I-7018R 8-ch Thermocouple Input Module, High Voltage Protection, DCON

The I-7018 CR is an 8-channel analog input module from the I-7000 remote I/O range. It accepts voltage, current and thermocouple signals and reports readings over a single RS-485 port using the DCON protocol, making it a straightforward choice for distributed sensor monitoring on serial networks.Inputs can be configured as 8 differential channels, or as 6 differential and 2 single-ended channels. Voltage ranges run from ±15 mV to ±2.5 V, current inputs cover ±20 mA, 0 ~ +20 mA and +4 ~ +20 mA (the latter requires an optional external 125 Ω resistor), and nine thermocouple types (J, K, T, E, R, S, B, N, C) are supported. The 16-bit resolution and ±0.1% of FSR accuracy suit general process measurement.A built-in dual watchdog and 3000 VDC intra-module isolation help keep the module predictable in automated installations. The I-7018 CR is supplied with a blue cover and runs from a +10 ~ +30 VDC supply with reverse polarity protection, mounting on a DIN rail.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The M-7018-G CR is a DIN-rail remote I/O module that takes in eight differential analog channels and accepts voltage, current or thermocouple signals on the same hardware. Readings are sent over a single RS-485 port, so it suits distributed measurement in cabinets and across machines where a serial network is already in place.Each channel supports a wide selection of thermocouple types (J, K, T, E, R, S, B, N and C) as well as a range of voltage and current spans, with 16-bit resolution. Channel-to-channel and module-to-bus isolation of 3000 VDC, together with 4 kV ESD protection on each terminal, help the unit tolerate electrically noisy industrial environments.Modbus RTU and DCON are selectable through software, and the module includes a programmable watchdog for module and communication monitoring.

The M-7018R-G is an RS-485 analog input module with eight differential channels for thermocouple, voltage and current measurement. It suits engineers who need to read temperature sensors and process signals on a networked DIN-rail module, with the option of Modbus RTU or DCON selected in software.Why choose the M-7018R-G: The R variant adds a high level of input protection, with overvoltage tolerance up to 240 Vrms and 200 VDC common voltage protection. Open wire detection for thermocouple channels is software selectable, which helps identify broken sensor wiring. The gray-cover version is the ordering option covered by this listing.Channels can be configured individually, and the module provides 3000 VDC isolation between internal circuits, 4 kV ESD protection on each terminal and a built-in dual watchdog for module and communication monitoring. It is rated for operation from -25 ~ +75 °C.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The I-7018P CR is a DCON-controlled analog input module for engineers who need one unit to handle thermocouple, voltage and current signals. Its eight channels can be configured as 8 differential inputs or as 6 differential plus 2 single-ended inputs using a jumper, and all channels share the same input type.Thermocouple support covers types J, K, T, E, R, S, B, N, C, L and M. Voltage ranges run from ±15 mV to ±2.5 V, and current input at ±20 mA requires an optional external 125 Ω resistor. The 16-bit resolution, ±0.1% of FSR accuracy and 10 Hz sampling rate suit monitoring applications that depend on measurement accuracy.Key protection features include 3000 VDC intra-module isolation, a built-in dual watchdog for module and communication, and reverse polarity protection on a +10 ~ +30 VDC supply. The module mounts on a DIN rail and is rated for operation from -25 ~ +75 °C.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
