Function description
The contact expansion module is an add­on device with 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).

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).

Power
The supply voltage is present at the input (A1) of the contact expansion module.
Close the safety contacts 17­18, 27­28, 37­38 and 47­48.
The LEDs "CH. 1" and "CH. 2" are lit.
There is not supply voltage at input (A1) of the contact expansion module.
Safety contacts 17­18, 27­28, 37­38 and 47­48 open after the delay time.
The LEDs "CH. 1" and "CH. 2" go out.
