A series of low-voltage, low-current relays provide opto-isolated security for sensitive low-voltage and digital circuit protection and include 10-A contacts for high-power switching applications, says the company. According to the manufacturer, the MR-310 (SPDT) and MR-320 (DPDT) can trip from sources down to 3.2 mA at 5 VDC. The two series of relays allow two differently referenced power sources on the trip and host inputs, the company states. Both are polarity-sensitive and diode-protected, and both are jumper-selectable for dual ranges to optimize power consumption, says the manufacturer. They can be used in building control systems and other applications.
