2.1

The pen recorder provides 1, 2 or 3 chan-

nels for recording; the channels are isolated

from each other by optocouplers. Channel 1

can be used to write text in addition to the

signal trace. All three channels are zeroed

using Hall sensors.

A 24-place 5x 5 LED dot matrix display is

available for signal indication and program-

ming. Operation is by eight keys on the in-

strument front and via a setup program us-

ing a PC. The configuration data are stored

permanently in EEPROM.

Input signals include resistance thermome-

ters, resistance transmitters, thermocouples,

standard current and voltage signals. The

necessary linearisation is performed auto-

matically. Eight logic inputs are available for

operating functions. An external relay mod-

ule ER8 for rail mounting supplements the

pen recorder by eight switching outputs.

A 2-wire transmitter can be operated from

an isolated supply. The watchdog monitors

the recorder operation and triggers a restart

in case of a fault. On a power failure the

real-time clock is supplied by a lithium bat-

tery or a storage capacitor.

A summary of all recorder parameters is

given in the Appendix ( Section 12.6).
