Option A

Option details A

(0)4 - 20mA. Analog input signal can be scaled to any desired range within 0 - 20mA

Accuracy: Resolution: 16 bit. Error < 0.01mA / ± 0.05% FS. Low level cut-off programmable.
Span: 0.001 / 999,999 with variable decimal position.
Update time: Four times per second.
Voltage drop: Type A: max. 1V DC @ 20mA.
Voltage drop: Type A - PL (loop powered): max. 2.6V DC @ 20mA.
Relationship: Linear and square root calculation.
Note: For signal type A and U: external power to sensor is required; e.g. type PD / PM.

Option U

Option details U

0 - 10V DC. Analog input signal can be scaled to any desired range within 0 - 10V DC.

Accuracy: Resolution: 16 bit. Error < 0.01mA / ± 0.05% FS. Low level cut-off programmable.
Span: 0.001 / 999,999 with variable decimal position.
Update time: Four times per second.
Load impedance: Type U: 3kOhm.
Relationship: Linear and square root calculation.
Note: For signal type A and U: external power to sensor is required; e.g. type PD / PM.

Option P

Option details P

Coil / sine wave (minimum 20mVpp or 80mVpp - sensitivity selectable), NPN/PNP (open collector/drain), reedswitch, Namur, active pulse signals 8 - 12 and 24V DC.

Frequency Minimum 0Hz - maximum 7kHz for total and flow rate. Maximum frequency depends on signal type and

internal low-pass filter. E.g. reed switch with low-pass filter: max. frequency 120Hz.

K-Factor 0.000010 - 9,999,999 with variable decimal position.

Low-pass filter Available for all pulse signals.

Option ZF: coil sensitivity 10mVpp. Option ZG: coil sensitivity 5mVpp.
