SOI885070 picture

SOI885070 Diagnostic relay to detect open load circuit or short circuited SSR

The SOI range of solid state relays from Celduc-Relais feature an internal CT to measure load current. The SOI relay gives an isolated solid state status output and visual LED indication when load current is present.

-Control input present and solid state status output = off then load is open circuit
-Control input not present and solid state status input = on then relay is in short circuit

SIL4 / SIM4 DIN rail mount phase control module with heatsink

These phase control modules from Celduc-Relais vary the switching point on a sinusoidal AC supply giving a variable voltage output suitable for controlling resistive heater loads.


Features:

SO3 picture

SO3 Burst control module

The SO3 module features a fast cycle burst mode particularly well suited to low thermal inertia loads such as short wave infrared heaters. It allows fine power control while reducing noise emissions. The control algorithm switches full streams of sine waves equally distributed along a fixed modulation period with on time to off time asa function of the analog input signal.
