Do you have the manual ? or can get a pdf off a web ?

It might mean 2 amp 'electro-motive' relay or else.
You need to find out if it is a dry or wet output - e.g does it supply
voltage
and if so - what voltage. If dry, the contacts are thrown - you supply
supply
and the relay coil and sink. This is often done when the relay is far
away.

Remember surge currents - currents of 10x value can occur when the
windings are
cool.
