Technical data

Circuit board dimensions 43 mm x 30 mm
Inputs Safety, SIL 3, Cat. 4

Safe inputs can be configured as 1-channel or 2-channels depending on the desired application or PL and SIL level.

1 x 2 channels
Outputs digital 2 x electronic
Outputs Safety, SIL 3, cat. 4 no local safe output
Safety signal inputs floating contacts
Input voltage (sensor supply)

inputs are supplied by ASi or by AUX (24 V or 48 V auxiliary power). If supplied by ASi, inputs shall not be connected to earth or to external potential.

out of ASi
Output voltage (actuator supply)

Electronic outputs are supplied by ASi or by AUX (24 V or 48 V auxiliary power). If supplied by ASi, outputs shall not be connected to earth or to external potential.

 

For relay outputs the relay contacts are initiated from ASi. The load circuit is powered externally as specified in the data sheet.

PCB connection

Connection possible via wiring pins, screw terminals, solder lugs or connecting wires.

Further connection options are available on request.

connecting wires, 100 mm + contact pins
Coating

Coating protects components and circuit boards when touched. Thick coated and thin coated are available.
 

thick coated
ASi connection

The connection to ASi and AUX (24 V auxiliary power) is made for modules in the active distributor or blue IP67 housing via the yellow or black ASi profile cable with piercing technology or via an M12 plug. Modules for the control cabinet are connected via terminals and PCB modules via wiring pins, connection wires or terminals.


Line protection: If the module is supplied via a M12 connection with A or B coding, it may only be used with a current load of max. 4 A per pin in acc. with IEC 61076-2-101 and IEC 61076-2-109. A fused tap is recommended. There is no such limitation for modules supplied via piercing contacts.
