Frequently Asked Questions
What thermocouple types does the ADAM-4118-C support?
The module supports eight thermocouple types: J, K, T, E, R, S, B, and N. This versatility allows seamless integration into diverse temperature monitoring applications, from cryogenic systems to high-temperature industrial processes. Each channel can be independently configured for your specific thermocouple type.
How does the 3000 VDC isolation protect my system?
The 3000 VDC galvanic isolation prevents ground loops and protects sensitive equipment from voltage spikes and transients. Combined with 4 kV surge, 4 kV EFT, and 8 kV ESD protection, this remote I/O module safeguards your entire measurement chain in electrically noisy industrial environments.
Can I use the ADAM-4118-C in extreme temperature environments?
Yes. The module operates reliably from -40°C to +85°C, making it suitable for outdoor installations, cold storage facilities, and high-temperature industrial zones. This wide temperature range ensures consistent performance across demanding applications without environmental derating.
What communication options are available for remote monitoring?
The ADAM-4118-C offers Modbus/RS-485 connectivity with both RTU and ASCII command support, plus Micro USB for local configuration. This dual-interface design enables flexible deployment in legacy industrial networks and modern IoT ecosystems alike.
