Hey all-
I’m wondering how to enable multiple outputs on the osPID output card. Briefly, I have a water bath heater/cooler that I want to control with the PID. In the existing system there is a commercial PID controller with three outputs – 2 internal relay (alarm) outputs and an SSR driver output. The osPID system should support at least two outputs (on D5 and D6), it would be nice to get them both working simultaneously. Has anyone done this?
In the existing system, the PID trips one alarm output when temp from the thermocouple goes higher than a setpoint, the other alarm is tripped when lower than a setpoint. Since both outputs are tied to the same alarm (and line power killing external relay), I would only need one PID output (the relay on D5) to kill the system at high/low values if the unit can be programmed to do so? Is this possible?
Thanks,
