Connector
Description
X 16:17:18
System fault's output relay, with a changeover contact. Pins 16 and 17 are closed when the unit has a system
fault or is powered OFF. Pins 16 and 18 are closed when the unit is powered ON and there is no system fault.

The relay's earthing connector.
By default, the CPU module (combining the CPU, the I/O and the power supply) is included in all
AQ-2xx IEDs to provide two standard communication ports and the relay's basic digital I/O. The
module can be ordered to include 2 or 3 digital inputs.
The current consumption of the digital inputs is 2 mA when activated, while the range of the operating
voltage is 24 V/110 V/220 V depending on the ordered hardware. All digital inputs are scannced in 5
ms program cycles, and their pick-up and release delays as well as their NO/NC selection can be set
with software. The digital output controls are also set by the user with software. By default, the digital
outputs are controlled in 5 ms program cycles. All output contacts are mechanical. The rated voltage
of the NO/NC outputs is 250 VAC/DC.
The auxiliary voltage is defined in the ordering code: the available power supply models available are
A (85…265 VAC/DC) and B (18…75 DC). For further details, please refer to the "Auxiliary voltage"
chapter in the "Technical data" section of this document.

Selects whether or not a 30-ms deactivation delay is added to

Scanning cycle
All digital inputs are scanned in a 5 ms cycle, meaning that the state of an input is updated every 0…5
milliseconds. When an input is used internally in the device (either in setting group change or logic), it
takes additional 0…5 milliseconds to operate. Theoretically, therefore, it takes 0…10 milliseconds to
change the group when a digital input is used for group control or a similar function. In practice,
however, the delay is between 2…8 milliseconds about 95 % of the time. When a digital input is
connected directly to a digital output (T1…Tx), it takes an additional 5 ms round. Therefore, when a
digital input controls a digital output internally, it takes 0…15 milliseconds in theory and 2…13
milliseconds in practice.
Please note that the mechanical delay of the relay is no
nott included in these approximations.
