4 Channel Solid State Relay

Quad Solid State Relay Controller

4 Channel Solid State Relay Controller

Solid State Relay Controllers have been in the forefront of our relay development for the past few months. We currently offer 4 Channel Solid State Relay Controllers with Bluetooth, 802.15.4 Wireless, 802.11b, XSC and ZB ZigBee wireless interfaces and well as Ethernet, RS232.  Features include LED status lights that light when the relay is in the on position, a power light, and E3C compliance.  38.4K baud is the default baud rate but this device has a user programmable baud rate of up to 115.2 and is compatible with ANY computer or microcontroller capable of delivering RS-232 data.  The 4 channel models are available with your choice of a UXP connector or Analog to Digital inputs. Solid State Relays have a longer life span, faster switching time and are far more tolerant to high induction loads.   
Simply connect the RS232 Relay Controller to the Serial Port of your computer and power up the device. In no time you'll be talking to the board and any attached Expansion Boards. You may also connect to a USB Port using an RS232 to USB Adapter.

Solid State Relay

ADSSR4xProXR 4-Channel Solid State Relay ControllerOur Solid State  Relays feature a wide range of controllers to fit just about any application!   Solid State Controllers are available with your choice of eight channel 8/10-Bit Analog to Digital Conversion or UXP Expansion Port on selected models and all are of course SignalSwitch compatible.  All 4 Channel Solid State models feature the ProXR Command Set and an XR Expansion Port.  Built from the ground up with Expansion in mind, simply Chain the XR Expansion Modules, one after another, to meet your computer controlled switching requirements.

Solid State Relay with Analog to Digital Conversion available on the 4 & 8 channel models Solid State Relay with UPX Expansion Port available on the 4 & 8 channel models Solid State Relay with XR Expansion Port available on the 4 & 8 channel models

Onboard analog to digital conversion is available on selected models of these controllers! This will allow you to:

  • Read light and temperature levels
  • Easily activate relays when A/D limits are reached
  • Detect audio levels in a room when connected to a microphone
  • Read switches, potentiometers, and analog joysticks
  • applications are limitless, and surprisingly easy to integrate
  • Available on 4 & 8 channel models

UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. UXP in the part number allows you to:

  • Add Contact Closure Inputs
  • Add Analog to Digital Inputs
  • Add Voltage Detectors
  • Digital Potentiometer Outputs
  • Available on 4 & 8 channel models

Models with the ProXR suffix will feature the ProXR commend set. The ProXR series will allow you to:
