Advantech ADAM-5018 Analog Input Module

The ADAM-5018 is a 7-channel differential thermocouple analog input module for the ADAM-5000 rack system. It adopts RS485 Modbus RTU and is designed for temperature data acquisition, supporting multiple thermocouple types, mV voltage and current signals.

1. Model Code Definition

ADAM: Series code for Advantech remote I/O modules

50: ADAM-5000 rack backplane series (plug-in design; must be installed on ADAM-5000 series chassis, different from standalone ADAM-4018)

18: 7-channel thermocouple & multi-function analog input

Suffix A2E/AE: Standard industrial version; ADAM-5018P = enhanced version with independent range per channel

Note: Standard ADAM-5018 shares one range across all channels; the 5018P allows separate configuration for each channel.

2. Key Technical Specifications
3. Channels: 7 differential input channels
4. Resolution: 16-bit
5. Total Sampling Rate: 10 S/s (all channels combined, low-speed temperature measurement)
6. Accuracy: ±0.1%FS for voltage/thermocouple mode; ±0.2%FS for current mode
7. Isolation: 3000 VDC optocoupler isolation to protect host and field circuits
8. CMRR: ≥92 dB @ 50/60 Hz, strong anti-interference against power frequency noise
9. Thermocouple Types: J, K, T, E, R, S, B

8. Universal Analog Signals: ±15 mV, ±50 mV, ±100 mV, ±500 mV, ±1 V, ±2.5 V; ±20 mA, 4~20 mA (built-in 120 Ω sampling resistor, no external resistor required)
9. Protection: TVS/ESD, withstand ±35 V overvoltage, reverse polarity protection
10. Operating Environment: -10 ~ +70°C, 5~95% RH non-condensing
11. Communication: Backplane RS485, Modbus RTU protocol
12. Power Supply: 10~30 VDC from rack, typical 24 VDC
13. Hardware & Wiring Guidelines

Terminal: 16-pin pluggable screw terminal; differential wiring: thermocouple positive → CHx+, negative → CHx-

CJC Cold Junction Compensation: On-board cold-junction temperature sensor, automatic compensation, no external compensation required

Wiring Recommendation: Use matched thermocouple extension cables; route cables away from power cables to reduce EMI

Mounting: DIN rail mounting, plug directly into the ADAM-5000 rack slot.

4. Typical Applications

Heat treatment furnaces, ovens, kilns, food sterilization, chemical reactors, multi-point temperature monitoring for HVAC, furnace group temperature collection; paired with PAC/PLC/SCADA host systems for temperature data logging.

5. ADAM-5018 vs ADAM-5018P

6. Alternative Options & Selection Guide
7. In-series Upgrade: ADAM-5018P (preferred for mixed sensor types)
8. Standalone Module (No Rack Required): ADAM-4018+ / ADAM-4019+
9. Next-Generation Bus I/O: AMAX-5018 (EtherCAT, 6-channel thermocouple, high-speed acquisition)

Warning: AMAX-5018 belongs to EtherCAT slice I/O, not compatible with ADAM-5000 RS485 racks.
