Order now the 2085-IQ32T, a maximum-density 32-channel digital input module engineered for large-scale automation projects.
What Is the 2085-IQ32T?
The 2085-IQ32T is a high-density 32-point digital input module that doubles the input capacity of a standard expansion slot for Allen-Bradley Micro850 and Micro870 controllers. Utilizing a high-density 40-pin connector instead of traditional screw terminals, this module is designed for applications where cabinet space is at a premium and a high volume of digital feedback is required. It operates at 24V DC and supports both sink and source inputs, making it one of the most efficient I/O solutions in the Micro800 ecosystem.
Key Technical Specifications
- Inputs: 32 Sink/Source (Type 3)
- Connection Type: 40-pin Header (requires 2085-CBL32 cable)
- Input Voltage: 24V DC nominal
- Isolation: 50V (continuous) Basic Insulation Type
- Backplane Current: 190mA @ 5V DC
- Input Impedance: 3.9 kΩ
Architecture and Cable Management
Unlike lower-density modules, the 2085-IQ32T uses a specialized header system to manage the 32 input signals. This requires the use of pre-wired cables (like the 2085-CBL32) or a transition module to breakout the signals to terminals. This architecture significantly reduces wiring errors and decreases the time required for panel assembly. It is particularly effective in high-I/O applications such as packaging lines or complex material handling systems where dozens of proximity sensors must be monitored.
Expert Tips
Because the 2085-IQ32T concentrates 32 signals into a small area, heat dissipation is more critical than with 16-point modules. Ensure the PLC rack is mounted horizontally to take advantage of natural convection cooling. Additionally, always use the dedicated Rockwell 40-pin cables to ensure proper pin-to-channel mapping; third-party cables often lack the necessary shielding and wire gauge to maintain signal integrity over long distances.
Frequently Asked Questions
Q: Does the 2085-IQ32T come with the terminal block included?
A: No, this high-density module uses a 40-pin connector. You must purchase the 2085-CBL32 or a similar 40-pin cable separately for installation.
Q: What is the maximum voltage this module can handle?
A: While rated for 24V DC, the module can handle an absolute maximum of 30V DC. Exceeding this will damage the internal optocouplers.
