SPDS wireless adaptor- User Manual Page 6

5. SPDS vapor pressure valve wireless adaptor

Product Part No. IGSPV40xxx

5.1. General

Adaptor shape is similar to the DataSeal enclosure with the required

modifications for cable connection. RF channels specifications are identical

to the DataSeal.

The adaptor controls the relay of the pneumatic system and reads the

status of the air pressure.

5.2. I/O’s

The adaptor has one input, one output and internal reed switch. The

internal reed switch is used to sense removing of the enclosure from

installation fixture. A magnet should be installed in the fixture. See figure 1

and 2 for reed switch location. NCND D4X5mm magnet is recommended.

Locate a magnet in one of reed switch ends.

The input can be configured to work in digital mode or analog mode. Digital

mode gives the basic ON/OFF functionality without tamper proof of the

cable. In analog mode, the sensor ON/OFF states are sensed and cable

short or disconnect are sensed as well.

To work in digital mode simply connect the sensing switch to the cable.

To work in analog mode connect the sensor according to Figure 3.

5.3. Output specifications:

The output is open drain type with specifications as follows:

 Output type: Open-drain.

 Maximum load: 24VDC relay with 230Ω minimum resistance.

 Maximum open circuit voltage: 32V.

 Functionality: ON- Pulse with configurable width.

 Maximum ON pulse width: 10Sec.
