1.Main Functions

It is a VMEbus slave‑interface carrier board, provides four MODULbus mezzanine sockets for plug‑in small‑form I/O sub‑modules (analog input/output, digital I/O, motion modules etc.), only occupies one single VME chassis slot.
Implements A24/D16 VMEbus communication interface; supports 2K‑byte Short‑I/O or standard memory address mapping for host CPU access. Each MODULbus socket owns independent 512‑byte address space.
Supports vector‑based interrupt generation from each sub‑module; interrupt level and interrupt vector are user‑configurable via hardware jumper settings, delivering hardware event signals to VME system host controller.
I/O signals can be routed via front‑panel connectors or VME P2 backplane connector for flexible cabinet wiring layout.
Optional onboard DC/DC converter variant (VMOD‑IO/E) supplies ±15V auxiliary power for analog MODULbus sub‑modules.
Passive carrier hardware without local processor; all computation is executed by upper VME main CPU board. Operating temperature range: 0 ℃ ~ +70 ℃ for cabinet‑mount deployment.
Converts VME‑bus commands and data into MODULbus signals, realizes transparent data transmission between VME host and various plug‑in I/O mezzanine modules.

Janz VMOD‑IO Control Board

Janz VMOD‑IO Control Board

Widely used in legacy VME‑bus industrial control systems for machine‑tools, precision grinding equipment, test‑bench automation and special‑purpose industrial controllers.
System integrators configure mixed‑signal I/O by inserting different MODULbus sub‑modules (digital‑IO, AI/AO, encoder‑interface, motion‑control sub‑modules) onto VMOD‑IO, achieving flexible I/O expansion within limited VME chassis slots.plcva.com
Deployed in industrial cabinet for field sensor signal acquisition, actuator output driving and motion‑control signal interaction.
Belongs to obsolete original OEM hardware; mainly used as maintenance spare‑part for existing running VME‑based automation equipment, not recommended for new‑project design.
Cannot operate independently. Must be installed in standard 6U VME chassis, cooperate with VME host CPU board and matched MODULbus mezzanine modules to realize complete I/O functions.
