POWER SUPPLY REQUIREMENTS
ViewSmart 200 primary power may be either 10-30 VDC or 100-240VAC. AC power
requirements are 100-240 VAC 50/60 Hz @ .80 amp max (including inrush) and 40 watts
max steady state, applied to TB5 on the motherboard. If AC power is not available the
primary power may be 10-30 VDC applied to TB1 on the motherboard. A back-up DC
power source may also be connected to TB1 for automatic switchover if the AC power
source fails. See Figures 3.0 & 3.1 for wiring information.
The basic ViewSmart 200 consumes only 1.5 watts of 10-30 VDC power. Optional
features such as relays and analog outputs increase power consumption as described
below:
10-0221-2,
Analog Input PCB
option; add wattage for each monitor connected to
this board’s 24 VDC terminals.
10-0222,
Discrete Relay PCB
option; add 1.5 watt.
10-0223,
4-20mA Output PCB
option; add .5 watt.
10-0219,
Bridge Sensor Input PCB
option; add wattage of each sensor attached.
With an AC primary power source connected to TB1 on the motherboard, TB3 terminals
1 & 2 on the motherboard provide a maximum of 12 watts output power for powering of
auxiliary external devices such as relays, lights and monitors (see Figure 3.0). Power
consumed from TB3 must be included when calculating system power consumption.
IMPORTANT!
TB3 only provides 24VDC power when AC is primary power.
24 VDC terminals on the 10-0221 Analog input option (see Figure 3.3) may also be used
to power external transmitters and these loads must be calculated into the overall power
budget. These terminals receive power from both the integral AC / DC power supply and
the external TB1 supply as shown in Figure 3.0.
Some applications may require 24VDC power in excess of that available from the
ViewSmart 200’s integral AC power supply and thereby require an external AC/DC
supply. NEC Class 2 FIFTY WATT external supplies are available for Division 1 (part #
10-0314) and Division 2 (part # 10-0315) potentially hazardous area installations and
both also include a NEMA 4X weather rating.

RELAYS
Two mechanical (dry contact) Common Form C relays are standard and may be mapped
to various alarm events as described in section 2.3.1. ViewSmart 200s may also be
equipped with optional solid-state common Form A relays (see order guide for details) in
applications requiring non-arcing switching. Solid-state relays are recommended for
switching of highly inductive loads.
