IP-1522LR 2 Logic Input x2 Relay Output IO Device

The AtlasIED IP-1522LR Logic / Relay Module is a web-enabled, programmable interface device created to operate as an integral part of an IPX-based InformaCast system. Its compact I/O arrangement combines two electromechanical relay outputs with two optically isolated inputs, giving system designers a focused way to connect remote-control and automation functions to the network. With both PoE and external DC power options, it can be matched to the power approach available at the installation point.

Ideal Use Cases

The model is suited to IPX-based InformaCast installations that need a network-connected path between two logic signals and two relay-controlled circuits. It is particularly aligned with remote-control and automation tasks where a compact, defined number of inputs and outputs is preferred. The two isolated input channels can receive signals across a 4–26 VDC range, while the two relay channels provide Form C contact switching. This makes the module appropriate when the system design calls for paired status or input points and paired control outputs in one programmable device.

Why Choose This Model

The IP-1522LR keeps its function precise: two inputs, two relays, network access, and programmable operation. Each electromechanical relay uses an SPDT Form C contact arrangement. The contacts use AgSnO2 material, have less than 50 mΩ contact resistance, and support a listed maximum of 28 VAC or 24 VDC at up to 3A. On the input side, optical isolation is built into both channels. Together, these characteristics make the unit a cost-effective interface module for a focused two-input, two-output automation task.

Installation and Integration

Network connection is through RJ-45. Power can be supplied by PoE and/or a 9–28 VDC source, allowing the module to follow either documented power method. Power, input, and output wiring terminates at a removable 14-position, 3.81 mm connector. The enclosure measures 3.88 " x 1.41 " x 3.10 " (99 x 36 x 79 mm) and weighs 0.34 lb (0.15 kg), so its physical requirements can be checked accurately during equipment-space planning. Integration should keep relay loads within the listed 28 VAC, 24 VDC, and 3A maxima and input signals within the specified 4–26 VDC range.

Performance Highlights

The module’s two optically isolated inputs draw 950uA at 4V and 8.5mA at 26V. Its two relay contacts use SPDT switching and AgSnO2 contact material, with contact resistance specified below 50 mΩ. These figures provide concrete limits for matching field circuits to the interface. The listed environmental operating temperature range is 40°F to +150°F (–40°C to +65.5°C). For logistics, the shipping package measures 4.5 " x 1.7 " x 3.7 " (114 x 43 x 94 mm) and has a shipping weight of 0.4 lb (0.18 kg).

What Makes It Different

What distinguishes this model is the combination of web-enabled programmability, dual isolated sensing inputs, and dual physical relay outputs in an IPX-based InformaCast component. The two-by-two layout is easy to map to applications that need exactly two incoming logic conditions and two outgoing contact actions. PoE plus the 9–28 VDC power option provides two documented ways to energize the device, while the removable connector places power and field I/O on a clearly specified termination format. The product is backed by a 36-month warranty from the date of purchase.

Final Assessment

The IP-1522LR is a strong fit when the project requirement is specific: integrate two 4–26 VDC optically isolated inputs and two programmable SPDT relay outputs with an IPX-based InformaCast system. Its RJ-45 network interface, PoE or 9–28 VDC power, compact dimensions, and published electrical limits support straightforward selection and system planning. Before deployment, compare connected circuits with the stated voltage, current, connector, and temperature specifications. For installations that match those limits, the module provides a concentrated remote-control and automation interface with a clearly defined I/O count.
