Pretty new to electrical engineering world, so probably rather simple question. I´m designing control system for tractor trailer hydraulic system. The system is 12 V and solenoids what I am using there are 2 A. Also I´m using few digital inductive sensors(IFS241) which output also 12 V. Since There are some logic behind the operations, I was thinking to use 18 V AND CMOS logic gate (NTE4081B) and 20 V NOT CMOS logic gate (CD4069UB) to run relays. But here is the problem that logic gate outputs only 500 mW and already one relay needs 400 mW (DS1E-M-DC12V). Do you have some ideas how to boost this signal, or how I should control the relays with logic?
Thank you for you advice.
