This module must only be used to replace defective modules in an existing installation. For new installations, please use PD 840 instead
The module contains 16 analog input channels for voltage (0-100 mV) or thermocouple inputs (type R, S, B, J, T, E, K & N) and one Pt-100 input. The module provides internal conversion of voltage measurements into engineering units. In case of thermocouple utilisation, ranging and linearisation are automatically applied. The input signals are filtered, and suppressed against 50 and 60 Hz interference.
Supply voltage: 24 V DC.
16 High resolution (15 bit) 0-100mV or Thermocouple inputs
Linearisation for Thermocouple types: R,S,B,J,T,E,K & N
1 High resolution (15 bit) Pt-100 input
Filtered input signals
Suppression of 50 & 60 Hz noise
High and Low level limit swich on each channel
Advanced self test facility
Overload protection
P-NET Fieldbus communication
Watchdog Timer
Rail Mounting module (DIN / EN)
EMC Approved (89/336/EEC)
The PD 3250 Analog Interface Module (AIM), is one of a collection of distributed process control
units, intended for use within a P-NET Fieldbus system. It provides highly a versatile interface for measurement transducers generating analog voltage signals (0 -100 mV), and for a wide range of Thermocouple devices.
The PD 3250 provides internal conversion of voltage measurements into any engineering unit
representing the analog process being monitored and controlled. In the case of thermocouple
utilisation, ranging and linearisation are automatically applied, depending on the particular
thermocouple type defined.
