5400 Series Relays
- Reliable Control Relays
- B/W relays are rugged, heavy-duty construction for reliable service and long life
- Pump Control
- Relays accept two sensor inputs for pump down or pump up control.
- Suitable for many Applications
- Relays are available with intrinsically safe outputs for connection to sensors in hazardous areas.
- B/W Relays are designed to operate from floats or conductivity sensors. They are ideally suited for level control applications such as high and low level indication and pump control.
- B/W relays are available as chassis mount or in NEMA 1, 4, and 4X housings.
Drexelcage™ Level Cage
What is the Drexelcage?
It is a high quality accessory for new construction or for replacement of existing level cages to support the side mount transmitters.The line includes side-side connected cages with a wide variety of connections and ratings.They are available in A106B carbon steel or 316L stainless steel.All cages carry certification to NACE MR-01-75 and are designed to meet ASME Section 8. The standard drain configuration is a 3/4 inch NPTF with a pipe plug. It can be supplied with a suitable flanged configuration as well.An optional, plugged 1/2 inch NPT vent can also be supplied above the upper side connection. After cleaning, all carbon steel Drexelcages are painted on external surfaces and stainless items are shipped in natural condition.
401-0400 Series - Single Channel Receiver
Verify™ loop diagnostics allow remote manual check and continuous selftesting.This Single Channel Receiver supplies a 4-20 mA loop to, and monitors the status of, a two-wire, on/off level control transmitter (RF, or, Ultrasonic Technology).It provides relay indication of loop status, showing loop in 1) normal, 2) alarm 3) fault condition 4) Verify test in progress.Choosing the Verify option provides a remotely activated test which completely and positively checks the spill prevention system, including the loop wiring, sensing element, and final control elements.With the AutoVerify option, a test pulse occurs every ten seconds, signaling the Verify test at the transmitter and duplicating a high level condition at the sensing element. The receiver then checks that the switch has responded properly.If the switch does not respond to the test, the receiver indicates a fault condition in the output loop.The receiver provides DPDT relay output for fault indication. (NOTE: When using the Single Channel Receiver with the Two Wire IntelliPoint product, specify receiver without Verify. Verify is an onboard feature of the IntelliPoint.)
401-900 Series - Universal Process Meter
Perfect for Level & Flow ApplicationsThe 401-900 Series is a versatile full-featured line of 1/8 DIN digital panel meters designed to satisfy both level and flow applications. As a level meter it can display level in up to two scales (i.e. gallons and height), perform pump control alternation of up to 8 pumps, and linearize non-linear input signals such as a round horizontal tank. As a flow rate/totalizer it displays flow rate and total simultaneously from a flowmeter with an analog output, display flow from a differential pressure transmitter, and display open channel flow from weirs and flumes. The 401-900 Series’ specifications and functionality makes it one of the most advanced line of meters available.Multi-Pump Alternation ControlThe 401-900 Series can alternate up to 8 similar pumps for applications where pumps are used to control the level of tanks, sumps, or wells. Alternating pumps helps extend the life of the pumps by evenly distributing the load among the pumps in service. In the application below, two relays are set up to alternate when an on/off pump cycle is completed. Two other relays are used for alarms.
