Storage requirements: The module should be stored in an ESD bag or according to the manufacturer’s storage requirements. The temperature and humidity of the module storage room should also meet the requirements of the manufacturer. When accessing the module, take anti-static measures, do not touch the circuit board with your hands, and register it, and go through the procedures for entering and leaving the warehouse.
Control Power: Range from 50-300 VDC and 60-264 VAC.
Measurement Quantities: Includes phase current, current demand in amperes, motor load in x fLA, percentage of unbalanced current, ground fault current in amperes, input switch status (open or closed), relay output status (energized or de-energized), RTD temperatures, rotational frequency in Hz, phase and line voltages, frequency in Hz, power factor leading/lagging, active power and active power demand in watts, reactive power and reactive power demand in vars, apparent power and apparent power demand in VA, actual power consumption in MWh, and reactive power consumption/generation in Mvarh12.
Communication Ports: RS232 port on the front of the relay and RS485 port on the rear34.
Environmental Parameters: Operating range from -40°C to +60°C, storage range from -40°C to +80°C. Maximum ambient humidity up to 95% non-condensing3.
Product characteristics: Industrial control products that may be key components used in industrial automation systems.
Operating voltage: A variety of voltage specifications may be supported, but the specific value is not clearly given.
Output frequency: 50kHz (This information is derived from the parameters of similar products, but not necessarily the exact parameters of the ABB DSTC456).
Product certification: PLC module and DCS module (indicating its possible use in programmable logic controllers and distributed control systems).
