Product Description ADS-DM201 is a universal input single channel digital ADC module. It has a universal input function and can receive various types of input signals, including thermocouples, thermal resistors, DC current/voltage inputs, etc. These input signals can be selected through parameter settings. ADS-DM201A is a model fixed as a potentiometer input. The standard configuration of this module includes power supply and communication functions. The input, communication, output, power supply, and module power supply are isolated from each other. The power supply range is 10VDC to 30VDC, and the power consumption is less than 4.8W. Basic Specifications Power supply voltage: 10~30VDC Power consumption: less than 4.8W Environmental temperature: -10~55 ℃ (storage: -25~65 ℃) Environmental humidity: 35~85% RH, no condensation Absolute humidity: MAX. W. C 29.3 g/m3 dry air at 101.3kPa Installation location: indoor, height<2000m Insulation resistance: ≥ 100M Ω (500V DC MEGA reference) Insulation strength: 1000V AC (test conditions: 50/60Hz, 1 minute) Anti interference: IEC61000-4-2 (electrostatic discharge), Class III IEC61000-4-4 (Electrical Fast Transient Pulse Group), Class III IEC61000-4-5 (surge), Class III Input specifications Input: Thermocouple, thermal resistor, DC current/voltage input, input signal set by parameters. Please refer to [Input Signal] for details. Isolation: Isolation between input and communication, output, feeding, and module power supply. Conversion cycle: 0.1 seconds (thermocouple input is 0.2 seconds) Basic error: ± 0.2% F • S When the input signal is selected as a B-type thermocouple, accuracy is not guaranteed when it is less than 250 ℃. Cold junction compensation accuracy: it is related to the cold junction compensation mode, the Thermal equilibrium at the terminal and the cold junction compensation coefficient. Feed specifications Feed: 24V ± 5% below 50mA Isolation of feed and input, output, communication, and module power supply Communication specifications Communication interface: RS485 Isolation: isolated from input, output, feed, and module power supply Communication protocol: Modbus RTU protocol (slave mode)/TC-ASCII protocol can be set Module address: 1-99 optional Baud: 2400 ／ 4800 ／ 9600 ／ 19200 ／ 38400 bps ／ 57600 bps ／ 115200 bps settable Response time: 500 μ S (measured value) Data format: 1-bit start bit, 8-bit data bit, 1-bit Parity bit, 1-bit or 2-bit stop bit optional Parity check: optional Check digit (odd check/even check/no check) Synchronization method: Start stop synchronization method Transmission mode: bidirectional half duplex multipoint connection Communication distance: ≤ 1.2km, requiring the use of compliant cables and matching resistors, preferably twisted pair cables Code Description | content | | | Code Description | | ADS-DM201- | | | Single channel analog universal input module with 0.2 level accuracy; Measurement and control speed 10 times per second | | ADS-DM201A- | | | Single channel Potentiometer input module, 0.2 class precision; Measurement and control speed 10 times per second | | Output (option) (maximum resolution: 1/10000; current output load ≤ 600 Ω, voltage output load ≥ 100K Ω) | | A1 | Current output (4-20) mA, (0-20) mA, (0-10) mA | | A2 | Voltage output (0-5) V, (1-5) V | | A3 | Voltage output (0-10) V | | feed | | B1 | 24V ± 5% below 50mA (no feeding is required for Potentiometer input) | | communication | | MS2 | The RS485 interface can select TC-ASCII or Modbus-RTU protocols through parameter settings | | Power specifications | | V1 | 10-24V AC 50/60 Hz; 10-30V DC |
