The PMM-305P (Rhino series) from MC-monitoring SA is a 5-channel distributed process monitoring module that bridges third-party vibration and condition sensors to DCS, PLC, and SCADA systems. It communicates via Modbus RTU, Modbus TCP, and OPC UA, with a built-in firewall for network security.

What sensor types does it support?

Four factory pre-configured conditioning modes cover common industrial sensor types:

• 4× differential voltage inputs
• 4× IEPE accelerometer inputs
• 4× differential 0–20 mA current loop inputs
• 2× differential voltage + 2× IEPE (mixed mode)

How many channels and modules can I deploy?

Each PMM-305P provides 5 channels — 4 dynamic signal inputs plus 1 reference (tachometer/speed) channel. Up to 8 modules can be stacked, delivering 32 dynamic monitoring channels from a single communication interface.

How does it handle alarms?

Each dynamic channel supports individually configurable alarm and danger thresholds. When a threshold is breached, the module asserts a digital output (DO) signal that can drive an external annunciator, stack light, or interlock relay.

How does it differ from the PMM-300P?

The PMM-305P is designed for system integration and data routing — collecting signals from third-party devices and forwarding them to higher-level systems. The PMM-300P is oriented toward direct machine protection with voting logic and shutdown relays. Choose the 305P when you need to integrate mixed sensor types into a unified monitoring network; choose the 300P when the primary requirement is trip-level machine safeguarding.

What software does it work with?

It bridges to MC-monitoring's CMS-500 PLUS Orca software for analytics, trending, and predictive maintenance. Typical applications include gas and steam turbines, hydrogenerators, wind turbines, pumps, fans, cooling towers, and gearless mill drives.
