PSW2100

Supported Applications

The Omega PSW2100 is an electronic pressure switch featuring a display module for field adjustment and configuration. The series supports pipe, container, and differential pressure measurement applications, as well as container level measurement.

Operating Conditions & Performance

The device operates on a 12-30VDC power supply with an aviation plug (M12*1, 5 pins) electrical connection. The maximum process pressure rating is P-MAX: 4 MPa. Storage conditions require temperatures between -40-185°F (-40-85°C) and a maximum relative humidity of 95%. The measurement range setting spans from -99999 to 99999, with configurable display units including kPa, MPa, Pa, bar, mBar, Psi, mmH2O, mmHg, Torr, and Atm.

Alarm Settings Function

The alarm settings function table defines the following configuration parameters:

• SPx (OUT upper limit): Setting range -99999~99999; Upper limit value of transistor output.
• RPx (OUT lower limit): Setting range -99999~99999; Lower limit value of transistor output.
• SPDTx (OUT output delay): 0.0~60.0(S); Delay time before transistor output active.
• RPDTx (OUT reset delay): 0.0~60.0(S); Delay time before transistor output reset.
• Modex (OUT working mode): Configurable modes include no output, measured value > SPx with delay activation, and measured value < RPx with delay reset.

Configuration Options

The PSW2100 series offers multiple output signal configurations including 4-20mA, 1-5VDC, and two-way transistor outputs. The product overview specifies a two-way transistor output (PNP). Available variants include model codes such as PSW2100-005C, PSW2100-035E, PSW2100-1.5KC, PSW2100-400E, and others.

Signal Connection

The aviation plug (M12*1, 5 pins) pinout is defined as follows:

• Pin 1: Power+
• Pin 2: Transistor output 2
• Pin 3: Power-
• Pin 4: Transistor output 1
• Pin 5: *Signal+

The signal connection table details wire colors and connections: brown (terminal 1) for positive power supply, white/blue/black/gray wires connecting to negative signal module or transistor outputs. For a 4-20mA + two-way NPN output configuration, the common port in specific steps is noted as the positive power supply.

Display Configuration

The display mode allows selection of auto optimal display or integer/decimal precision from one to four decimal places. The process unit can be set via codes 0 through 11 corresponding to various pressure units listed above.

Key Product Differences

Variants in the series are distinguished by their specific model suffixes (e.g., -C, -E) and numerical prefixes indicating different configurations or ranges. The active electrical level for transistor outputs is 2V lower than the power supply level; for example, a 24V power supply results in an active electrical level of 22V.

Installation notes indicate that zero point adjustment should be performed after installation to counter mounting position effects and reset annually. The device carries CE certification indicating alignment with EU standards (EMC equipment instructions 2014/30/EU).
