Connects, controls and reports.
One box on site that reads your PLCs, meters and sensors, runs its own control logic, and sends the data to the cloud for live pages, reports and alarms.
A PLC built in
Control logic and inputs and outputs on the box, so control runs on site.
Works with what you have
Reads your existing PLCs and meters. Nothing to replace.
Online any way it can
Ethernet, Wi-Fi or mobile data.
Your machines on one side. The internet on the other.
- PLCsReads the PLCs you already have
- Modbus TCPMeters, drives and controllers on Ethernet
- Modbus RTUOlder equipment on a serial line
- Wired inputs2 digital (DI) and 2 analogue (AI) inputs
- Relay outputs2 relays (DO) to switch pumps, valves and alarms
- EthernetThe site network
- Wi-FiJoins Wi-Fi, or links buildings over Wi-Fi
- Mobile data4G where there is no network
Solid lines are wired. Dashed lines are wireless.
Fit it on site
Next to your panel, on the machine network. Our team fits it and wires it in.
Switch on what you need
Modbus, PLC, mobile data, remote access. Each job is switched on separately.
It runs
Control runs on site and the readings go to the cloud.
One box, several jobs.
Most sites use a few of these. Each one is switched on or off on its own, and switching one off keeps its settings.
Controls on site
- A PLC is built in. Control logic runs on the box itself.
- Its own inputs and outputs switch pumps, valves and alarms.
- Control keeps running when the internet is down.
- Works next to your existing PLC, and only reads from it.
Talks to your machines
- Reads PLCs on the machine network.
- Modbus TCP over Ethernet.
- Modbus RTU over a serial line.
- Finds devices on the network by itself.
Gets online any way it can
- Ethernet or Wi-Fi on the site network.
- Mobile data (4G) where there is no network.
- Wi-Fi links between buildings.
Sends data to the cloud
- Every reading goes to the Prometrics cloud.
- Live pages and alarms in Prometrics OI.
- Trends and reports in Prometrics Insight.
- Outgoing connections only. Nothing is opened on your firewall.
Lets engineers in
- Remote access through Prometrics Connect.
- Engineers use their own PLC software, as if on site.
Set up on its own screens
- Status, inputs and outputs, signals and network on one set of screens.
- Switch each job on or off. Switching off keeps its settings.
- A log of what the box has done.
You need an Edge on site for these.
- Model
- PM50, compact, with mounting ears for a panel or wall
- Control
- Built-in PLC logic controls the equipment wired to its own inputs and outputs; PLCs and meters it connects to are only read
- Inputs and outputs
- 2 digital inputs (dry or wet contact), 2 analogue inputs (4–20 mA or voltage, 12-bit), 2 relay outputs (3 A, 250 V AC)
- Power
- 8–28 V DC, or 5 V over USB-C; about 0.5 W in normal use, 1.6 W at most
- Serial port
- RS485 or RS232, chosen when ordering
- Storage
- Built-in memory, plus a TF (microSD) card slot for local logging
- Machine connections
- PLCs on the machine network; Modbus TCP over Ethernet; Modbus RTU over serial
- Device discovery
- Scans the network and lists the devices it finds
- Internet connection
- Ethernet (10/100), Wi-Fi (2.4 GHz) or mobile data (4G)
- Wireless
- Wi-Fi links between buildings, Bluetooth 5
- Cloud
- Readings sent to the Prometrics cloud over an encrypted connection; outgoing connections only, so no ports need to be opened
- Remote access
- Through Prometrics Connect, over a secure VPN
- Operating conditions
- −40 °C to 85 °C; 5–95 % humidity, non-condensing
