PSE300 SMC Pressure Sensor Controller 60mA Max 12 To 24 VDC

PSE300 SMC Pressure Sensor Controller

Product Details

Product specifications

1 Operate the controller with the specified voltage. Operation with a voltage beyond specifications can cause malfunction or damage of the pressure sensor controller. Insufficient supply voltage may not drive a load due to a voltage drop inside the pressure sensor controller.

Verify the operating voltage of the load before use.

2 Use the controller within the specified ranges of the measurement flow rate and under the specified operating pressure. Otherwise it can cause damage to the controller and an abnormal measurement.

3 Do not exceed the specified maximum allowable load. Otherwise it can cause damage or shorten the lifetime of the pressure sensor controller.

4 Reserve a space for maintenance. Remember to leave space for maintenance when designing the piping plan.

5 The direct-current power supply to combine should use UL authorization power supply which is the Class2 power supply based on UL1310 or the power supply is using the transformer of a Class2 based on UL1585.

Output Specification

When the lead wire with SMC Power and Output Lead Wire (type ZS-28-A) is used, the colors of wire (Brown, Black, White, Gray, Blue) will apply as shown on circuit diagram.

NPN Open Collector Output 2 Outputs

Max. 30V, 80mA

Residual voltage 1V or less

Analog Output 1 to 5V

Output Impedance Approx.1kΩ

Auto shift function

In case the source pressure fluctuates too much, the controller may not be able to operate normally. Auto shift is provided to compensate for the fluctuation of the source pressure.

While measured pressure becomes standard pressure value when auto shift input is received, this function correct set value of the switches.

With Auto Shift

Set auto shift input as Lo at the time pressure source change, in order to memorize the pressure change and to correct pressure set value, so that correct decision emerge.

Conditions and explanations for auto shift function

1 Keep constant pressure for 5ms or more from the close signal of auto shift input.

2 At auto shift input, the pressure at that time is memorized to [C_5] as corrected value, and the switch operates with the value which applied compensation value to setting value.

Display indicates [ooo] for approx.1 sec.

3 The switch set as auto shift mode at the time of initial setting operates with the value which applied corrected value [C_5] to setting value:
