Key Functional Characteristics
Universal Signal Processing: The CI521-MODTCP is designed with versatile input hardware that accepts Voltage (U), Current (I), and RTD sensors. This flexibility allows the module to interface directly with diverse instruments such as pressure transmitters and temperature probes, eliminating the need for signal converters and reducing cabinet complexity.
Integrated Actuator Control: Beyond data collection, the module provides specialized outputs for driving process equipment. With its dual analog outputs supporting both Voltage and Current modes, it can precisely manage the speed of variable frequency drives or the position of control valves, streamlining the local automation loop.
High Density Digital Logic: The hardware includes 16 digital points for standard switching tasks. The transistor based outputs are capable of managing 0.5A loads, while the inputs feature an adjustable filter to ensure signal accuracy in environments with high electromagnetic interference. This combination provides a robust interface for proximity sensors, limit switches, and solenoid actuators.
