RXMB 2
Features
· Suitable for tripping, blocking, interlocking etc. in protection, control and industrial systems · Indication of activated coils on some versions · High speed operation, down to 4 ms · Contacts for heavy duty or medium duty operation
· Long mechanical life · High resistance to shock and vibration · Semi protected and dust-proof · Low power consumption · Single- and multi-coil versions · Multi-contact versions · Pin compatible with earlier relay types
Application
The relays are intended for installations where high operating requirements exist on operating time, contact rating or else where normal relays of industrial type are not suitable. The relays are especially suitable in protection and control circuits. They are also very suitable for use in high corrosive atmosphere or seismic areas. Tripping, interlocking and multiplying functions are easily achieved with single relays or combinations of relays.
Types RXMB 1, RXMB 2 and RXMC 1 are space saving relays with up to four separate relay units. The relays can be used as position repeat relays, as interposing relays, as supervision relays, in automatic devices and as output relay in relay protection. The relays can replace many other types of auxiliary relays like RXMA 1, RXMA 2, RXMM 1 etc. RXMB 1 variant E can replace RXMK but contact data is different. Each relay consists mainly of a terminal plate with contact pins, a printed circuit board assembly with card-relays and a protective cover. The card-relays are high quality products to guarantee their intended function and a long mechanical life.
Design
The auxiliary relays in the COMBIFLEX system permit interchanging between various types of relays mainly because the coil terminals are connected to the same terminal on the plug-in base of the relay. Furthermore, relays having the same contact symbol can be interchanged without changing any connections.

RXMB 1
RXMB 2
The RXMB 2 has from four to eight relays internally with two change-over contacts each. The relays may be used individually or in parallel for different applications. The relay is available for standard AC or DC supplies. The RXMB 2 has a light beige non transparent polycarbonate cover. RXMB 2 occupies two seats and can replace RXMA 2.
RXMC 1
The relay is designed for dc supply and contains two auxiliary relay units. The RXMC 1 relay is available in two versions, one with 2 NO-contacts per relay unit and another with 3 NO-contacts per relay unit. The contacts of the relays are of heavy duty type. In the version with 2+2 contacts, the coils are provided with built-in series resistors giving the relays a short pick-up time. The relay has one LED per relay unit for indication of energized coil. The relay is available in two variants, one with red LEDs and the other with yellow LEDs.
The RXMB 1 relay is available in different versions. It is mainly designed for dc supply and is built up with card-relay units with different contact symbols as shown below. The contacts are of medium duty type. Variant A of the RXMB 1 relay is provided with built-in series resistors giving the relay a very short pick-up time. This version is suitable for use as a quick-operating trip relay. This relay has one LED per relay unit for indication of energized coil. The LEDs are either red or yellow, according to the ordering table. Variants B-E of the RXMB 1 relay are available with a number of different contact configurations, corresponding to older types of ABB relays, e.g. like RXMA 1 variant C and RXMM 1 variant B. Variants B-E have no indications. Some of these variants are also available for ac supply. Variant F is drop-out delayed, approx. 1 sec.
