ExpertDAQ EX9017F RS485 8-Channel Analog Input Module

Overview

The ExpertDAQ EX9017F is an 8-channel analog input module with a 12-bit converter and an isolated RS485 interface, part of the ExpertDAQ EX-9000 series of industrial data acquisition modules. It measures analog signals from field transmitters and sensors — 4-20 mA process loops, voltage outputs, and low-level transducer signals — and makes the readings available to PLCs, SCADA systems, and industrial PCs over the Modbus-compatible ASCII protocol. With input ranges from +/-150 mV to +/-10 V plus a +/-20 mA current range, one module type covers most industrial analog signals.

Seven Star LLC supplies the ExpertDAQ EX9017F analog input module for automation and instrumentation projects across the Sultanate of Oman and the GCC. Water and wastewater, power, oil and gas, and general industry rely on analog telemetry for process values, and our team provides genuine ExpertDAQ hardware with regional delivery to Muscat, Sohar, Salalah, and beyond.

Operating Principle

Process instrumentation converts physical quantities — pressure, temperature, level, flow — into standard electrical signals, most commonly the 4-20 mA current loop. The EX9017F reads these signals: each of its 8 input channels is software-configured for the required range, and the module converts the analog value into a digital reading that the host controller requests over the RS485 bus.

The module supports voltage ranges from +/-150 mV (for low-level sensors such as load cells and thermocouple-like signals) through +/-500 mV, +/-1 V, +/-5 V, and +/-10 V, plus a +/-20 mA current range for standard process loops. The 12-bit converter gives fine resolution, and the total sampling rate of 60 Hz across the channels is sufficient for monitoring and control data acquisition in industrial plants.

Engineering Design of the ExpertDAQ EX9017F

The EX9017F is engineered for industrial reliability: its RS485 interface is galvanically isolated to break ground loops between field wiring and the control system, and the module is powered from a wide 10-30 V DC supply so it can share plant DC rails. Field wiring connects to a screw terminal block, and the module supports baud rates from 300 to 115200 bps for flexible network integration.

Communication uses the ASCII protocol native to the EX-9000 series, which is simple to implement in SCADA, PLC, and custom industrial PC applications. Addressing, baud rate, and input range configuration are made on the module, and multiple modules can be distributed along a single RS485 network to gather analog data from across the plant.

Key Features

The ExpertDAQ EX9017F is specified for analog data acquisition in industrial installations. Its defining characteristics are:

• 8 analog input channels with 12-bit conversion.
• Software-selectable ranges: +/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, and +/-20 mA.
• Galvanically isolated RS485 interface for reliable communication.
• Total sampling rate of 60 Hz across channels.
• Wide 10-30 V DC power supply range for plant DC rails.
• ASCII protocol with baud rates from 300 to 115200 bps.
• Screw terminal block field wiring for fast installation.
• Supplied by Seven Star LLC for automation projects across Oman and the GCC.

Industrial Applications

The EX9017F gathers analog process data at the field level: 4-20 mA loops from pressure, temperature, level, and flow transmitters; 0-10 V signals from variable speed drives and analyzers; and low-level signals from sensors. Typical installations include water treatment plant telemetry, power and desalination station monitoring, oil and gas wellhead and process instrumentation, and industrial machine monitoring.

Seven Star LLC supports automation engineers across the Sultanate of Oman and the GCC with the ExpertDAQ EX9017F and the complete EX-9000 series. We provide modules on request with network planning guidance, so that analog telemetry projects from Muscat to Salalah are built on documented components.

Technical Specifications

The following table summarises the key parameters of the ExpertDAQ EX9017F analog input module:

Additional Technical Data

Beyond the input ranges and sampling rate, the EX9017F carries a measurement accuracy of ±0.1%, with zero drift of ±0.5 µV/°C and span drift of ±25 ppm/°C, giving stable readings over the operating temperature range. The RS485 interface provides 3000 V of galvanic isolation between the field wiring and the host system, an important safeguard against ground-loop currents and transient damage in plants with long cable runs between remote I/O cabinets and the control room.

The module operates across -25°C to 75°C ambient and can be stored between -40°C and 85°C, so it tolerates both un-conditioned outdoor enclosures and hot equipment rooms typical of GCC industrial sites. It draws a maximum of 1.3 W, is housed in a compact 100 x 70 x 25 mm DIN-rail enclosure weighing about 110 g, and carries CE, FCC, WEEE, and RoHS marks. Seven Star LLC checks these environmental and compliance parameters against the installation site before confirming an order.

Signal Range Selection for the EX9017F

Select the input range on the EX9017F to match the field signal: use the +/-20 mA range for standard 4-20 mA process loops, the 0-10 V compatible ranges for transmitter and drive outputs, and the low-level +/-150 mV range for small transducer signals. The isolated RS485 interface and wide 10-30 V DC supply make the module straightforward to install in plant cabinets.Seven Star LLC supplies this item on request with the manufacturer documentation, and availability and lead time are confirmed at quotation.
