Finder 8A.04.9.024.8310 OPTA Plus Series 8A Logic Relay
OPTA PLUS. A range of simple and stand-alone PROGRAMMABLE LOGIC RELAYS ideal for simple applications in industrial automation, OEM and building automation IoT. Programmable with conventional programming languages (ladder logic) as well as with innovative open source programming languages (IDE / ARDUINO). The powerful dual-core Cortex M7 + M4 chip enables a high number of calculations in real time. Thanks to a high-end integrated secure element chip, you can manage encryption and data keys in all types of applications. Supply voltage 12...24 V DC, 8 analog/digital (0-10 V/ 12-24 V) inputs, 4 relay outputs (normally open, 10A), USB (Type C) high-speed port for programming and power supply during configuration, data acquisition (via storage medium), RJ45 Ethernet (Modbus TCP/IP) port and RS485 port for MODBUS RTU connection.
Functions and features:
Finder's industrial know-how is combined with Arduino Pro's open source innovation. Opta is the first programmable logic relay as reliable as a Finder industrial relay. Innovative and connected to Ethernet, Wi-Fi network, Bluetooth® Low Energy technology. Programmable without licenses with Arduino IDE or programming languages such as LADDER, FBD or IEC/EN 61131. Thanks to an integrated secure element chip, it guarantees the highest IoT security.
