cmi70

• Direct control of synchronous solid-state relays using full-wave drive
• Switchable proportional setpoint input: 4–20 mA, 0–10 V, 0–20 V, potentiometer
• Application:
Control of heating resistors for:
– ovens, oil baths, industrial processes
– climate chambers,
– test benches…..


The CMi70 converter uses a standard analog signal (4–20 mA; 0–10 V; etc.) to generate a logic signal with a duty cycle ranging from 0 to 100% for controlling power units or solid-state relays
used in heating element control.
