PM180
6-Channel Modbus Pyrometer Hub
Operator’s Guide
The PM180 is a temperature indicator, data logger, alarm unit and configuration tool for Calex
infrared temperature sensors. It is compatible with all models in the PyroBus and PyroMiniBus
series, as well as all PyroMini and FibreMini models with Modbus output.
The PM180 functions as the Modbus Master on an RS485 network of up to 6 temperature sensors,
and can itself be connected as a slave device to another RS485 network via a second, isolated
Modbus interface. This allows multiple PM180 units to be multi-dropped to create a large network
of sensors and displays.
Optional alarm relay modules allow the PM180 to be connected to alarm equipment such as
sounders and beacons, and optional analogue output modules allow it to be connected to nonModbus instrumentation.
All the configurable parameters for the hub, the connected sensors and the optional output
modules are adjustable via the PM180’s built-in resistive touch screen interface, which can be
operated even with gloves on.
With an optional MicroSD Card inserted, the PM180 functions as a fully-configurable data logger.

DATA LOGGING
With an optional MicroSD Card installed in the slot inside the PM180, data logging may be
manually started and stopped via a button on the temperature display screen, or scheduled to
begin at a pre-determined time via the Settings menu.
If the PM180 is connected via the slave interface to another Modbus network, logging may also be
started remotely by the Modbus Master on that network.

The PM180 has removable screw terminal blocks for the Modbus Slave and Modbus Master
interfaces.
− Connect the Master interface to the sensors and output modules. Be sure to check the power
supply requirements of each device before applying power.
− Optionally, connect the Slave interface to another Modbus network with its own Modbus
Master such as a PLC or SCADA system.
Isolation is provided between the Slave and Master interfaces.
MICROSD CARD AND BATTERY
The MicroSD Card and battery slots are located on the touch screen circuit board. Unscrew the lid
of the PM180 to access them.
The battery is optional. With a battery fitted, the internal clock will continue to run when the power
is off. Without a battery, the unit will request the date and time each time the power is cycled.
All other settings are stored in the unit’s permanent memory and will be preserved when it is
switched off, regardless of whether a battery is fitted.
