的详细介绍
Pepperl+Fuchs HiC2871A Intrinsically Safe Solenoid Driver
(Part No.: HiC2871A)
The Pepperl+Fuchs HiC2871A is a specialized interface module designed to safely control solenoid-operated devices, such as valves and actuators, located within hazardous areas. It functions as a power amplifier and intrinsic safety (IS) barrier, allowing a low-power control signal from a safe-area system (like a PLC) to safely switch a higher-power load in a potentially explosive atmosphere.
Key Features
-
Intrinsic Safety Output: Provides an intrinsically safe (IS) output certified for hazardous areas (e.g., Zone 1/21). This allows the direct connection and safe operation of solenoid coils within explosive atmospheres without the risk of causing ignition.
-
High-Current Switching Capability: Acts as a power amplifier, switching the higher current required by a solenoid (e.g., several hundred mA to >1A) using a low-current control signal (typically a PLC's 24V DC digital output).
-
Short-Circuit and Overload Protection: The output is short-circuit proof and protected against overload, safeguarding both the driver module and the field wiring in case of a fault at the solenoid.
-
Status Feedback: Often includes a signal feedback channel that monitors the state of the IS output circuit. This feedback signal can be wired back to the control system (PLC input) to confirm that the commanded action (energize/de-energize) has been successfully executed in the field.
-
Compact DIN Rail Design: Built for easy installation on standard 35mm DIN rails within control cabinets, featuring screw terminals for reliable connections.
-
LED Diagnostics: Includes LED indicators to show the status of the control input, the output power stage, and any fault conditions, enabling quick visual diagnostics.
