HollySys LK411 8-Channel Current Analog Input Module

Product Overview

HollySys LK411 is an eight-channel current-type analog input module for LK-series programmable controller systems. It accepts 0–20 mA or 4–20 mA field signals and converts them with 16-bit resolution.

The module supports field calibration, limit and over-range alarms, open-circuit detection and hot swapping. It can be installed on an LK local backplane or expansion backplane.

Specifications

Features

• Eight independent current-input channels.
• Selectable 0–20 mA and 4–20 mA measurement ranges.
• 16-bit conversion for process-signal acquisition.
• Built-in field calibration and diagnostic alarms.
• Line-break detection for current loops.
• Hot-swappable LK-series module design.

Applications

Suitable for collecting current outputs from transmitters and signal conditioners in machinery, utility and process-control systems based on the HollySys LK platform.

• Pressure, temperature and flow transmitters
• Machine and process analog measurement
• LK-series PLC expansion and maintenance

Lifecycle

Confirm the LK411 model code, current range, backplane position and 24 VDC supply before replacement. The module is a current-input device; it should not be substituted for voltage-input or analog-output models without an engineering review.
