Model Explanation

TC = C Series Card; PRS = Processor Series Control Processor; 021 = Hardware Version, Spare Part Code 51404305-225. Technical Specifications

Backplane power supply: 5V/3.3V/24VDC. The overall power consumption is approximately 7W. Memory: 128MB high-speed ECC-RAM + 256MB FLASH firmware storage.

Logical scanning cycle minimum 1ms, deterministic control operation. Operating temperature: 0℃~+60℃. Humidity: 5%~95% without condensation. Net weight: 544g. CE and UL industrial certifications.

Interface and communication configuration

Panel: Running, Fault, Redundancy, Network status LED indicators;

Backplane gold finger plug into the IOTA base, local bus connects to the rack I/O card;

The base comes with ControlNet + Ethernet communication interfaces, respectively connecting to remote I/O and upper server; When redundant configuration is adopted, it cooperates with TC-PRR021 to achieve master-slave synchronization.

Core functions

Full device control loop operation, logic interlock, sequential control program execution; Manage local + remote CIOM rack I/O data; Real-time redundant status data mirroring, fault non-disruptive switching; Firmware online upgrade, hardware self-diagnosis alarm; Automatic synchronization of engineering configuration after hot-swappable replacement while powered on. Applicable scenarios

Petrochemical refining and chemical DCS main control cabinet, power plant boiler / turbine control system, continuous process control of chemical plants, highly reliable redundant control system for fine chemicals.

Operation and maintenance instructions

The redundant main control must be equipped with TC-PRR021 redundant synchronization module; the cabinet environment should be dust-proof and temperature-controlled to avoid high temperatures; program loading is done through Control Builder software; annual inspection: ensure the firm connection of the base wiring and communication connectors.
