Honeywell 8C-TDOD51 51306975-175 Digital Output Module

The  8C-TDOD51 Digital Output Bussed 24VDC (DO24V) module is designed to switch reliable 24V digital output signals for controlling various process equipment, including solenoid valves and interposing relays.

Notable Features

• Extensive internal diagnostics to ensure data integrity.
• Optional redundancy for increased reliability.
• Safe-state (FAILOPT) behaviors for secure operations.
• Supports latched, pulsed, or pulse-width modulated output (per channel).
• Galvanic isolation (System to Field) with external user-supplied power.
