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.
