The 1X00781H01L is a power module for Emerson Ovation systems and is part of the Ovation Distributed Control System (DCS). Ovation system is one of Emerson process control systems, mainly used in power plant thermal automation control.
The power amplifier components of the output module of the power module include high-power transistor and field effect tube driving DC load, bidirectional thyristor driving AC load, and small relay driving both AC load and DC load. The typical value of the output current is 0.3 to 2A, and the load power is provided by the external field.
In the Ovation system, the internal circuit of the 1X00781H01L power module energizes the coil of the relay, and the normally open contact is closed to enable the external load to work. The relay acts as both isolation and power amplification, and provides the user with only a pair of normally open contacts for each route. In addition, the RC circuit in parallel with the contact and the varistor are used to eliminate the arc generated when the contact is broken to reduce its interference with the CPU.
In general, the 1X00781H01L power module, as part of the Ovation system, is mainly used to supply power to the system, and has a variety of power amplification components and contacts, which can achieve isolation and power amplification, and can eliminate the arc generated when the contact is disconnected to reduce the interference to the CPU.
