App

Index

24 VDC Transmitter Power Supply (/TPS2 and /TPS4)

Item

Specifications

Number of loops

2 (/TPS2) or 4 (/TPS4)

Output voltage

22.8 to 25.2 VDC (under rated load current)

Rated output current

4 to 20 mADC

Max. output current

25 mADC (overcurrent protection operation current: approx. 68 mADC)

Allowable conductor resistance

RL ≤ (17.8 – minimum transmitter operation voltage)/0.02 A

where 17.8 V is the result obtained by subtracting the maximum drop voltage of 5 V when the load

shunt resistance is 250 Ω from the minimum output voltage of 22.8 V

Max. length of wiring

2 km (when using the CEV cable)

Insulation resistance

20 MΩ or more at 500 VDC between output terminal and ground

Dielectric strength

500 VAC (50/60 Hz, I = 10mA) for one minute between output terminal and ground

500 VAC (50/60 Hz, I = 10mA) for one minute between output terminals

Pulse Input (/PM1)

Item

Specifications

Pulse input
Number of inputs

3 (8 when using the remote control input terminals)

Input type

Isolated from the main circuitry through a photocoupler and built-in isolated power supply for the

input terminals.

Shared common for pulse inputs.

Input type and signal level Voltage-free contact Contact closed at 200 Ω or less and contact open at 100 kΩ or greater

Open collector

ON voltage: 0.5 V or less (sink current 30 mA or more), leakage current when

OFF: 0.25 mA or less

Counting

Counts the rising edges of pulses.

For voltage-free contact input: Contact open to contact close

For open collector:

Voltage level of the terminal H from high to low

Allowable input voltage 30 VDC
Max. sampling pulse period 100 Hz
Minimum detected pulse width

5 ms or more for both low (closed) and high (open)

Pulse detection period

Approx. 3.9 ms (256 Hz)

Pulse measuring accuracy ±1 pulse
Pulse count interval

Scan interval or 1 s

Miscellaneous

Pulse input terminals can be used as remote control input terminals, isolated from remote control

input terminals

Remote control

Number of inputs: 5. Same as remote control (/R1) for the other specifications

Computation function

Same as the computation function (/M1)

Calibration Correction (/CC1)

Item

Specifications

Calibration correction method

Corrects the measured value of each channel using segment linearizer approximation.

Number of segment points: 2 to 16 (including the start and end points)
