4.8 External alarm I/O connection

Alarm inputs and outputs are supplied screw down terminal blocks. The screw terminal blocks are supplied with the unit.

Connecting the inputs

Each (alarm) input line can be switched by a contact from an external device between an numbered input and ground (G). Wire them as either Normally Open (N/O) or Normally Closed (N/C). Configure the alarm inputs as N/O or N/C in the menu system. The default is N/ O.

Specifications

Alarm input impedence: Internal pull-up 10 kOhm to +5 V

Input voltage range: -2 VDC minimum to 15 VDC maximum

Input voltage threshold: low voltage 0.5 V maximum, high voltage 2 V minimum

Cable cross section: AWG 26-16 (0.13-1.5 mm2)

Connecting the alarm outputs

The four alarm output relays respond to input alarms and triggers. Configure the alarm outputs as N/O or N/C in the menu system. Only connect resistive loads to the alarm output relays. Do not exceed 30 Vac, 40 Vdc, 500 mA (continuous), or 10 VA on an alarm output relay's contacts.

DANGER!

Electrical voltage.

Risk of electric shock and damage to the unit.

The contacts must not be used at AC line voltages.

Specifications

Switching current (resistive): 500 mA maximum

Switching voltage (resistive): 30 VAC/40 VDC maximum

Cable cross section: AWG 26-16 (0.13-1.5 mm2)
