RK Electronics

ISR Series Image
  • 2 Independent Relays
  • Low Voltage Design for 12 VAC/VDC or 24 VAC/VDC
  • DIN Rail Mounting
The ISR has two independent outputs to the hazardous area and two independent (dry contact) relay outputs. The outputs to the hazardous area can be switches or, when used with a conductive liquid, electrodes. There is also a supply power LED indicator. The ISR must be located and grounded in a non-hazardous location.
DPM Series Image
  • Single & Three Phase
  • 200 to 240VAC, Single Phase
  • 200 to 600VAC, Three Phase
  • All settings retained if there is a complete loss of power
  • DPM settings can be adjusted while voltage is disconnected
The DPM is a Digital Phase Monitor that will monitor line voltages from 200VAC up to 600VAC. Actual line voltages and set-up parameters are set via the digital display. The supply voltage must be available during operation.
PRRO Series Image
  • 10A relay
  • SPDT or DPDT
  • Pick-up & Drop-out Delays
  • Phase Loss
  • Phase Rotation
  • 240V Control Contact Rating
  • Normal Condition LED
IS-R Series Image
  • Conductivity or Resistance Inputs
  • Output and Input LED Indication
  • 1, 2, 3, or 4 Channels
TUB Series Image
  • Multiple Functions
  • 0.1 Seconds~72 Minutes
  • SPDT Output Contacts
  • Plug In Mounting
  • UL; CSA Approvals
The TUB timer is easily field programmable by the customer. The multiple function and time delay characteristics are selected by connecting jumpers to the TUB's standard socket. The time delays range from .1 to 17 seconds up to 25 seconds to 72 minutes. A benefit is that you can easily program functions and time ranges, but someone else can't change them by flipping a switch.
CJD Series Image
  • Thru hole C-T
  • 2-50A, 5 ranges
  • 10A relay
  • Noise filter
  • Time delay
  • Adjustable setpoint
  • compact design
  • low cost
PVCL Series Image
  • 10A relay
  • DPDT
  • Undervoltage
  • Phase Loss (Single Phase)
  • Phase Imbalance
  • Phase Rotation
  • Pick-up & Drop-out Delays
  • Normal Condition LED
CSRA Series Image
  • 1-30A AC
  • Large diameter thru hole
  • 10A contact
  • Compact design
  • Terminal block
  • Time delays: Inrush by-pass, Nuisance trip
  • Over or UnderCurrent
DPMP Series Image
  • Single & Three Phase
  • 200 to 240VAC, Single Phase
  • 200 to 600VAC, Three Phase
  • All settings retained if there is a complete loss of power
  • DPM settings can be adjusted while voltage is disconnected
The DPMP is a Digital Phase Monitor that will monitor line voltages from 200VAC up to 600VAC. Actual line voltages and set-up parameters are set via the digital display. The supply voltage must be available during operation.
PVCO Series Image
  • 10A relay
  • SPDT
  • Undervoltage
  • Phase Loss (Single Phase)
  • Phase Imbalance
  • Phase Rotation
  • Pick-up & Drop-out Delays
  • Normal Condition LED
