MeloAuto-Trusted PLC & DCS Parts Supplier
Function:
The Digital Output Bussed 24VDC (DO24V) module is designed to reliably control 24V digital output signals, enabling the operation of various process equipment such as solenoid valves and interposing relays. The module’s versatility makes it suitable for use in a wide range of control applications.
Notable Features:
- Extensive Internal Diagnostics:
Provides comprehensive diagnostics to ensure data integrity, identifying potential issues before they affect system performance. - Optional Redundancy:
Redundancy can be added to ensure uninterrupted operation even if one output channel fails, providing an additional layer of reliability. - Electronic Overcurrent Protection:
Built-in protection against overcurrent conditions helps prevent damage to the module and the connected devices. - Configurable Safe-State (FAILOPT):
The FAILOPT feature allows for per-channel configuration to either hold the last value or shed to a safe value in case of a fault. This provides the user with control over system behavior during failure scenarios. - Flexible Output Types:
Outputs can be configured as latched, pulsed, or pulse-width modulated (PWM) per channel, offering the flexibility to meet specific control needs.
Bussed 24VDC Output:
The Digital Output Bussed 24VDC module allows for both internal and external field power excitation. As a bussed output device, all outputs share a common return (ground). The module draws power from either the system power supply or an externally connected 24V power supply. When an external source is used, outputs can be galvanically isolated from the Series C power system. A wiring option on the IOTA (Input/Output Terminal Adapter) determines whether the outputs reference the Series C system power or an external field power source.
FAILOPT Functionality:
- HOLD THE LAST VALUE:
If the system detects an issue, the output can maintain the last valid value. - SHED TO A SAFE VALUE:
Alternatively, the output can be configured to shed to a predefined safe value, offering flexibility in how faults are handled.
