Model CT-IL Current Transformer to 4-20mA Loop
The CT-IL transducer converts the 5A secondary output from a current transformer into a 4-20mA current loop.
  • Connects directly to 5A CT secondary
  • Small size easily mounts onto any CT, 45x30x 41mm
  • Operating range 0-120%
  • Frequency 50/60Hz
  • Powered directly from the current loop

R-ISW Current Switches
DIN rail mounted, circuit breaker sized housing designed to automatically switch on a secondary load when a primary load current is detected. Two different primary load current inputs are available, terminals with a 16A rating or a 6.5mm diameter through hole for 30A circuits.
The basic R-ISW has a current set point of 200mA and an off-delay of 5 minutes.
A programmable version, the R-ISW-A has an adjustable set point 50mA to 200mA (default) and a selectable off-delay of 1 minute, 5 minutes (default) or disabled.
  • Selectable trip point 50mA to 200mA.
  • Selectable off delay time, 1 minute, 5 inutes or off. R-ISW-A
  • DIN rail mounted 17.5mm wide. R-ISW-A
  • 10A/250Vac C/O contact.
    • Gold contact relay versions available
  • 230Vac supply.
