HFP Mains Relay Controller With SCI

Model CHQ-MRC2(HFP)-SCI is a mains relay controller providing a single mains rated relay output for the control of such devices as dampers, extractors or plant and equipment shutdown. The monitored input can be used for local power supply fault monitoring or as a general-purpose input.

Also available as a DIN Rail mountable version. Both models feature an integral short-circuit isolator.

Features and benefits:

• Loop powered.
• Single loop address.
• Single mains rated relay contact.
• Relay contact rated at 250 V a.c., 5 A (resistive load only) and 48 V d.c., 2 A (resistive load only).
• Auxiliary monitored input.
• DIN rail version available.
• Both models feature an integral short-circuit isolator.
• Both models approved by LPCB.
• Low power mode (0.75s) 100 μA.
• Quiescent current (typical) 300 μA.
• Current consumption 22 mA ± 20 % (polling).
• Current in short circuit 8 mA.
• Maximum short circuit current 1 A.
• Input EOL resistor 10 kΩ, ±5%, 0.25 W.
• Input threshold level ON=470 Ω, Short cct <50 Ω, Open cct >100 KΩ.
