Introduction
1.0 Introduction
The Power & Communications Module (PCM) contains the high
voltage power supply, digital and analog communicated interfaces for
Tintometer Process Sensors. It provides 24VDC, as well as
connections for two (2) 0-20 / 4-20mA analog current outputs, three
(3) digital relay outputs, and one (1) optional RS-485 MODBUS
network.
A qualified electrician trained in the installation of electrical
equipment should read and understand this manual prior to working
with this component as potential lethal hazards are present.
The manufacture does not take responsibility for any issues caused by
use of the unit not in accordance with the instructions laid out in this
manual.
Preface
Do not exceed temperatures or time spans in any case.
All warning labels must NOT be removed and should be replaced if
they become damaged or faded.
Important Information
The PCM can be mounted to a panel or to a wall.
Notes on power connection
The PCM should be permanently connected to mains power.
See local building codes for permanently connecting equipment.
Safety instructions for operation
Never open the high voltage housing while the PCM is connected to
mains power. There is a danger of electric shock and other hazards.
The high voltage area may only be opened and serviced by qualified
professionals.
Ensure proper grounding of the metal bonding plate near the bottom
of the enclosure. It must be connected to GND for proper operation.
Cleaning
Use a damp cloth with a non flammable, non corrosive detergent.

3. Remove the appropriate hole plugs from the bonding plate. The two
near the back are intended for high voltage use.
4. Connect AC power to the connector labeled J1 (see Figure 5 for
power connector location). AC power and protective earth wires
must be 12 to 18 AWG. A local disconnect switch or circuit breaker
which meets local electrical code is also required on the AC power
input, and must be located near the PCM.
5. Connect Relay outputs to connectors labeled J2, J3, and J4. Note that
Normally Open (NO) and Normally Closed (NC) contacts are provided/
See Figure 6 for wiring information.
6. Reinstall the low voltage board, connectors at position J3 and J9, and
the red thumb screw
