2. PCE-MCA 50 Hardware Parts & Accessories
2.1 Unpacking & Inspection
At the factory each new PCE-MCA 50 passes a careful inspection. It should
be free of scrapes and scratches and in proper operation order upon
receipt. The receiver should, however, inspect the unit for any damage that
may have occurred during transit. If there are signs of obvious mechanical
damage, package contents are incomplete, or the instrument does not
operate according to specifications, contact the purchasing sales office as
soon as possible. The standard accessories are as follows:
If you have to return the instrument to the factory for any reason, use the
original packing whenever possible. Include a detailed description of the
reason for the return.

2.2 Operational Sections and Connections
All sections and connections are presented in detail on the next pages.
Note:
Keep in mind that the next picture (as well as all pictures of PCE-MCA 50
in this manual) has an example configuration of modules. The configuration
of your PCE-MCA 50 may vary significantly from the one in the picture.

➢ EM (Electric Measurements and 24V Supply) Measure Terminals
Input Terminals for measuring voltage, current, supplying loop power,
and Frequency and pulse types refer specification sheet on page no.
79 Section 6.6 and page no. 82 Section 6.13, 6.14.
• Current Measurement
PCE-MCA 50 supports current measurement using either PCE-MCA
50 as the loop power supply while at the same time measuring the
current or simply measuring the current while an external power
supply is used.
The following picture displays the connection for Current
Measurement for different mode. And also different ways of providing
the supply power to the loop.
➢ mA Current Measurement
In this mode PCE-MCA 50 not providing any supply voltage.
For proper measurement the external device should capable of
providing the voltage supply. If the external device should not
capable, an external Power Supply should be connected in
series.

➢ mA Read Power Current Measurement
In this mode PCE-MCA 50 works as Loop Power Supply while
at the same time measuring the current.
• Voltage Measurement
PCE-MCA 50 is capable of voltage measurement. The following
picture displays the connection for voltage measurement.
• Frequency Measurement
PCE-MCA 50 is capable of frequency measurement. The following
picture displays the connection for frequency measurement.
Also check the Trigger Level setting. There you can specify the
trigger level and whether to use a test voltage during the frequency
measurement
• Pulse Count Measurement

PCE-MCA 50 is capable to count number of pulses. The following
picture displays the connection for pulse count measurement.
Check the Trigger Level setting to specify the trigger level and
whether to use a test voltage during the pulse counting. Also check
the Trigger Edge (Rising or Falling) setting so it suits your need.

➢ ET (Electrical source Terminal) Terminals
Terminals for Simulating voltage, current, supplying loop power types
refer specification sheet on page no. 79 Section 6.7
• Current Generation
In source mode PCE-MCA 50 provides the supply power to the
loop.
The following picture displays the connection for current source for
different mode.
➢ mA Current Source
➢ mA 2-Wire Source
• Voltage Generation
PCE-MCA 50 is capable of voltage generation the following picture
displays the connection for voltage source.

➢ RTD Terminals
Terminals for measuring & simulating RTD / Ω. For RTD/Ω types refer
specification sheet on Page No.79- 82 Section 6.8, 6.9, 6.10, 6.11
• RTD/Resistance Source
PCE-MCA 50 is capable of RTD/Resistance generation. The
following picture displays the connection for RTD and Resistance
simulation. In RTD simulation PCE-MCA 50 mimics an RTD. The
instrument under test generates the current for the RTD
measurement.PCE-MCA 50 controls the voltage across its terminals
so that the resistance (voltage to Current ratio) corresponds to the
simulated temperature. Use of 2, 3 or 4-wire connection is up to the
receiver instrument. Use only the two leftmost terminals with every
wiring option. Connect the possible third and fourth wire according to
the Requirements of the connected instrument but use only the two
leftmost terminals.

• RTD / Resistance measurement
PCE-MCA 50 is capable of RTD/Resistance measurement. The
following picture displays the connection for RTD and Resistance
measurement.
➢ 2-Wire RTD Measurement
Two leftmost terminals are used in 2-wire systems. PCE-MCA
50 displays the selected wiring system in run page. PCE-MCA
50 sources current through the resistor and measure the
voltage drop across same terminals. The result is acceptable, if
the resistance of the connection wires is significantly smaller
than actual measured resistance.
➢ 3-Wire RTD Measurement
PCE-MCA 50 sources current through the resistor and measure
the voltage drop across the entire current loop and across the
upper side connection wire as shown in figure. If both left side
connection wires are identical, PCE-MCA 50 can compensate
for the resistance of the connection wires.
➢ 4-Wire RTD Measurement
PCE-MCA 50 sources current through the resistor from two left
side terminals and measure the voltage drop across the resistor
from the two right side terminals. The 4-wire method gives the

resistance between the terminals of the resistor; it is insensitive
to the resistance of the connection wires.
➢ TC Terminals
Terminal for measuring & simulating thermocouples and mV. This
terminal accepts a miniature polarized thermocouple plug with flat, in-
line blades spaced 7.9 mm (0.312 in) center to center.
For specification refer Section 6.12
PCE-MCA 50 supports measurement and simulation of Thermocouple
and mV.
➢ Frequency Terminals
PCE-MCA 50 is capable of Frequency Generation. The following
picture displays the connection for Frequency Generation.
For specification refer Section 6.15

➢ Pulse Terminals
PCE-MCA 50 is capable of Pulse Generation. The following picture
displays the connection for Pulse Generation. For specification refer
Section 6.16
