Motor control relays and intrinsically safe relays

Mike Edwards   

Products AutomationDirect ProSense

ProSense phase monitor motor control relays from AutomationDirect provide protection against phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. The 10 A-rated relays, with LED indicator(s), are compatible with Wye or Delta systems and are available in a range of voltage inputs.

The 120 Vac-rated AutomationDirect relays are available in SPDT or DPDT configurations using an onboard switch selects alternating or single-load operation. Pump seal failure relays monitor the shaft seals of submersible pumps.

The relay output can be used to give an alarm indication of a leaking seal. The relay will automatically reset when the fault condition clears.

Macromatic intrinsically safe relays allow control of up to four loads with up to four corresponding discrete input devices (switches, sensors, etc.) in hazardous areas.

The onboard SPST relays operate at either AC or DC coil voltage ratings. All models offer finger-safe design and include LED status indicator(s) and are 35 mm DIN rail or panel mountable.
