1.4.1 DC POWER SUPPLY REQUIREMENTS
Standard ST-72 power requirements are 10-30VDC @ 12 watts applied to terminals 1 &
3(+) and 5 & 7(-) of TB4 on the standard I/O Board (
see section 3.0 ). Optional features
increase power consumption as described below:

Discrete Relay Board option; add 6.5 watts per board (assumes all 16 relays are
energized).

Programmable Relay Board option; add 6.5 watts per board (assumes all 16 relays
are energized).

Analog Input Board option; add 1/2 watts per board plus transmitter power
consumption.

4-20mA Output Board option; add 2.5 watts per board.

Bridge Sensor Input Board option; add 3 watts max per board with eight 10-0192
modules installed (power consumption of the sensors not included).

Auxiliary Standard Relay Board option; add 2.5 watts.

Isolated Serial Expansion Board; add 1.5 watts.

TB4 terminals 2, 4, 6 & 8 of the standard I/O Board provide a maximum of 500mA
fused output power for powering of auxiliary external devices such as relays, lamps
or transmitters. Power consumed from these terminals should be considered when
calculating system power consumption.
1.4.1.1 600 WATT AC
– 24VDC POWER SUPPLY
*110-120 VAC @8.5A max
*220-240VAC @ 5A max
* Universal AC input automatically selects AC input range.
The 600 watt power supply (Figure 3-7) is for powering the ST-72 and up to 64
detectors. This power supply can be paralleled with up to three additional 600 watt
power supplies providing up to 2400 watts for applications with large power
requirements. It also features a built in DC-OK signal and remote on-off control.
1.4.1.2 150 WATT AC
– 24VDC POWER SUPPLY
*110-120 VAC @3.2A max
