Siemens SIMATIC ET 200iSP

Check the number of electronic modules and the current consumption:
Table 4-6 Calculation table current consumption
Electronic modules x number
of modules
Operational
current per
module in mA
= Operational current
consumption in mA
Power supply PS DC24V/
PS AC120/230V
x 1 15 mA = 15 mA
IM 152-1PN x 1 200 mA = 200 mA
8 DI NAMUR x 5 80 mA = 400 mA
4 DO DC23.1V/20mA shut down "H" x 2 290 mA = 580 mA
4 DO DC17.4V/27mA shut down "H" x 5 260 mA = 1300 mA
4 DO DC17.4V/40mA shut down "H" x --- 380 mA = ---
4 DO DC23.1V/20mA shut down "L" x --- 290 mA = ---
4 DO DC17.4V/27mA shut down "L" x --- 260 mA = ---
4 DO DC17.4V/40mA shut down "L" x --- 380 mA = ---
4 DO DC25.5V/22mA shut down "L" x --- 310 mA = ---
2 DO Relay UC60V/2A x --- 100 mA = ---
4 AI I 2WIRE HART x 3 280 mA = 840 mA
4 AI I 4WIRE HART x 5 27 mA = 135 mA
4 AI RTD x 5 19 mA = 95 mA
4 AI TC x 3 17 mA = 51 mA
4 AO I HART x 3 295 mA = 885 mA

WATCHDOG x --- 2 mA x DO ** = ---
Total elec‐

Total Current Consump‐
tion
= 4501 mA
max. 31* < 5000 mA
* Without power supply PS and interface module IM 152-1PN, IM 152-1DP
** Functional current consumption of the WATCHDOG module = 2 mA x number of connected digital
output modules
Note
The limit values are adhered to in the example.
Result: The ET 200iSP can be operated with this con󹪝guration.
