SIG-5430 / 4-Port Analog Input I/O Gateway

Key features of the SIG-5430

• • Read 4 analog channels and expose values to Modbus/TCP clients (HMI/SCADA/software tools).
• • Select per-channel measurement mode: voltage (0–5V) or current (4–20mA / 0–20mA).
• • Converts analog signals to 12-bit ADC values (0–4095) for precise reading.
• • 1-bit ADC mode supports two-state logic (e.g., hot/cool, dry/wet) and Internet Switch triggering.
• • Supports up to 4 simultaneous TCP connections; free Modbus/TCP tool available (ModMap).

Analog monitoring with optional two-state trigger mode

Use SIG-5430 for continuous measurement (12-bit ADC) or switch to 1-bit ADC mode when you want a simple two-state interpretation. This can be used for remote trigger-style workflows (Internet Switch) where the analog sensor acts like a digital condition.

• • Continuous value monitoring for trending and analytics via Modbus/TCP.
• • Two-state logic for “good/bad” or “dry/wet” style decisions and remote triggering.
