Smart Relay System eliminates need for standalone controller.

Press Release Summary:

PLC Logic system houses logic in module that plugs directly into block of 8 PLC Relays to create smart relay system. When connected to 8 relays, complete system measures 50 mm wide. Each electromechanical and solid-state relay channel can be configured as input or output, from 16–48 I/O points, with the use of expansion modules. Logic modules have 8 integrated digital inputs, 2 of which can be defined as analog inputs (0–10 V). Hot-swap capability facilitates relay replacement.

Phoenix Contact Introduces Smart Relay System

MIDDLETOWN, Pa. – Phoenix Contact’s new PLC Logic system combines basic programmable logic capability with the company’s PLC relays, creating a “smart” relay system. The PLC Logic system houses the logic in a small module that plugs directly into a block of eight PLC Relays. By eliminating the need for a standalone controller, PLC Logic saves space and simplifies maintenance.

The pluggable logic modules are compatible with a wide range of Phoenix Contact’s electromechanical and solid-state relays and are available in various voltage ranges. When connected to a set of eight relays, the complete PLC Logic system measures only 50 mm wide. Thanks to hot-swappable relay capability, individual relays can be replaced without shutting down the entire system.

Each relay channel can be configured as an input or an output, from 16 to 48 I/O points, with the use of expansion modules. The logic modules have eight integrated digital inputs, two of which can be defined as analog inputs (0-10 V).

With the LOGIC+ programming software, the user can simply drag and drop to configure the system. The software also includes commands for configuring timer, counter, threshold, and more options. It is available as a free download at
