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.

SP1T RF Pin Diode Switches To 18 GHz
-
Pulsar Microwave manufactures pin diode RF switches that are controlled by TTL logic. This configuration is known as single pole, single throw and is often abbreviated SPST or SP1T. They have been engineered to function in 50-ohm systems, and are designed to operate from 40 MHz to 18 GHz. They have a switching time of 100 nanoseconds and input power rating of 200 mW (23 dBm). Performance of 1.6:1 or better VSWR and minimum isolation of 60 dB is typical of most models.All switches of this type require both +5VDC and -5VDC to operate. Typical current consumption is +/- 30 mA. TTL control logic of 0 to +5VDC is required. Units comes standard with SMA connectors.

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.
