Dry Contacts
There are 4 dry contact sockets on the Interface Board. The relays can be programmable from Relay
Functions menu (under
Settings
menu). “General alarm, Input failure, Battery failure, Output failure, Bypass
active, Output overload, High temperature” alarms can be assigned to the contacts. Each alarm can be
assigned to separate relays but also one alarm may be assigned to all relays.
Each output socket 3-pin and middle pin is
fix
ed, the upper pin is normally closed and lower pin is normally
open.
You may see the relay numbers as above.
Maximum voltage to be applied to the relay contacts is 42VAC rms (sinus) or
60VDC. Maximum contact current depends on the applied voltage and the
load characteristic. Both maximum voltage and maximum contact current
corresponding to the applied voltage shall not be exceeded.
Free contact relay connection cables shall have a cross-section of 1.5 mm
2
.
Maximum allowed resistive contact currents for several voltages are given on the table below:
Each relay has both a normally open (NO) and a normally closed (NC) contact. One end of these contacts
is common.
Relay functions are described below:
Relay functions can be changed through front panel.
