Power supply

For the ease of use in industrial environments, the ADAM modules are designed to accept industry standard +24 VDC, unregulated power.

Operation is guaranteed when using any power supply between +10 and +30 VDC . Power ripples must be limited to 5 V peak to peak while the voltage in all cases must be maintained between +10 and +30 VDC . All

power supply specifications are referenced at module connector. When modules are powered remotely, the effects of DC voltage drops must be considered.

All modules use on-board switching regulators to sustain good efficiency over the 10 to 30 V input range; therefore, we can assume that the actual drawn current is inversely proportional to the DC voltage. The following example shows how to calculate the required current that a power supply should provide.

Assume that a +24 VDC is used for five ADAM-4011 Analog Input Modules, and the distance between modules and power supply is not significant enough to cause a DC voltage drop. One ADAM-4011 module consumes a maximum of 1.2 Watts (W). The total required power will equal to 5 x 1.2=6 W. A power supply of +24 VDC should

therefore be able to supply a minimal current of 6 / 24=0.25 Amps.

Small systems may be powered by using wall-mounted modular power supplies. Also, when modules operate in long communication lines (>500 feet), it is often more reliable to obtain power locally through modular power supplies. These inexpensive units can be easily obtained from any electronic retail stores.

The power cables should be selected according to the length of the power lines and the number of modules connected. When implementing a network with long cables, the use of thicker wire is more suitable due to the limitation of DC voltage drop. Furthermore, long wires can also cause interference with communication wires.
