Finder Programmable Logic Relay (PLR) PLC Control Module, 24 V DC, 8 Digital Inputs, 4 Analog Inputs, 4 Relay Outputs, 8 A, LCD Display, DIN Rail Mount, 8A.04.9.024.832C

Equipped with 8 digital inputs, 4 analog inputs (0-10 V, shared with digital inputs), and 4 relay outputs rated at 8 A, this programmable logic relay delivers flexible control for industrial automation. The integrated LCD (4 lines x 18 characters) and 4 function keys allow on-site programming and monitoring without a PC.

Overview

The Finder 8A.04.9.024.832C is a programmable logic relay (PLR) designed for small to medium automation tasks. It operates on 24 V DC and supports Ladder Diagram (LD) and Function Block Diagram (FBD) programming languages, with a program memory of 400 lines (LD) or 300 blocks (FBD). A real-time clock with battery backup enables time-based control functions.
