety
OPERATING VOLTAGE resistor)
POWER CONSUMPTION ca. 2,4 VA
START UP DELAY / FALLBACK TIME < 30 ms
CONTACT CAPACITY max. 6 A, 250 V AC, 24 V DC, sum of currents <16 A
CONTACT CAPACITY min. at 24V DC (*) 6 mA
SIMULTANEITY
ENVIRONMENTAL TEMPERATURE - 25°C to + 55 °C
SWITCHING CAPACITY 1500 VA
CONTACT SECURITY 6 A quick acting or 4 A time lag
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
Input circuit A1 is to be connected with one of the redundant safety outputs
(13-14). Errors of the expansion unit will be announced over the feedback
control loop (Y1-Y2) and the next activation will be disabled.
In case of protected wiring (short current circuit exclusion) and regularly
tests, for example during maintenance, up to safety category 4.
