Overview
Discover ARBOR W-M2B502: a compact 4-channel digital input and 2-channel relay output module with Modbus RTU, ideal for industrial data acquisition. Features over-voltage protection and a wide temperature range.
ARBOR W-series remote I/O modules bring field signals onto an RS-485 Modbus RTU bus with 2500 VDC intra-module isolation, a 10-60 VDC wide-range supply and DIN-rail mounting. They are the standard building block for industrial data acquisition, building automation and factory-floor SCADA where a hardened, wide-temperature I/O layer is required.
Key Benefits
2500 VDC field-to-logic isolation protects the controller from ground loops and surges. -25 to +70 °C operation with 10-60 VDC input suits unregulated industrial supplies. Modbus RTU at 1200-115.2 kbps over 1.2 km keeps wiring simple. Channel-independent configuration, watchdog and LED status indicators simplify commissioning.
Applications
Factory automation and machine control · SCADA and remote telemetry · Building and HVAC automation · Energy and utility monitoring · Environmental and process data acquisition · Test benches and laboratory instrumentation
