RELIANCE 57C404C is a digital control board.Here is a detailed introduction to the product:

1.Product Overview

RELIANCE 57C404C is a high-performance digital control board as part of Reliance Electric’s AutoMax series PLC module.It is designed for industrial automation and control systems,providing reliable digital input and output functions to meet various control needs.

2.Main Features

Digital Control:

Provides multiple digital input and output channels for connecting external devices such as sensors and actuators.

Supports high-speed digital signal processing to ensure real-time and accuracy of control.

Network Communication:

The network type is RS-485,supporting communication at a data rate of 9.6 kbps.

The cable length can be up to 4000 feet(1219 meters),suitable for long-distance communication.

Environmental Adaptability:

The operating temperature range is-40 to 85°C,and the storage temperature range is also-40 to 85°C,which can adapt to various harsh environments.

Humidity range is 5%to 95%RH(non-condensing),ensuring normal operation in humid environments.

Physical Features:

Small size of 4.37 x 3.54 x 0.79 inches(111 x 90 x 20 mm)for easy installation and integration.

Lightweight of only 0.25 pounds(0.11 kg)to reduce system burden.

Safety and Protection:

Must be installed in a protective enclosure or combined with other components manufactured to provide safety.

The enclosure or component should provide at least a degree of protection against the ingress of solid objects(such as fingers)less than 12 mm,equivalent to NEMA/UL Type 1 enclosure or IP20 rating.

Installation and Maintenance:

It is recommended to locate the device away from high-voltage components and wiring,such as circuit breakers and fuses,transformers,motor wiring,etc.

Allow 4 inches of clearance on all four sides of each RELIANCE 57C404C backplane for ventilation/cooling.

Sensitive input wires should be placed away from electrical noise wires,such as discrete outputs and AC wires.
