Vibro-Meter VM600 IOC16T – 16‑channel I/O and Transient Data Interface for Machinery Protection
The Vibro-Meter VM600 IOC16T is the input/output and communications interface card for the VM600 rack, designed to bridge your protection/monitoring modules with the DCS, historians, and maintenance tools you rely on daily. From my experience, the “T” version is prized for its transient data capability—so you don’t just get alarms, you also get the high-resolution waveform data engineers typically want when diagnosing trips or near-misses. In many cases, the IOC16T is paired with high-density measurement modules to expose up to 16 channels of conditioned outputs from a single slot, which keeps panel space tight and wiring clean.

Key Features
- High‑density I/O (up to 16 channels) – Typically matches the channel count of the paired VM600 measurement module, minimizing rack slots per machine train.
- Transient data streaming – Captures waveform and spectral data for diagnostics, not just steady-state values, which seems to be what most reliability teams ask for after a trip.
- Buffered dynamic outputs – Safe, conditioned access to raw vibration signals for portable analyzers or permanent data collectors.
- 4–20 mA proportional outputs – Easy tie-in to DCS/PLC for trending overall values without adding extra converters.
- Alarm relays – Configurable relay contacts for OK, Alert, and Danger status; supports standard protection voting practices in many cases.
- Industrial communications – Ethernet for configuration and data; typically supports Modbus TCP and, where fitted, serial Modbus for legacy systems.
- Plug‑in VM600 rack module – Front-insert, single-slot card for fast swap-out; wiring stays on the rack terminal base.
- VibroSight integration – Configuration, archiving, and analysis via Vibro-Meter software toolchain.
Typical Use Cases
– Gas and steam turbines: protection outputs to DCS while streaming transient data to engineering workstations for root-cause analysis.
– Compressors and expanders: dense 16‑channel layouts keep multi-bearing trains in a single rack bay.
– Balance-of-plant rotating assets: easy 4–20 mA handoff to PLCs with buffered outputs available for spot checks.

Related / Supporting Products
- VM600 MPC4 – 4‑channel machinery protection card; often paired with IOC modules for relay logic and 4–20 mA outputs.
- VM600 XMV16 – 16‑channel dynamic measurement card; the IOC16T complements it with high‑density outputs and transient streaming.
- VM600 CPUM – Rack controller/CPU for data handling and system supervision.
- VM600 RLC16 – Relay output module where larger external relay counts are needed.
- VM600 IOC4T – Lower channel‑count alternative to IOC16T, for smaller machines or when rack space is not constrained.
A customer in a combined‑cycle plant recently standardized on IOC16T with XMV16 so each gas turbine train fit neatly in one rack bay—4–20 mA to the DCS, buffered outputs for their portable collector, and transient data to VibroSight without extra hardware. You might notice that maintenance windows get shorter when card swaps don’t disturb field wiring; that was their experience too.
Installation & Maintenance
- Cabinet & rack: Install in a 19‑inch cabinet with adequate ventilation; follow VM600 rack grounding and bonding practices.
- Wiring: Use shielded twisted pairs for dynamic signals; route separately from power to reduce noise. Keep 4–20 mA loops isolated as per site standards.
- Power: Provide clean 24 VDC to the VM600 rack with recommended redundancy (A/B feeds).
- Safety: De‑energize relay loads before maintenance; verify OK/Danger logic and trip voting after any configuration change.
- Routine maintenance: Periodically verify 4–20 mA scaling, exercise relays, and check buffered outputs with a handheld analyzer. Firmware and configuration backups via VibroSight are good practice after any change.
Quality & Certifications
- Conformity: CE (EMC and Low Voltage), RoHS compliant
- Agency: UL/cUL recognition for use in industrial control equipment (rack‑based)
- Manufacturer’s warranty: typically 12 months standard
If you need a quick compatibility check with your existing VM600 rack build or want help mapping the 4–20 mA ranges to your DCS tags, share the rack card list and we’ll size the IOC16T correctly. From my experience, getting the channel mapping right at the start saves a lot of rework when commissioning.
