F3236 Electro-Magnetic Relay

F3236 electric actuator action is generally more sensitive, i.e., the valve position changes in a shorter period of time, the feedback signal belongs to the fast-changing analogue quantities, in the design of the analogue signal processing circuit, the filtering constants of the filter circuit should be as small as possible, and at the same time, pay attention to the selection of fast A/D chips, such as the successive comparison of the type of A/D chip, which can be sampled quickly, so as to achieve timely tracking of changes in the valve position, thus ensuring the Good control effect.

F3236 hardware chain protection has the advantage of timely and reliable, so in the design of the PAT module, the use of limit alarm signals to participate in the chain protection of the output driver: the upper limit alarm input to participate in the increase output hardware chain, the lower limit alarm input to participate in the decrease output chain protection. At the moment when the valve reaches the upper limit or lower limit, the PAT module can be directly truncated through the hardware to increase the output or decrease the output, without CPU processing, so as to achieve timely and reliable.

F3236 module needs to drive the field electric actuator through the relay, so the good or bad of the relay is directly related to whether it can be controlled normally. Compared with the commonly used electromagnetic relays, solid state relays are a kind of non-contact switching control relays assembled with solid components, whose inputs are isolated by photocouplers, and can be controlled by a very small current.
