Function description
The contact expansion module is an add­on device without delay­on de­energisation, and it
is used to expand a safety circuit. The contact expansion module is driven by a base unit
(e. g. emergency stop relay).
} Functional procedure after closing the safety contacts of the base unit:
– The supply voltage is present at the input (A1) of the contact expansion module.
– Close the safety contacts 13­14, 23­24, 33­34 and 43­44.
– The LEDs "CH. 1" and "CH. 2" are lit.
} Functional procedure after opening the safety contacts of the base unit:
– There is not supply voltage at input (A1) of the contact expansion module.
– Open the safety contacts 13­14, 23­24, 33­34 and 43­44.
– The LEDs "CH. 1" and "CH. 2" go out.
Installation
} The unit should be installed in a control cabinet with a protection type of at least IP54.
} Use the notch on the rear of the unit to attach it to a DIN rail.
} Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele­
ment (e.g. retaining bracket or an end angle).
} If more than 2 units are installed next to each other in the control cabinet, leave a dis­
tance of at least 6 mm between the units.
