DESCRIPTION
NOTES
1) Line Voltage (nominal): 24 = 240 Vac; 48 = 480Vac
2) Switch Type: D = Zero-cross turn-on; A = Zero-cross, AC control;
R = Random turn-on
The Series DR single-phase DIN-rail relays are
designed for all types of loads. The relays utilize
optical isolation to protect the control from load
transients. DR relays have an integral heat sink, and
can be mounted and dismounted onto a DIN rail
without any tools. The relays may also be panel
mounted. All relays offer a green control LED and
transient suppression.
3) Features: 21 = self turn-on suppression; 22 = 24 Vac control
