Bieler+Lang GmbH Gasmesscomputer type : GMC 8420 12.600765.2 气体检测和报警系统
The controller is designed to be connected to up to four gas detectors
with 4-20mA signal interface. There are also visual indicators for error pre alarm
and main alarm for each measurement channel. The present reading is shown
in the display. For the control of technical equipment and warning devices there
are three freely programmable output relays (230VAC/4A). These can be programmed
with the messages alarm 1, alarm 2 or horn. A further output relay is permanently
assigned to the error function. The output extension RK 8420 can be connected
at the integral DC switch. This module provides the option of four more
freely-programmable output relays (230VAC/4A)
Parameters can be freely set for each measurement channel:
- Alarm threshold for Alarm 1
- Alarm threshold for Alarm 2
- Alarm when signal is outside measurement range
- Alarm latching / non latching
- zero capture
