Digital I/O module

analogEthernetRS-485

Overview
Ultra-slim RESI I/O modules are built for installations where switchboard space is limited or where a small number of remote I/Os is required on a site. 1MU (serial) variants offer RS232 or RS485 physical interfaces and support MODBUS/RTU Slave plus a simple ASCII protocol for integration with media-control systems and IoT controllers (Node-RED, Node.js, Python). Ethernet variants occupy 2MU and support MODBUS/TCP or MODBUS/RTU over Ethernet; the ASCII protocol is supported on all variants. All modules include a wide-range power supply (12–48Vdc).

How to configure?
Use the free RESIConfigurator software to parameterize, configure and test the modules. Each product includes a complete ASCII command list and a MODBUS register table with full explanations to simplify integration.

Interfaces (options)

• RS232 + RS485: ASCII + MODBUS/RTU Slave protocol
• Ethernet: ASCII + MODBUS/TCP Server protocol (or MODBUS/RTU via Ethernet)

Inputs / Outputs (selectable options)

• 2xRI (AC/DC inputs 12–250Vac/dc)
• 4xDI (DC inputs 12–48Vdc)
• 4xDIBI (DC inputs 12–48Vdc, dry or wet contact)
• 4xDO (DC outputs max. 30Vdc, 350mA)
• 1xRO (relay output 250Vac / 30Vdc, 8A)
• 2xRO (relay outputs 250Vac / 30Vdc, 8A)
• 2xSSR-1A (solid state relay outputs 230Vac/dc, 1A)
• 2xSSR-3A (solid state relay outputs 60Vac/dc, 3A)
• 2xSSR-6A (solid state relay outputs 60Vac/dc, 6A)
• 4xAIOX (universal analog I/O: 0/2–10V, 0/4–20mA, RTD, DI)
• 4xAIU (analog inputs 0/2–10Vdc)
• 4xAOU (analog outputs 0/2–10Vdc)
• 2xAIU + 2xAOU (analog inputs + outputs 0/2–10Vdc)
• 2xRTD (RTD sensor inputs: OHM, PT100, PT1000, NI1000-DIN43760, 2/3-wire)
• 1xLED (3x PWM outputs for LED strips, max. 60Vdc, 15A)
• 2xLEDWS (2 channels, 512 LEDs each, for WS28xx intelligent LEDs)
