1762-IQ16 16-Channel Discrete Input Module
Product Introduction
The Allen-Bradley 1762-IQ16 adds sixteen discrete input points to your MicroLogix system. This module accepts 24V DC signals from various field devices. It supports both sinking and sourcing wiring configurations for maximum flexibility.
This input module works seamlessly with MicroLogix 1100, 1200, and 1400 controllers. It connects via a simple ribbon cable to the controller bus. Moreover, the 1762-IQ16 features fast signal response times. It delivers an 8.0 ms delay for both ON and OFF transitions.
Furthermore, this module offers two mounting options. You can install it on a standard DIN rail or directly on a panel. Its compact size helps optimize control cabinet space.
Technical Specifications
The 1762-IQ16 provides reliable discrete input performance. It features sixteen channels that accept 10 to 30V DC signals. Each channel is independently configurable for sinking or sourcing operation.
Here are the key electrical specifications:
Nominal Input Voltage: 24V DC
Operating Voltage Range: 10 to 30V DC
On-State Voltage (min): 10V DC
Off-State Voltage (max): 5V DC
On-State Current: 2.0 mA min to 12.0 mA max
Off-State Current (max): 1.5 mA
Additionally, this module provides a heat dissipation of 3.7 Watts maximum. Its IP20 enclosure rating offers basic protection. The 1762-IQ16 also includes a single status LED for power indication and troubleshooting.
Compatibility and System Expansion
This discrete module integrates easily with several MicroLogix platforms. For instance, the MicroLogix 1100 supports up to 4 expansion modules. Meanwhile, the MicroLogix 1200 accommodates up to 6 modules. The MicroLogix 1400 can handle up to 7 expansion modules.
You can mix the 1762-IQ16 with other MicroLogix I/O modules. This flexibility allows you to build custom systems. For example, you can combine analog and discrete modules as needed.
Wiring and Configuration Guide
The 1762-IQ16 supports both sinking and sourcing field devices. Sinking devices connect to the negative side of the module. Sourcing devices connect to the positive side. Source devices provide current to sink devices.
For wiring, the module includes a finger-safe cover. This protects users during installation. The input terminals use bit positions 0 to 15 of word 0.
Configure each channel after installation. Use the controller's programming software for setup. The 1762-IQ16 works well with limit switches, proximity sensors, and relay contacts.
Installation and Mounting Options
Mount the 1762-IQ16 using either DIN rail or panel mounting. Its dimensions are 90mm (H) x 87mm (D) x 40mm (W). Including mounting tabs, the height is 110mm.
Connect this module to the controller using the provided ribbon cable. This cable establishes both communication and power distribution. It connects via pin contacts on the front panel.
For optimal performance, install the 1762-IQ16 in clean, dry environments. Avoid locations with excessive vibration or moisture. Also, ensure circuits do not exceed Overvoltage Category II standards.
Data Representation and Processing
The 1762-IQ16 stores input data in the module's data file. This information can be represented in various radix formats. Specifically, you can view data as binary, octal, decimal, or hexadecimal values.
This flexibility helps with programming and troubleshooting. For instance, binary representation shows individual bit status clearly. Decimal format is useful for process monitoring.
