16/32-Channel Digital Input Modules
Input modules collect contacts and equipment states; they do not drive loads. Select by input count and cabinet layout, and add an output controller when equipment switching is required.

Product overview
The light displays states determined by a PLC, controller or supervisory application. Consistent color meanings help operators recognize equipment conditions.
Functions and integration
Control options
Digital-signal versions provide direct triggering; RS485 versions receive bus commands using their respective electrical interfaces.
RS485 operation
Modbus RTU controls individual colors, combinations and flashing.
State mapping
Assign consistent meanings to idle, running, alarm and completed states.
Applications and operating workflow
Equipment
Display operating and fault decisions made by the control system.
Process monitoring
Indicate conditions, timing and completion in material-treatment workflows.

Selection and system combinations
The light converts equipment or system states into local colour and alarm indications. Input modules, controllers or host systems perform status acquisition, condition evaluation and load control.
ZMRN1016S3-V5 Eight-Channel Ethernet IO Controller
Select by channels and operating modes when Ethernet control and input status are required together. Compare dedicated input modules for many contacts and Q-series controllers for other output scales.

01
Turn system states into visible field indications
Map red, yellow and green to operating, waiting, warning or completion states, with flashing and color combinations for additional distinctions. Align the meaning with the HMI, platform and equipment labels for operators and maintenance teams. The lamp displays the result while a PLC or controller evaluates the conditions, which can originate from environment, level, equipment or power monitoring.
02
Choose digital control or RS485 by the state source
Use a compatible digital-control version when an existing PLC or relay already supplies state signals. Choose the RS485 Modbus RTU version for bus-controlled projects or a larger state model. Addressed commands select colors, combinations and flashing, linking the source state to the local indication. Each version uses its corresponding supply and signal wiring.
03
Select the enclosure for the mounting and viewing position
The small form suits compact workstations and equipment panels; the large form suits equipment tops or more open areas. Consider mounting height, viewing direction, ambient light and obstructions as well as dimensions. A consistent color map and zone identification across machines helps teams relate local indications to platform events, work orders and operating records.
Selection questions
How can states be distinguished beyond a single steady color?
The RS485 version supports commanded color combinations and flashing. Define patterns for waiting, maintenance, abnormal and complete states and keep them aligned with the supervisory system.
How can color meanings remain consistent across equipment?
Define a project state table, such as running, waiting, abnormal and complete, and use the same meanings on equipment labels, platform events and lamp indications.
Frequently asked questions
Does the light judge process quality?
No. The controller or supervisory logic determines the state.
Do all versions share wiring?
No. Digital-signal and RS485 versions use their respective interfaces.
