Provide fast and reliable relay-to-relay communication for advanced communications-assisted protection, network reconfiguration, pilot protection, and restoration schemes. Modbus, DNP3, and ASCII Protocols Integrate into new or existing networks.

Protect lightly loaded areas of the distribution system and reduce fire dangers with Arc SenseTM technology that detects low-current ground faults typically resulting from downed conductors.

The Type OS2 Release Relay consists of a Mechanism Box (BM) and one or two Safety Manometric Boxes (BMS). Its function is to provoke the activation of a slam shut valve which may be stand alone (Type OSE), integrated in a regulator (Types MP, MPS, DRPNPIL, EZH, DRPN and EZR) or integrated in a Type K1000/K3000, in the case

Air Lock Relay is used to automatically hold the air pressure in control valve diaphragm chamber of the actuator, in an event of failure of air supply.

Feb 24, 2021 · How does an air lock relay works? The airlock relays are designed in a way that, if the headers supply air pressure falls below the cut-off value, then the airlocks trap the air pressure in the diaphragm chamber of the actuator.

Oct 21, 2014 · Failed locked / Drift Open or Close will work based on Fisher lock up relay, which is a pneumatic relay by function. On long run (i.e 2~3 hours), because of leakage of air through the relay, valve will go to its spring driven position, as they are not using any volume bottle (possibly not required by Process to be locked at the last position ...

Mar 29, 2016 · This accessory provides fused terminals in the bottom of the cabinet wired to the voltage inputs and input power on the control module. The terminals for the neutral and drain wires for both Y- and Z-side voltages are not fused.

Mar 26, 2019 · Use the SEL-651R to interconnect microgrids and DERs to area electric power systems (EPSs). It meets and exceeds the requirements for use at a point of interconnection or point of common coupling, per IEEE 1547-2018.

AIR LOCK RELAY AIR LOCK is a reliable unit for achieving stay-put condition of control valves, on air supply failure, The air pressure is blocked inside the diaphragm chamber (or piston cylinder) of the actuator, when the supply air pressure falls below the desired set value. Quality materials are used and each unit is pressure and leak tested, to
