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)
