Operating Instructions SWT-1000 DYNALCO

SWT-1000.r2.0609 4

2.2.2 Digital Sensor Connection (IQ)

Frequency range (-3dB) 0.01 Hz / 35 kHz

Input impedance 46 K

Input voltage Max. ± 36V peek

Minimum pulse width Min. pulse width 1.5 µs

Sensor supply +14 V, max. 35 mA short circuit proof.

If the current limit activates, the sensor supply must be disconnected to

reset the protection.

Trigger level

• min.U

low

= 1.6 V

• max.U

high

= 4.5 V

Screen A terminal is provided for the sensor cable screen. This terminal is

connected to the sensor supply 0V. (0VS)

Sensor monitoring 1 of 2 settings may be configured via software:

• No Sensor Monitoring

• Monitoring of powered sensors

[

Also for 2 wire sensors supplied via the Pull-up resistor (Jumper J1)

Æ The sensor is considered to be defective if the sensor current

consumption falls outside of I

min.

= 0.5…25mA

max.

= 0.5…25mA

2.2.3 Binary Input and Push Button

Use For external selection of Parameter set A or B.

• Logic 1 = Parameter set A (Relay control A)

• Logic 0 = Parameter set B (Relay control B)

Levels Logic 1 = V > +3.5V

Logic 0 = V < +1.5V

Reference Sensor supply 0V

Max voltage 36V

Input resistance

min

= 10kΩ

Circuit Internal pull up resistance to 5V

Shorting the binary input to the sensor 0V

creates logic 0.
