Software
Output voltage and current are measured by an integrated module. The module is addressed by a standard
command for the DS2450 module. Data output is provided either as Integer values (0 - 4095) or direct voltages,
depending on the used software product. Please refer to the following formulas depending on the data output:
Calculation with output of DS2450 values in Integer
DS2450, 5 V range, output Integer 0-4096 (12 Bit resolution)
voltage 5 V = ((5,0 / 4096) * 1.11) * DS2450_Port3
voltage 12 V = ((5,0/ 4096) * 2.63) * DS2450_Port1
current 5 V = (5,0 / 4096) * (DS2450_Port2
– 20) * 46
current 12 V = (5,0 / 4096) * (DS2450_Port0
– 20) * 46
Calculation with output of DS2450 analog values in mV
DS2450, 5 V range, 12 Bit resolution
voltage 5 V = (DS2450_Port3 * 1.11) / 10
voltage 12 V = (DS2450_Port1 * 2.63) / 10
current 5 V (mA) = DS2450_Port2 / 20
current 12 V (mA) = DS2450_Port0 / 22

Connection plan
A connection plan and a connection example with further modules are available in our webshop.
Pin assignment input, power supply, Bus Coupler/Controller
14 = plus supply voltage
15 = minus supply voltage
16 = grounding (PE)
23 = Ground 1-Wire input
24 = 1-Wire data line
25 = 5 V input from master (e.g. 1-Wire
Controller or 1-Wire Bus Coupler)
Pin assignment output, 1-Wire
network
1 = Ground / GND
2 = 1-Wire data line
3 = 5 V output maximum 0,5 A
4 = 12 V output maximum 1 A
5 = Ground / GND
6 = 1-Wire data line
7 = 5 V output maximum 0,5 A
8 = 12 V output maximum 1 A
9 = Ground / GND
10 = 1-Wire data line
11 = 5 V output maximum 0,5 A
12 = 12 V output maximum 1 A
13 = not connected
The "1-Wire Bus output 1" is specially designed to supply modules close to the 1-Wire Hub III.
This output
is equipped with a cable length-compensation compared to cable lengths of the outputs 2 and 3.
Note:
5 V input voltage (terminal 25) is available at the output as "emergency power supply" even in case there is no 24
V power supply available at the output of the 1-Wire Hub.
Note: You can find the basics and tips for the 1-Wire Bus system in the ESERA Online Shop at
1-Wire basics or please refer to our eBook in the shop under Training/Documentation
