Termination modules Parts of the H-S81-HS System
2.5.4 S81-T8002-1
Description
This module transforms the remote Host serial
output signal from RS232 to current loop with
galvanic insulation. The module is passive and
therefore needs an actively operating converter
on the other end. With this module it is possible
to connect a remote Host computer to a maximum
distance of 2,000 meters.
Technical Features
Status Indications
The module includes 5 x SMD LEDs with the following functions:
