3. Q4C-II Specifications

NOTICE:

Installing or using this equipment in a manner not specified by the
manufacturer could cause electric shock, bodily injury, or risk of fire.

Specification:

Power Supply

Voltage: 24VDC nominal, range 18 to 30VDC
24VAC nominal, range 15 to 24VAC 50/60HZ

Note: Q4C-II has full-wave rectifier and half-wave rectifier circuit on
board for flexibility.

You will damage devices if you mix half wave and

full wave rectifiers on the same AC source. Use extreme caution when
sharing a common AC source. Sharing a common DC source is less
problematic.

Current:

Q4C-II: max. 0.75 A (fuse protected)

Strobe & Horn: max. 0.25 A (fuse protected)

Note:  No  external  over-current  protection  is  required.  Over-current
protection  is  provided  by  means  of  fuses  F1  and  F2/3.  See  fuse
specification below.

Fuse

F1 on I/O Board for Q4C-II:                                   Polyswitch 750mA
F2 / F3 on I/O Board for Strobe/Horn output:  Polyswitch 250mA

Polyswitch  device  resets  after  the  fault  is  cleared  and  power  to  the
circuit is removed

Enclosure

IP66 & NEMA 4, 4X, 12 & 13 ratings
UL listed 508 listed (File # E65324)

On-Board Relays

4 Relays SPDT, Dry contacts, Relay1 to Relay4
Resistive load:
            5.0A at 250VAC
            5.0A at 30VDC
Inductive load:
            3.7A at 250VAC
            3.7A at 30VDC
