Just purchased a PSW2100-150C, I'm not getting a 4-20mA output, reads 21.1V open circuit and plugged into an measurement unit. Do I need to enable the output? Signal connection diagram is incorrect, Pin 3 RET pin 5 SIG 2 SW2 4 SW1

Asked by: Mark123456
You should not have to enable the 4 to 20mA output. A wiring issue may be causing the problem. Reviewing the manual and will make corrections. Advise you contact us at pressure@omega.com with your contact information so we can respond directly with the resolution of this issue

Is this product capable of external visual warning/monitoring? As in output wired to 2-3 LEDs a couple feet away that read under pressure, good pressure, and/or overpressure? If not, could you point me in the direction of a product that does. Thank you.

Asked by: Greg14
The two on board transistor output can be wired to switch the power being used to drive the unit to also drive external alarm devices.
