The Honeywell MC-TDOY22 is a digital output module designed for robust industrial automation control. This module provides 32 discrete output channels, each delivering 24VDC for consistent device operation. It specifically pairs with the MU-PDOY22 processor module to create a complete control solution.

Furthermore, the module integrates advanced Field Termination Assembly (FTA) technology. This design significantly streamlines wiring and maintenance processes in control panels.

Key Technical Specifications and Design

The MC-TDOY22 excels in precise switching and system protection. Each channel uses open-collector NPN transistors for reliable current-sinking operation. Consequently, the module ensures stable performance under demanding industrial conditions.

Here are the essential technical parameters for the module and its associated FTA:

Detailed Electrical Performance Ratings

Understanding the current ratings is crucial for proper system design. The Honeywell MC-TDOY22 module manages the following load currents per its FTA model, MU-TDOY22:

• Maximum Current per Point: 0.5A

• Maximum Current per 2 Points: 1.0A

• Maximum Total Current for 32 Points: 5A

Additionally, the module’s switching performance guarantees rapid system response. The turn-on and turn-off time is a maximum of 200 milliseconds. Moreover, it offers robust protection with surge withstand capability meeting the ANSI/IEEE C37.90.1-1978 standard.

Protection and Safety Features

The module incorporates critical safety components to ensure longevity. The associated MU-TDOY22 FTA uses one fuse for every two output points. Specifically, it requires a 1.6A, 125V fast-acting fuse with dimensions of 5.5 x 17.2 mm.

Other key safety parameters include an off-state voltage maximum of 30V and a very low off-state leak current of 0.5 µA maximum. These features collectively enhance the reliability and safety of your control system.
