MORE VOLTAGES ON RELAY
MORE VOLTAGES ON RELAY
(OP)
Design prepared by another company provides with a coil 24V DC. plus two auxiliary contacts 120 VDC and two auxiliary contacts 240 VAC .
Something is wrong there. Generally how to solve that problem ? ( according NEC)

As long as the contacts are electrically isolated, ac can be applied to one contact and dc to another contact. But you should verify in the instruction manual. Some relays have limitations regarding mixing of voltages even when contacts are (supposedly) electrically isolated.

My NEC is out of date, but it was allowed if the conductors were insulated for the highest voltage.
