g) RS-NAGMP / RS-NAGMP.1
Both Emergancy Stop Relays are the follower of the former RS-NAGM. Compared to the RS-NAGM the
RS-NAGMP provides a selectable opposite polarity between channels with the additional terminal T21.
The version RS-NAGMP.1 is terminal and functional compatible to the RS-NAGM and provides no
opposite polarity between channels.
