Single pole solid state relays with MOV and RC protection from Celduc-Relais
Features:
Single pole solid state relays with MOV and RC protection from Celduc-Relais
Features:
Single pole solid state relays with MOV and RC protection from Celduc-Relais
Features:
Single pole solid state relays with low input current from Celduc-Relais. Multiple relays can be connected to a single PLC or temperature controller output without overloading that output.
Features:
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
Features:
Part no. SOI885070, Current 50A, Order code: 0020590076
Single pole solid state relays with delayed firing from Celduc-Relais
Features:
Single pole solid state relays with DIN rail mount heatsink from Celduc-Relais
Features:
These phase control modules from Celduc-Relais vary the switching point on a sinusoidal AC supply giving a variable voltage output.
Applications:
The SO4 phaqse angle control module allows fine power control with a range of input signals
Features:
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:
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.
Features:
Clip on modules from Celduc-Relais that signal faults and gives outputs
Features:
Features:
Temperature controller, current monitor and communication interface in one unit (option available for the celpac 2G range SU SUL)
The solution for space reduction and wiring simplification !
Pluggable on a celduc® relais SSR type SU and SUL, it can answer the needs of cost reduction of electrical cabinets (smaller), PLC (less analogue and digital I/O’s) and wiring (bus communication).
•Temperature controller with thermocouple input, loop and heater break alarms, heating and cooling PID autotuning …
•Current monitoring and alarms up to 50A with current transformer (CT)
•RS485 communication with MODBUS RTU (others on request)
•J, K, T, E thermocouples
•Auxiliary output for cooling, alarm or 3 phase application control
