PXI Relay Module
Relay
PXI Relay Modules consist of multiple independent relays, such as single-pole single-throw (SPST), single-pole double-throw (SPDT), and double-pole double-throw (DPDT) relays. PXI Relay Modules use a variety of relay types, including electromechanical armature relays, reed relays, field-effect transistor (FET) relays, and solid-state relays, each with their own benefits, allowing you to choose a set of relays that fit your requirements. To program the relays, you can use the IVI-compliant NI-SWITCH driver software, complete with help documentation, example programs, and a soft front panel application for interactive control. For intelligent management of complex switch systems, NI Switch Executive provides additional software tools to help you design, build, and deploy your switching system.

Signal Splitters
-
The DAT4530 can convert any process signal (Thermocouples, RTD, mV, Voltage, mA Resistance and Potentiometer) to a voltage or current output (4-20mA, 0-20mA or 0-10V). Each output can be different and it also has a built in limit alarm which is an SPST relay. The DAT4530 is PC programmable with the aid of the Prodat programmer and the Datasoft software which is available from the Datexel down load page. The DAT4530 is also programmable with the aid of 3 DIP switches which can be found on the side of the DAT4530. There is full isolation between the input, power supply, limit alarm output and two outputs.

Level Monitoring
-
Magnetic level switches are used for the monitoring and control of liquid level in tanks. These level switches are specifically manufactured to customer specifications. The float switches are manufactured with a hermetically sealed contact which is located within the guide tube. The float sliding on the tube contains a ring magnet which activates the sealed contact in a non-contacting fashion. The sealed contacts are available as SPST (N/O or N/C) or SPDT (N/O + N/C). The float sliding up and down on the guide tube is the only moving part on the M-series magnetic float switches.
