M-2000

The M-2004 CR connects four DS18B20 digital temperature sensor ports to an RS-485 network, with each port accepting 2-wire or 3-wire sensor connections. It suits engineers who need several measurement points accessible over Modbus RTU or DCON from a single DIN-rail unit.Each port takes up to 20 sensors and supports cable runs of up to 100 m using daisy-chain wiring. The DS18B20 sensors cover -55 to +125 °C, with ±0.5 °C accuracy specified between -10 and +85 °C and 12-bit resolution at a 1 Hz sampling rate.For electrically noisy plant environments, the module provides EFT, ESD and surge protection, 3000 VDC isolation and a programmable watchdog timer. It operates from +10 to +48 VDC with reverse polarity protection, across an operating range of -25 to +75 °C.ApplicationsMulti-point temperature monitoring in industrial installationsTemperature acquisition over RS-485 Modbus RTU or DCON networks

The M-2017 CR is an 8-channel differential analog input module for engineers who need to read voltage or current signals over an RS-485 network. Each channel can be set to its own input range in software, and the DIP switch selects between voltage and current input for the module.Two sampling modes let you trade speed for accuracy. Normal mode runs at 10 Hz total with ±0.1% of FSR accuracy, while fast mode runs at 60 Hz total with ±0.5% of FSR. The 16-bit resolution applies across the input ranges, from ±150 mV to ±10 V and ±20 mA, 0 ~ 20 mA and 4 ~ 20 mA.The module is built for electrically harsh sites. It tolerates 240 Vrms overvoltage and 50 mA overcurrent at 110 VDC, provides 3000 VDC isolation, and includes EFT, ESD and surge protection to IEC 61000-4-2, -4 and -5. Dual watchdogs for the module and communication help keep a fault-prone installation running.ApplicationsMonitoring voltage and current signals in harsh industrial environmentsRemote analog data acquisition on Modbus RTU or DCON RS-485 networks

The M-2018-16 CR is a 16-channel differential analog input module for RS-485 networks. Each channel accepts thermocouple, voltage or current signals, so one module can cover several sensor types in a single DIN-rail point. Thermocouple channels include open-wire detection, which helps engineers spot a broken sensor loop quickly.Front-end protection is built in. The inputs tolerate a 120 VDC overvoltage and include EMS protection against EFT, ESD and surge events, while 3000 VDC intra-module isolation supports reliable operation in electrically noisy plants. A 16-bit resolution and 0.1% of FSR accuracy give stable readings for process monitoring.Communication uses an RS-485 port that supports Modbus RTU and DCON, with baud rates from 1200 to 115200 bps. A programmable module and communication watchdog helps the module recover from faults, and the unit runs from a +10 to +48 VDC supply across a -25 to +75 °C operating range.ApplicationsTemperature measurement with thermocouple sensors in industrial automationVoltage and current signal acquisition on RS-485 Modbus RTU or DCON networksProcess monitoring in electrically demanding industrial environments

The M-2217CI CR is the eight-channel member of the M-2217CI series, designed to acquire analogue voltage and current signals on an RS-485 network. Each of its eight differential channels can be set in software for voltage or current input, and each channel can be given its own input range, which suits mixed sensor layouts without changing hardware.Engineers typically choose this variant for measurement points where signal integrity and channel separation matter. Channel-to-channel isolation of 3000 VDC keeps neighbouring inputs apart, while 120 VDC overvoltage protection and 50 mA overcurrent protection under 110 VDC conditions help the module tolerate faults on the field side. Time-stamped voltage and current records are stored for each channel, with 320,000 records per channel.Sampling is selectable between a normal mode at 10 Hz and a fast mode at 200 Hz, both expressed as total rates. The module is rated for an input supply of +10 to +48 VDC with reverse polarity protection, and is intended for DIN-rail mounting in an operating range of -25 to +75 °C.ApplicationsAcquisition of analog voltage and current signals from field sensors and transmittersData logging of time-stamped measurements for analysisMulti-channel monitoring on RS-485 networks in demanding industrial environments

M-2217CI-4 is a 4-channel differential analog input module for RS-485 networks, suited to engineers who need electrically isolated measurement channels. Each channel can be set in software for voltage or current input and configured individually for its range, from ±1 V up to ±10 V, or 0–20 mA, 4–20 mA and ±20 mA. Open-wire detection is provided on the 4–20 mA channels.The module offers a selectable sampling rate of 200 Hz in fast mode or 10 Hz in normal mode, with time-stamped recording of both voltage and current values. With 16-bit resolution and an accuracy of 0.1% of FSR, it is a practical choice for multi-point process signal acquisition where data traceability matters.For harsh installations, the module includes 120 VDC overvoltage protection, 50 mA overcurrent protection at 110 VDC (max.), EMS protection against EFT, ESD and surge, and 3000 VDC channel-to-channel isolation. Mounting is on DIN rail, with wall mounting available using the optional ASO-0015 kit.ApplicationsMulti-channel analog sensor and transmitter monitoring in industrial plantsProcess signal acquisition where channels must be isolated from each otherData logging of voltage and current signals with time stampsRemote I/O for RS-485 networks in electrically noisy environments
