SENSOR EXCITATION
Type AH/PB/PX Terminal S3: 3 VDC for pulse signals and 1.2 VDC for coil pick-up, I
out
max. 100 μA. This is not a
real sensor supply. Only suitable for sensors with a very low power consumption like coils (sine
wave) or reed switches.
Type PD Terminal P3:
● 8.2 VDC, Iout max. 20 mA
● 12 VDC, Iout max. 30 mA
● 24 VDC, Iout max. 75 mA (varies depending on input supply voltage)
A.2 INPUT
FLOWMETER
Type P Coil / sine wave (COIL-HI: 20mVpp or COIL-LO: 90mVpp sensitivity selectable), NPN, PNP,
reed switch, NAMUR, active pulse signals 8 or 24 VDC
Frequency Minimum 0Hz - maximum 10 kHz for total and flowrate. Maximum frequency depends on signal
type and internal low-pass filter. E.g. reed switch with low-pass filter (max. frequency 120 Hz)
K-Factor 0.000010 - 9,999,999 with variable decimal position
Low-pass filter Available for all pulse signals
Type ZF: Coil
sensitivity
10 mVpp.
Type ZG: Coil
sensitivity
5 mVpp.
REMOTE CONTROL
Function Two independently configurable remote control inputs to:
● Reset total
● End delivery and print ticket
● Print totalizer ticket
● Reprint last printed ticket
Type IR Internally pulled-up switch contact - NPN
Pulse duration 100 msec (minimum)
A.3 OUTPUT
DIGITAL OUTPUT
Function Transmitting linearized accumulated total (scaled pulse) or input pulse retransmission
Scaled output Output D1: max. frequency 500Hz.
Output D5: max. frequency 4Hz, recommended use below 0.5Hz
Pulse length user definable between 1msec up to 10 seconds
Retransmission output Square wave output based on frequency of (sine wave or coil) input signal. Maximum frequency
10kHz with a 50% duty cycle, minimum on and off-time 50µs
Type OR One isolated electro-mechanical relay output (NO).
Maximum resistive load: 2A @ 250 VAC / 30 VDC.
Maximum inductive load: 0.5A (pilot duty applications).
Note 1: Requires 24 – 27 VDC and supplied via P5 - P6.
Note 2: Type OT remains available.
Note 3: Not used in pulse retransmission mode
Type OT One passive transistor output (NPN) - not isolated. 300 mA – 50 V @ 25°C
ANALOG OUTPUT
Type AH Galvanically isolated, loop powered 4 – 20 mA output
Accuracy 12 bit. Error 0.03% @ 20°C (Typical 45 ppm/°C).
Can be scaled to any desired range
Supply voltage 10V (lift-off voltage) - 27VDC
Max load 700 ohm @ 24VDC (24V – 10V / 20mA)
