Thanks for tip. Duty cycle 0-100 % required. cFP-PWM-520 could fit with smaller models. Depending on model we use 8 to 60 V DC. We first settle with smaller models, so not over 30 V DC is needed. Max current to a zone with highest need is 1.3 A and to any small model zone below 0.5 A.
We are building a new measuring and regulation system for our models. NI suggested to use Compact Field Point for our needs. Everything looks fine, but the relay modules (cFP-RLY 421 or 425) are too slow (421 has max 20 operations/s, i.e. 10 times on and 10 times off) for power regulation. Model...
