2.4.9 Interposing Relay Panel
For applications requiring heavy-duty control ratings, the D20K can be connected to field
equipment through interposing relays. The standard D20KI interposing relay panel is equipped
with P&B KUEP and KUP interposing relays (10 A at 150 VDC and 10 A at 240 VAC
respectively). It is used in conjunction with a D20KR termination panel, as shown in Figure 35.
