Solid State: A Practical Alternative to Mechanical Relays!

Mechanical Relays have a good home in low-cost control applications.  But for some users, only solid state switching will do.  Solid State Relays are ideal for users who require long term reliability, silent operation, or high induction tolerance.  Many inductive control applications require a solid state relay.  Inductive loads such as Motors, Valves, Pumps, Solenoids, and Large Transformers (including Fluorescent Lighting) benefit from the use of solid state relays because they reduce the chances of the inductive load interfering with the logic of the relay controller.

Setup for our RS232 Relay Controller shown above. Simply connect the Power and the Serial Cables and start sending commands.

About Serial Communications

Our RS-232 Relay Boards are fully E3C complaint, allowing up to 256 NCD devices to share a single RS-232 serial port.  Mix and match up to 256 devices in any combination.  Speak to each device individually or all devices at once.

To control the this Relay Controller,  simply connect a data and ground wire between the Relay Controller and computer or microcontroller. Provide +12 Volts DC to the board, and send ASCII character codes to control the relays.

Even a no-frills design deserves a high-quality driver stage, and that's exactly what we put on our Serial Relay Controllers.  Fast-reacting flyback diodes help shunt dangerous voltages away from the driver circuit.

Features include no-click startup, LED status lights, and E3C compliance.  Relays can be controlled at 9600 baud and the board is compatible with ANY computer or microcontroller capable of delivering RS-232 data.

Quick Start Kits

Also available is our QS12-F6 Quick Start Kit. Kit includes a high quality regulated switcher supply, serial cables, and an RSIO adapter board used to add a standard serial and power connector to this relay controller.

Quick Start Kit: QS12-F6
Quick Start Kits provide everything you need to begin using your RS232 relay controller.  Kit includes a high quality regulated switcher supply, serial cable, and RSIO adapter (shown below).
QS12-F6 $49

NOTICE: Solid State Relays are Silent and Offer Extremely Long Life, but May Not Function Properly when Subjected to Radioactive Environments.  Forced Air May be Required to Achieve Maximum Load Rating.  NCD does NOT Recommend Driving any Relay at Maximum Load.  It is Not Possible for NCD to verify Manufacturer Claims of Load Ratings.  NCD Solid State Relay Controllers have NOT been Tested at the Rated Loads.  Solid State Relays CANNOT be used for Switching DC loads.  Solid State Relays May ONLY be used in AC Switching Applications.  Solid State Relays Require a Minimum Load, and will NOT Function Correctly Unless Minimum Load Requirements are Met.  External Snubber Circuitry May be Required for Certain Applications.  If a Device Turns On, but Does Not Turn Off, this Usually Indicates a Need for a External Snubber Circuit.  This May Indicate Minimum Load Requirements Have Not Been Met.  Please Research Crydom Solid State Relays or be Familiar with this Technology Prior to Purchase.  Please Consult Crydom Engineers to Determine the Best Relay for Your Application www.crydom.com.
