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
Dual flowmeter input: 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.
RESET TOTAL
Function
Terminal input to reset total remotely or to lock the “Clear total” button
Type IB
Internally pulled-up switch contact - NPN
Pulse duration
100 msec (minimum)
A.3
OUTPUT
DIGITAL OUTPUT
Function
Transmitting scaled accumulated total (positive and negative) or input pulse retransmission
Scaled output
Output D1-D2: max. frequency 500 Hz.
Output D5-D6: 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 OT
Two passive transistor outputs (NPN) - not isolated. 300 mA – 50 V @ 25°C
Type OR
Two isolated electro-mechanical relay outputs (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
ANALOG OUTPUT
Function
Transmitting differential flowrate, forward flow or reverse flow
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)
