overview：
Woodward 9905-972 Linknet 6-channel output module is a key device in the field of industrial control. It consists of four modules, each module accepts six contact inputs, and the contact wetting voltage is 24Vdc, which can be powered by the control unit or an external power supply of 18-32Vdc, 100-150Vdc. This voltage can be obtained from an external power supply of 18-32Vdc or 100-150Vdc.The following is a detailed description of the module's features and specifications.
Fuctions & Features:
- Channels and Power: The Woodward 9905-972 Linknet 6-channel Output Module controls four modules, each of which accepts six contact inputs. The contact wetting voltage can be provided by the control unit or an external power supply, and each relay module has a contact wetting voltage of 24Vdc. To obtain this voltage, an external 18 - 32Vdc power supply or a 100 - 150Vdc power supply can be selected.
- Latent Fault Detection Mechanism: In a fault-tolerant system, the Woodward 9905-972 Linknet 6-channel Output Module plays a key latent fault detection role. Through the specially configured discrete output function, relay faults can be accurately detected.
