RXMB - High-speed relay
RXMB 1
The RXMB 1 is a general purpose auxiliary relay offering multiple contact and coil configuration arrangements. Versions of the relay are available as a pin-compatible replacement for RXMA 1 and RXMM 1. Other versions provide up to 4 individual relays in one module, making compact assemblies for auxiliary relay logic etc.
The high-speed of operation allows the relay to be used for trip auxiliary functions. Some versions are available with LED indication. The relay is available in dc and ac versions.
- Wide range of contact configurations
- Pin-compatible with earlier relays such as RXMA 1 and RXMM 1 etc.
- Some versions with indicating LED's
RXMB 2
The RXMB 2 auxiliary relay supplements the RXMB 1 by providing additional usable contacts. The RXMB 2 provides high-speed operation and offers several configurations with regard to number of contacts and coil configurations. One version provides 4 independent relays with two change-over contacts each. Another version provides one relay assembly with 10 change-over contacts. A third relay variant provides 15 contacts.
The relay is available with contact configurations according to the earlier relay type RXMA 2 and may therefor be used when such contact configurations are needed e.g when replacing an earlier standard application.
Please note that the operating times differ and that the new RXMB 2 relay is faster both on pick-up and drop-out. Other operating requirements, such as an elevated pick-up level may be achieved using the RTXV.
- Wide range of contact configurations
- Pin-compatible versions with RXMA 2
- 15 contacts or 10 change-over contacts
- One version with four independent relays, each with two change-over contacts
