Versatile Analog Output Control
The 45C381 output module provides four high-precision analog output channels for drive and actuator control applications. This output module offers field-configurable output signal types, allowing each channel to operate independently as either 4-20 mA current or 0-10 VDC voltage. The 12-bit resolution ensures smooth and precise control over connected devices.
The output module achieves an accuracy of ±0.1% of full scale at 25°C, delivering reliable performance for demanding process control loops. The temperature drift of only ±50 ppm/°C maintains this accuracy across varying ambient conditions. A fast 1 ms settling time enables rapid response in dynamic control applications, such as speed regulation and torque control.
Output Drive Capabilities and Protection
This output module drives current loops up to 600 Ω or voltage loads down to 2 kΩ, accommodating a wide range of field devices. The 45C381 includes built-in short-circuit protection, which limits the output current and prevents damage from accidental wiring faults. The module monitors output load conditions and reports any fault status to the main processor for safe system shutdown.
Each channel includes a dedicated green LED that illuminates when the output is active. This visual indication helps maintenance personnel quickly verify proper output operation without requiring external test equipment.
Physical Design and Installation Features
This output module occupies a single slot in the Automax or FlexPak 3000 rack and measures 45 mm in width. The module weighs 0.25 kg, making handling easy during installation and replacement. A 20-point removable screw terminal block on the front panel accepts all field wiring connections, simplifying both initial installation and ongoing maintenance.
The module requires an external 24 VDC supply for loop power when operating in current mode. The 45C381 draws only 200 mA from the 5 VDC backplane, minimizing additional load on the system power supply. The terminal block accepts wires up to 2.5 mm² (AWG 14), ensuring secure connections in industrial environments.
Power Consumption and Environmental Specifications
This output module operates reliably across a temperature range of 0°C to +55°C. The 45C381 also withstands humidity from 10% to 90% (non-condensing) and resists vibration up to 2G at 10-100 Hz, making it suitable for diverse factory floor conditions.
