Honeywell RP973A1005 /U Pneumatic Three-Port Averaging Relay

AVERAGING RELAY

The RP973 series Averaging Relay is capable of the power balancing in which supply voltage can be distributed to two loads with different power capacity. And the difference of power factor between both channels within 0~10% can be adjusted easily. K3, D5, N1, NC2 contacts are provided.

The Honeywell RP973A1005 /U Pneumatic Three-Port Averaging Relay is a 3 volt DC, 0.1 to 10.0 amp relay with an air inlet, drain and electrical isolating diaphragm. It has normally closed contacts that are normally open upon detection of a sufficient gas concentration. The unit is used on many gas detection systems and for safety applications A three-port, air-blast averaging relay uses a piston-type displacer to meter incoming gas and power its electrical circuitry. This sensing device requires no external sensing elements or indicators because it is an integral

The Honeywell RPA102A1020F/U is a Pneumatic Three-Port Averaging Relay. It is capable of switching a constant flow rate in the range of 20-80 SCFM (0.7-2.6 LPM) The relay operates on 115 Vac 60 Hz electrical power and has 2 contacts rated 10 Amps maximum for resistance less than 800 ohms each contact. This relay also has an Adjustable control pressure control.

The Honeywell RP973A1005/U pneumatic three-port averaging relay is a low frequency averaging relay that offers tolerance and precision. Its solid state design makes it long-lasting, while its 3-channel averaging capability makes the product highly versatile. The product is protected by an NEMA 4X enclosure, has a rugged thermoplastic housing and has two separate 8 mA outputs operating 250 VAC at 30 VDC.

An averaging relay uses sophisticated circuitry to prevent small voltage fluctuations from overriding the reading of a regulated signal. Repair jobs become easier when you can monitor voltage or temperature and react accordingly.

The Honeywell Pneumatic Relay is designed for use as a single-point average sensing in the control and balancing of variable flow compressed air systems. The relay has a low impedance diaphragm actuator that provides a fast response time and a direct coupling method with no auxiliary device required.

The RP973A1005/U is constructed of aluminum alloy. It includes three normally closed contacts and a non-latching indicator lamp. The relay is equipped with an adjustable time delay that ranges from 25 seconds to 2 minutes, 40 seconds; it can be used with any pneumatic control system where a timed cycle is desired.
