Allen-Bradley 2085-RTD4 Micro870 series Plug-in PLC

Allen-Bradley 2085-RTD4 is an analog input module in the Micro870 series, designed for connecting resistance temperature detectors (RTDs) for accurate temperature measurement. The following is a detailed introduction:

Basic Information

Product Type: An expansion I/O module belonging to the Micro870 series, used for temperature measurement applications.

Number of Channels: Provides 4 independent RTD input channels, and can connect multiple RTD sensors at the same time to achieve multi-point temperature monitoring.

Electrical Parameters

Power Supply: Get power from the I/O expansion bus of the Micro870 controller, the maximum bus current is 120mA at 5V DC, and 60mA at 24V DC.

Power Consumption: The total power consumption is 1.95W when running.

Features

Supported RTD types: Supports multiple RTD types, including PT100 (IEC 60751 Class B), PT1000, NI100 and NI120, etc. You can choose the appropriate RTD sensor according to the actual application requirements.

Measurement range: The temperature measurement range is wide. For example, for PT100, the measurement range is - 200°C to + 850°C, which can meet the temperature measurement needs in different industrial environments.

Accuracy: It has high measurement accuracy, with a typical accuracy of ±0.2°C (at 25°C), which can provide accurate temperature data.

Resolution: 14 bits (13 data bits and 1 sign bit), the data format is left-aligned, 16-bit complement, which can accurately reflect temperature changes.

Wire configuration: Supports 2-wire, 3-wire and 4-wire RTD configurations. You can choose the appropriate wiring method according to the actual installation conditions and measurement requirements to improve the accuracy and reliability of the measurement.

Terminal blocks: Each module contains two 12-pin removable terminal blocks (RTBs) for easy wiring and maintenance.

Status indication: There is a green health indicator and four red error indicators to indicate the working status and fault information of the module.

Physical characteristics

Dimensions: 44.5mm×90mm×87mm.

Weight: 220g.

Installation requirements

Installation method: It can be installed on a DIN rail or panel mounted.

Installation environment: Electrostatic discharge needs to be avoided, and sufficient space should be left around during installation to ensure good air circulation and prevent overheating.
