System compatibility120-166-006 belongs to MODICON Micro series expansion I/O module. Compatible with MODICON Micro series CPU and power supply modules. It can be cascaded with other Micro digital or analog expansion modules. Suitable for packaging machinery,small production line,standalone machine control system upgrade and replacement as industrial spare part.
Function120-166-006 is 16-point 24VDC digital input expansion module. It collects on/off signals from proximity sensors,limit switches and push buttons,converts field DC signals into internal logic data and transmits to PLC CPU. Each channel has independent status LED, equipped with surge suppression protection. Widely used for expanding discrete signal acquisition points of small PLC, serving as reliable PLC I/O spare part.
InstallationCut off power before installation. Mount the 120-166-006 module on DIN rail inside electrical cabinet. Connect expansion bus cable between CPU and this module. Wire field 24V DC input signals to terminal block. Complete channel signal test via ProWORX programming software before formal operation.
InterfaceExpansion bus connector,field signal terminal block,channel status LED indicators for 120-166-006 MODICON digital input module.
FeatureMODICON 120-166-006 Micro series 16-channel DC input expansion module,two groups of 8 isolated channels,surge suppression protection,LED per channel indication,compact DIN rail design,convenient cascading installation,IP20 cabinet protection. This discontinued legacy industrial spare part used for old Micro PLC system I/O expansion maintenance and replacement.
DiagnosticModule not detected: check expansion bus cable,bus connection and module insertion for 120-166-006. No channel signal reading: inspect field 24VDC power,switch contact and terminal wiring. Signal random jump: check cable shielding and grounding,eliminate electromagnetic interference. LED no light: verify channel wiring and module hardware damage. I/O reading fault: read I/O diagnostic information through ProWORX software.
Product Brief120-166-006 is MODICON Micro series 16-point 24VDC digital input expansion module. It extends the discrete input quantity of Micro PLC, collects field switch signals, classic spare part for legacy small automation equipment renovation.
