1️⃣ 🎯 Purpose:

The RIO-mini DI8 is designed for:

📥 collecting data from 8 discrete inputs (dry contact, 24 V DC);
📡 transmitting information over an RS-485 network using the Modbus RTU protocol;
🛡 monitoring the presence/absence of supply voltage to actuators (e.g., protecting a three-phase motor from a phase break);
🔢 counting the number of equipment activations or as a pulse counter;
🔄 operating as part of industrial automation systems (ACS TP) with controllers, regulators, or SCADA systems.

2️⃣ 🔧 Functional features:

8 independent discrete inputs with group galvanic isolation.
8 independent pulse counters with options for:
- scaling,
- presetting the initial value,
- operation at frequencies up to 20 kHz.
Slave mode in RS-485 network (exchange with PC/SCADA, PLC, or regulator).
Device configuration:
- via USB (direct PC connection),
- via RS-485 (using an adapter),
- using the free MIK-Programmer software.
