)
• Slide resistance value: 100 to 2.5 k of overall resistance
(burnout detection for sliding wire provided)
• Measuring resolution: 0.1% of overall resistance
Loop Power Supply
Power is supplied to a two-wire transmitter.
(15 V DC: terminals
14

; 24 V DC: terminals

-
44
)
A resistor (10 to 250 ) connected between the controller and transmitter converts a
current signal into a voltage signal, which is then read via the PV input terminal.
Supply voltage: 14.5 to 18.0 V DC, max. 21 mA (provided with a protection circuit
against a field short-circuit); 21.6 to 28.0 V DC, max. 30 mA (only for models with 24 V
DC loop power supply)
Retransmission Output
Either PV, target setpoint, or control output is output.
Either the retransmission output or the loop power supply can be used with terminals

)
• Output signal: 4-20, 0-20, 20-4, or 20-0 mA DC (where, outputting signal levels of less
than 0 mA is not feasible)
• Load resistance: 600 or less
• Output accuracy: 0.1% of span (5% of span for 1 mA or less.)
Under standard operating conditions (23 2C, 55 10% RH, power frequency of 50/
60 Hz)
Control Output
Universal output system, The output type can be selected with the software.
Relay contact output(s) for the position proportional type

Number of outputs 1 or 2 (two for heating/cooling type),
switched between a voltage pulse output
and current output.
Output signal 4-20, 0-20, 20-4, or 20-0 mA DC
Load resistance 600 or less
Output accuracy 0.1% of span
(5% of span for 1 mA or less)
Under standard operating conditions (23 2 C,
55 10% RH, power frequency of 50/60 Hz)
