The LD2100 has the following physical connections:

Figure 2.1

LD2100 Connections

TB1: Input Power

Power can be wired to the LD2100 through TB1. Wire the connections as follows:

TB1-1 24VDC positive (+)

TB1-2 24VDC negative (-)

P1: Input Power

RLE recommends powering the LD2100 with 24VDC wall adapter power supply. This power

supply can be purchased directly from RLE, and is offered as RLE part #PSWA-DC-24. P1 is

the connection for this power supply.

To learn more about connecting power to the LD2100, refer to

Section 2.6., “Apply Power to

the LD2100” on page 19

.

TB2: Cable Interface

SeaHawk sensing cable connects to TB2. Since sensing cable cannot connect directly to a leak

detection controller, the 15-foot (4.57m), non-sensing leader cable (supplied with the LD2100)

must be connected to TB2, and then the sensing cable connected to the leader cable; see

Section 2.5., “Connect the SeaHawk Leak Detection Cable” on page 17

.

TB3: Summary Relay

Terminal TB3 is a Form C summary relay output. This relay provides alarm notification when

a leak, cable fault, or cable contamination is detected.
