Base LD-1150-LV Base Module Assembly

The Base LD-1150-LV Base Module Assembly is the low‑voltage foundation of the LD-1150 family, designed to mount in an Allen‑Bradley I/O chassis and interoperate with other LD‑1150 modules for compact automation wiring. It provides an output relay with a common, normally open, and normally closed contact configuration, plus two loop input channels to monitor sensor or process signals. In the LV variant, power is applied on pin 1 as +12 to +24 VDC or 24 VAC, with pin 2 serving as the return (DC ground or 24 VAC minus); pins 3 and 4 are not connected, and pin 11 is also unused. The relay wiring uses pin 5 as the common, pin 6 as the normally open contact (which closes for DETECT), and pin 10 as the normally closed contact (which opens for DETECT). Pins 7 and 8 accommodate the loop input signals, enabling status monitoring integrated with the control logic. This base module is part of a broader LD‑1150 series that also includes high‑voltage variants; for HV versions, the power inputs switch to AC line on pin 1 (89 VAC to 270 VAC) and AC neutral on pin 2, with the relay and loop‑input layout remaining consistent. Typical applications involve signaling and interlock logic in sensing networks or automation panels, where the LD‑1150‑LV base module provides a compact, reliable interface between sensors, control circuitry, and external indicators or actuators.
