Schneider 12A 24VDC Miniature Plug-In Relay RXM2AB1BD

Miniature Plug-in relay - HARMONY RXM 2 C/O 24 V DC 12 A
RXM2AB1BD

RXM miniature relays are part of Harmony Electromechanical Relays. This is a plug in relay to be mounted on a RXZE socket. It is a 2 C/O relay with current rating of 12A, control circuit voltage of 24 V DC. It also offers one-step loackable test button and mechanical indicator for contact status. The testbutton is activated momentarily by pushing the blue pushbutton on the front and locked by flipping up the green part. The mechanical indicator is next to the testbutton, where an orange flag indicates the relay contact status. Workablity for hard-wired logic automated systems to complement the functions of industrial progammable logic controllers (PLCs). Its design is fit for industrial machines, packaging, textile, HVAC, automation control panels, low/medium voltage switchgear, motor controls, PLC Interfaces, power supplies, building or medical equipment, lighting controls. This product conforms to international standard and certifications like IEC, CE, UL, CSA, EAC, Lloyd's, RoHS and REACH. RXM Relay should be used with a RXZE socket (screw clamp, screw connector, push-in terminal). To protect against vibrations, plastic/metal clamp can be added to the socket. Protection modules and marking legend are also available. It is sold in lots of 10 and reference includes relay only. The RXM plug-in relays are a series of industrial plug-in relays designed for both simple and complex automation systems and available with 2 CO (12A), 3 CO (10A), 4 CO (6A) contacts, 4 CO (3A) low level contacts.

Electrical Durability of Contacts
Durability (inductive load) = durability (resistive load) x reduction coefficient.

Note : These are typical curves, actual durability depends on load, environment, duty cycle, etc.
For inductive load, to increase relay life cycles, please add a proper load protection circuit (eg: RC protection/Varistor/free Wheeling diode -DC load only- ).
For low level loads (below 10mA), we recommend to use RXM*GB series with bifurcated contacts relays instead.
